DETAILED DESCRIPTION

[0028] Disclosed herein is a system for applying eyelashes including two micro-robots, a first micro-robot and a second micro-robot, made of a plurality of magnets arranged in an alternating magnetic array. In some embodiments, the first micro-robot includes a wire comb having an attachment end that is threaded through a tube on the second micro-robot. In some embodiments, the second micro-robot includes one or more grippers configured to mate with the attachment end of the wire comb to retain an eyelash or eyelash cluster. By sliding the second micro-robot along the wire comb, the system may grip, retain, and release eyelashes or eyelash clusters to apply a customized eyelash style to a user. In some embodiments, the system may slide or levitate over a flexible PCB substrate to allow for precise positioning of the two micro-robots.

[0029] FIGS. 1A-1F are example micro-robots, in accordance with the present technology. In some embodiments, disclosed herein are systems for applying eyelashes, using one or more micro-robots based on printed circuit board (PCB) drivers.

[0030] FIG. 1A is an example micro-robot 200 including four magnets 205A, 205B, 205C . . . 205N. In some embodiments, the four magnets (also referred to herein as a plurality of magnets) 205A, 205B, 205C . . . 205N are disposed in an array with an alternating magnetization. For example, in FIG. 1A, magnets 205A (top) and 205C (bottom) may have a first magnetization and magnets 205B (left) and 205N (right) may have a second magnetization, opposite the first magnetization. In some embodiments, the plurality of magnets 205A, 205B, 205C . . . 205N are arranged like a checkerboard. In some embodiments, the plurality of magnets 205A, 205B, 205C . . . 205N may be comprised of any material, such as nickel, iron, samarium, or the like. In some embodiments, the plurality of magnets 205A, 205B, 205C . . . 205N are comprised of neodymium (NdFeB). In an embodiment, the plurality of magnets comprises one or more magnetic materials. Non-limiting examples of magnetic materials include ferromagnetic elements (e.g., cobalt, gadolinium, iron, or the like), rare earth elements, ferromagnetic metals, ferromagnetic transition metals, materials that exhibit magnetic hysteresis, or the like or combinations thereof. Further non-limiting examples of magnet materials include nickel, iron, samarium, or the like or combinations thereof.

[0031] FIG. 1B shows an example micro-robot 200 having a plurality of magnets 205A, 205B, 205C . . . 205N, an applicator 210, and an eyelash (or cluster of eyelashes) L. In some embodiments, the applicator 210 is configured to hold an eyelash or eyelash cluster, for eventual application to an eyelid. As used herein, the term eyelash cluster means two or more eyelashes that have been grouped together, either by being manufactured together or attached together, such as with adhesive. Individual eyelashes within an eyelash cluster may have a same length, thickness, color, finish, or the like, or may have different lengths, thicknesses, colors, finishes, etc.

[0032] FIGS. 1C-1D show example micro-robots 200 positioned on a printed circuit board (PCB) substrate 105. In some embodiments, the checkerboard configuration of a plurality of magnets (such as plurality of magnets 205A, 205B, 205C . . . 205N) in conjunction with a graphite layer of the substrate 105 confines the micro-robot 200 to a specific location in (x, y, z). A magnetic potential well may be generated to localize the micro-robot 200. In some embodiments, a magnetic force is generated by four PCB current traces located inside the substrate 105. Pairs of these four traces are typically driven in quadrature, behaving very similarly to a linear stepper motor. While driving the currents in quadrature controls the relative phase between the pairs of currents and therefore the micro-robot 200 in-plane position, modulating the absolute magnitude of the traces increases or decreases the out-of-plane force between the board and the robot providing about 40 to 70 m of Z motion.

[0033] FIG. 1C shows a sliding substrate system. In such embodiments, the graphite layer of the substrate 105 may be thin, such as 25 to 100 m thick. In such systems, the micro-robot(s) 200 are configured to slide across the substrate.

[0034] FIG. 1D shows a levitating substrate system. In such embodiments, the graphite layer of the substrate 105 may be thick, such as 0.5 mm thick. In such embodiments, the micro-robot 200 may levitate off of the substrate 105 by an elevation E.

[0035] FIGS. 1E-1F show various layouts for micro-robots 200. It should be understood that any number of magnets may be included in the plurality of magnets 205A, 205B, 205C . . . 205N. In some embodiments, the plurality of magnets 205A, 205B, 205C . . . 205N are disposed in an alternating orientation, where the magnetization is alternated between adjacent magnets.

[0036] In some embodiments, the micro-robot(s) 200 are controlled by the local trace pattern and currents. That is, the micro-robot's control is area- or zone-based rather than one that moves with the micro-robot (as would be the case for conventional motorized robots). Zone control has both advantages and disadvantages for multi-agent control. The disadvantage of zone control is that two micro-robots in close proximity may not be independently controlled unless they are in different independent zones. The advantage of zone control is that large numbers of micro-robots may be controlled to execute the same motion in parallel using only a few control channels. The control zone approach generally reduces the numbers of control channels needed since the micro-robots do not need to carry extra control channels in areas which need, for example, only one degree-of-freedom for transport.

[0037] In some embodiments, the substrate or other lithographically patterned micro-circuits, enable large and complex drive systems to be made relatively easily using conventional batch fabrication. In some embodiments, the systems disclosed herein could be as large as 30 cm30 cm, or even larger. In some embodiments, the micro-robot(s) may transition between separate substrates 105 if they are in proximity of one another.

[0038] In some embodiments, as described herein, micro-robots may be configured to cooperate with one another by doing different steps in the process of applying eyelashes to a single eye or a single user having two eyes. For example, one or more micro-robots 200 may be configured to separate out eyelashes, another micro-robot may be configured to apply the lash, and yet another micro-robot may be configured to apply an eyelash glue or adhesive. In some embodiments, multiple micro-robots may work together more directly, as explained herein.

[0039] FIGS. 2A-2B is an example system of applying eyelashes 2000, in accordance with the present technology. In some embodiments, system 2000 (also referred to herein as applicator system 2000) includes a first micro-robot 200A having a first plurality of magnets 205A-i, 205B-i, 205C-i . . . 205N-i and a wire comb 215, and a second micro-robot 200B having a second plurality of magnets 205A-ii, 205B-ii, 205C-ii . . . 205N-ii, a tube 210B, and a gripper 225.

[0040] In some embodiments, the first micro-robot 200A includes a first plurality of magnets 205A-i, 205B-i, 205C-i . . . 205N-i. In some embodiments, the first plurality of magnets 205A-i, 205B-i, 205C-i . . . 205N-i is arranged in an array of alternating magnetization, as explained herein. In some embodiments, the first plurality of magnets 205A-i, 205B-i, 205C-i . . . 205N-i is a plurality of NdFeB magnets.

[0041] In some embodiments, the first micro-robot 200A also includes a holder 210A configured to retain the wire comb 215. In some embodiments, the wire comb 215 is configured to slide into the holder 210A. In some embodiments, the wire comb 215 is integrated into the holder 210A.

[0042] The wire comb 215 may be made of metal, ceramic, carbon, plastic, or a combination thereof. In some embodiments, the wire comb 215 includes an attachment end 220. As shown in FIGS. 3A-3D, the attachment end 220 may be disposed at substantially a 45-degree angle from the wire comb 215 to form a hook shape.

[0043] In some embodiments, the second micro-robot 200B includes a second plurality of magnets 205A-ii, 205B-ii, 205C-ii . . . 205N-ii. In some embodiments, the second plurality of magnets 205A-ii, 205B-ii, 205C-ii . . . 205N-ii is arranged in an array of alternating magnetization, as explained herein. In some embodiments, the second plurality of magnets 205A-ii, 205B-ii, 205C-ii . . . 205N-ii is a plurality of NdFeB magnets.

[0044] In some embodiments, the second micro-robot 200B further includes a tube 210B. The tube 210B is configured to slide alone the wire comb 215 of the first micro-robot 200A. In this manner, the second micro-robot 200B may move back and forth (such as in the direction of the arrow in FIG. 2A) along the wire comb 215.

[0045] In some embodiments, the second micro-robot further comprises a gripper 225. In some embodiments, the gripper 225 is configured to mate with the attachment end 220 of the wire comb 215, as shown in more detail in FIGS. 3A-3D. In some embodiments, the gripper 225 has a V-shaped end.

[0046] In operation, the first micro-robot 200A is secured to a first location. In some embodiments, the first location is on a substrate (such as substrate 105). The second micro-robot 200B may then be slid along the wire comb 215 through the tube 210B of the second micro-robot 200B. In some embodiments, the second micro-robot 200A slides towards the attachment end 220 of the wire comb 215, as shown in FIGS. 2A-2B, such that the gripper 225 contacts the attachment end 220. In some embodiments, an eyelash or cluster of eyelashes (not pictured in FIGS. 2A-2B) is gripped between the gripper 225 and the attachment end 220. The first micro-robot 220A and/or the second micro-robot 200B may then be positioned to apply the eyelash or cluster of eyelashes to an eyelid. In some embodiments, the first micro-robot 220A and the second micro-robot 200B are configured to move together, such that the distance between the first micro-robot 220A and the second micro-robot 200B does not change. Once the micro-robots 200A, 200B are in position, the gripper 225 may be retracted away from the attachment end 220, such as by moving the second micro-robot 200B along the wire comb 215 in the opposite direction. Then, the eyelash or eyelash cluster is applied to the eyelid. In some embodiments, the eyelash or eyelash cluster may include an adhesive, such as eyelash glue. In some embodiments, a user of the system 2000 may apply adhesive, magnetic eyeliner, or the like to their eyes before using system 2000. In some embodiments, the second micro-robot 200B may remain in place for a set period of time (such as 60 seconds) before retracting along the wire comb 215 to ensure the eyelash or cluster of eyelashes remain in place, prior to releasing the eyelash or cluster of eyelashes.

[0047] In some embodiments, throughout this operation, the first micro-robot 200A and/or the second micro-robot 200B may slide across a substrate 105, as shown in FIG. 1C. In other embodiments, the first micro-robot 200A and/or the second micro-robot 200B may levitate across a substrate 105, as shown in FIG. 1D. In some embodiments, the first micro-robot 200A and the second micro-robot 200B are configured to slide across or levitate over a flexible substrate, as explained herein.

[0048] FIGS. 3A-3F are example grippers and attachment ends of the system 2000 of applying eyelashes of FIGS. 2A-2B, in accordance with the present technology.

[0049] In some embodiments, the system 2000 includes a single gripper 225, as shown in FIGS. 3A-3D. The gripper 225 may move back and forth as the second micro-robot 200B moves along the wire comb. As the gripper 225 moves towards the attachment end 220 of the wire comb 215, a V-shaped end of the gripper 225 contacts and mates with the attachment end 220. As shown in FIGS. 3C-3D, an eyelash L may be gripped between the gripper 225 and the attachment end 220 in this manner.

[0050] In some embodiments, the system 2000 includes a first gripper 225A, and a second gripper 225B, as shown in FIGS. 1E-1F. The first gripper 225A and the second gripper 225B may be offset from one another by an offset distance O. In some embodiments, the offset distance is slightly larger than the attachment end 220. In such embodiments, as shown in FIG. 1F, an eyelash L may be gripped by the first gripper 225A, the second gripper 225B, and the attachment end 220. The attachment end 220 may slot into the offset distance O to retain the eyelash L. In some embodiments, both the first gripper 225A and the second gripper 225B have a V-shaped end.

[0051] FIGS. 4A-4C are example micro-robot crane systems 4000, in accordance with the present technology. In some embodiments, a system for applying eyelashes includes a robot crane system 4000.

[0052] In some embodiments, such as shown in FIGS. 4A-4B, the system 4000 includes a single micro-robot crane. The robot crane system 4000 may include a back micro-robot 400A having a first plurality of magnets 405A, 405B, 405C . . . 405N, a rotary bearing 415, and a separation arm 430 including a separation tip 440. In some embodiments, the robot crane system 4000 further includes a front micro-robot 400B having a second plurality of magnets 410A, 410B, 410C . . . 410N, a mount 420, and mechanical stop 425.

[0053] In some embodiments, the back micro-robot 400A includes a first plurality of magnets 405A, 405B, 405C . . . 405N. In some embodiments, the first plurality of magnets 405A, 405B, 405C . . . 405N is arranged in an array of alternating magnetization, as explained herein. In some embodiments, the first plurality of magnets 405A, 405B, 405C . . . 405N is a plurality of NdFeB magnets.

[0054] In some embodiments, the back micro-robot 400A further includes a rotary bearing 415. The rotary bearing 415 is configured to retain the separation arm 430, and allow the separation arm 430 to move up and down over the mount 420 of the front micro-robot 400B, as shown in FIG. 4B.

[0055] In some embodiments, the separation arm 430 includes a separator tip 440 configured to contact a lash line and separate one or more lashes from one another, as shown in FIGS. 4B and 5A-5G. In some embodiments, the separator tip 440 is disposed at an angle from the separator arm 430.

[0056] In some embodiments, the front micro-robot 400B includes a second plurality of magnets 410A, 410B, 410C . . . 410N. In some embodiments, the second plurality of magnets 410A, 410B, 410C . . . 410N is arranged in an array of alternating magnetization, as explained herein. In some embodiments, the second plurality of magnets 410A, 410B, 410C . . . 410N is a plurality of NdFeB magnets.

[0057] The front micro-robot 400B may further include a mount 420 configured to slide along the separation arm 430. The mount 420 is configured to hold the separation arm 430 and slide backwards and forwards along the separation arm 430 to raise and lower the separation arm 430, as shown in FIG. 4B.

[0058] In some embodiments, the front micro-robot 400B further includes a mechanical stop 425, which further retains the separation arm 430. The mechanical stop 425 may prevent the separation arm from disengaging from or falling from the mount 420.

[0059] In operation, the back micro-robot 400A may remain stationary. The front micro-robot 400A may move backwards, in direction B. As the front micro-robot 400A moves in direction B, the separation arm 430 is raised upwards with the rotary bearing in the direction U. Because the separation arm 430 contacts mount 420, as the front micro-robot 400A moves backwards, the mount 420 increases an angle between the substrate 105 and the separation arm 430. In this manner, the separation tip 440 can contact a lash line of an eyelid, as shown in FIG. 4B. The separator tip 440 may fit between individual lashes of a plurality of lashes L1, L2, L3 . . . . LN.

[0060] In some embodiments, after contacting the lash line with the separation tip, the back micro-robot 400A and the second micro-robot 400B may move together in a direction perpendicular to direction B to separate adjacent eyelashes, as shown in detail in FIG. 5E.

[0061] In some embodiments, throughout this operation, the back micro-robot 400A and/or the front micro-robot 400B may slide across a substrate 105, as shown in FIG. 1C. In other embodiments, the back micro-robot 400A and/or the front micro-robot 400B may levitate across a substrate 105, as shown in FIG. 1D. In some embodiments, the back micro-robot 400A and the back micro-robot 400B are configured to slide across or levitate over a flexible substrate, as explained herein.

[0062] In some embodiments, such as shown in FIGS. 4C, the system 4000 includes a first robot crane and a second robot crane. In such embodiments, the system 4000 includes first robot crane having a first back micro-robot 400A-i having a first plurality of magnets 405A-i, 405B-i, 405C-i . . . 405N-i, a first rotary bearing 415-i, and a first separation arm 430-i including a first separation tip 440-i. In some embodiments, the first robot crane further includes a first front micro-robot 400B-i having a second plurality of magnets 410A-i, 410B-i, 410C-i . . . 410N-i, a first mount 420-i, and first mechanical stop 425-i.

[0063] The second robot crane may have a second back micro-robot 400A-ii having a third plurality of magnets 405A-ii, 405B-ii, 405C-ii . . . 405N-ii, a second rotary bearing 415-ii, and a second separation arm 430-ii including a second separation tip 440-ii. In some embodiments, the second robot crane further includes a second front micro-robot 400B-ii having a fourth plurality of magnets 410A-ii, 410B-ii, 410C-ii . . . 410N-ii, a second mount 420-ii, and a second mechanical stop 425-ii.

[0064] As shown in more detail in FIGS. 5A-5G, the first robot crane and the second robot crane may work in tandem to separate adjacent lashes.

[0065] FIGS. 5A-5G are process diagrams of a system of applying eyelashes, in accordance with the present technology. In some embodiments, a robot crane system 4000 including a first robot crane and a second robot crane as described herein is used to separate adjacent eyelashes of a user's eye.

[0066] In FIG. 5A, both the first robot crane and the second robot crane move together and forwards in the direction F. Both the front micro-robots (such as front micro-robots 400B, 400B-i, 400B-ii) and the back micro-robots (such as back micro-robots 400A, 400A-i, 400-ii) move together in the same direction F. In some embodiments, the direction F is towards an eye of a user.

[0067] In FIG. 5B, the first robot crane and the second robot crane in robot crane system 4000 reach the eyelid. One skilled in the art should understand that the eyelid and lashes shown in FIG. 5B are not to scale and have been simplified for clarity.

[0068] In FIG. 5C, the first front micro-robot of the first crane and the second front micro-robot of the second crane move backwards in the direction B. As this occurs, the first separation arm and the second separation arm move upwards in direction U until the first separation tip and the second separating tip contact a lash line and lashes of the eyelid. The first separating tip contacts a first lash L1, while the second separation tip contacts an adjacent lash LA.

[0069] In FIG. 5D, the first micro-robot moves in a first direction L, while the second micro-robot moves in a second direction R, opposite the direction L. In this way, the first lash L1 and the adjacent lash LA are separated by being bent in opposite directions. In some embodiments, this exposes a gap in the lash line of the eye, as shown in FIG. 5D.

[0070] In FIG. 5E, a system for applying eyelashes 2000 (as shown and described in FIGS. 2A-3F) moves forwards in direction F, towards the eyelid (and therefore towards the gap in the lash line of the eye, between the first lash L1 and the adjacent lash LA). The gripper of system 2000 may be contacting the attachment end. In this way the gripper and the attachment end may hold an eyelash or cluster of eyelashes between them.

[0071] In FIG. 5F, the system 2000 contacts the lash line. The second micro-robot (and therefore the gripper) may move backwards in direction B to release the eyelash or cluster of eyelashes as a new lash (NL) into the gap between the first lash L1 and the adjacent lash LA.

[0072] In FIG. 5G, the entire system 2000 moves backwards in direction B, disengaging from the eyelid. A new lash NL has been applied by system 2000.

[0073] In some embodiments, throughout this process, the first robot crane, the second robot crane, and/or the system 2000 may slide across a substrate 105, as shown in FIG. 1C. In other embodiments, the first robot crane, the second robot crane, and/or the system 2000 may levitate across a substrate 105, as shown in FIG. 1D. In some embodiments, the first robot crane, the second robot crane, and/or the system 2000 are configured to slide across or levitate over a flexible substrate, as explained herein.

[0074] It should be understood that in some embodiments, lashes may be applied to both eyes of a user, such as with a third robot crane, a fourth robot crane, and a second system 2000. In some embodiments, eyelashes may be applied to both eyes concurrently or sequentially. In some embodiments, after applying lashes to the first eye, the systems 2000, 4000 shown in FIGS. 5A-5F may move to the second eye of a user. In other embodiments, a user may adjust so that the systems 2000, 4000 are near their second eye.

While three cameras are shown in FIGS. 7A-7B, it should be understood that any number of cameras may be used as a camera system, including a single camera. In some embodiments, the one or more cameras 1005A, 1005B, 1005C are configured to analyze a user 300, the one or more micro-robots 200, and the flexible PCB substrate 105. In some embodiments, the one or more cameras 1005A, 1005B, 1005C are communicatively coupled with a processor 1010. The processor may be configured to determine a desired height of the one or more linear actuators 115A, 115B, 115C . . . 115N, a new position of the one or more micro-robots, or both. In this manner, the one or more cameras 1005A, 1005B, 1005C can determine a location of each element and correctly position the flexible PCB substrate 105, the one or more micro-robots 200, the applicator 210, or a combination thereof with the processor 1010. While the processor 1010 is shown above the system 1000, it should be understood that the processor may be located anywhere, including incorporated directly into the system. In some embodiments, the processor 1010 may be a remote processor or else incorporated into a remote device such as a smart phone, desktop computer, laptop, or tablet. In some embodiments, the processor 1010 is configured to communicatively couple with the one or more cameras 1005A, 1005B, 1005C, the motor base 120, the one or more linear actuators 115A, 115B, 115C . . . 115N, and/or the one or more micro-robots 200.

[0087] In some embodiments, positioning the one or more micro-robots 200 onto the flexible PCB substrate 105 includes directing the one or more micro-robots 200 to slide or levitate over the flexible PCB substrate 105. In some embodiments, positioning the one or more micro-robots includes adjusting a pitch, yaw, roll, or a combination thereof of the one or more micro-robots 200 with the one or more linear actuators 115A, 115B, 115C . . . 115N under the flexible PCB substrate 105. Adjusting the position of the one or more micro-robots in one of or both of the ways described above allows the system 1000 to apply an eyelash with the one or more micro-robots 200.

[0088] In operation, a user 300 may rest their chin on the chin rest 720. In some embodiments, the chin rest 720 may be omitted. In some embodiments, the chin rest is adjustable to position the user 3000 to a location where the one or more micro-robots 200 can contact the user's lash line, eyelid, or the like. The one or more cameras 1005A, 1005B, 1105C may monitor the position, orientation, and/or angle of the one or more micro-robots 200. The one or more cameras 1005A, 1005B, 1005C may also determine a location of features of the user 3000 such as the eyes, lash lines, eyelashes, and eyelids.

[0089] In some embodiments, the first camera 1005A is positioned to view the flexible PCB substrate 105 from a top-down (or bird's eye view), the second camera 1005B is positioned to view the flexible PCB substrate 105 from an angle, and the third camera 1005C is positioned to view the flexible PCB substrate 105 from the side. However, one skilled in the art will recognize that the camera system 1005 may take any configuration.

[0090] In some embodiments, the one or more cameras 1005A, 1005B, 1005C transmit image data of the one or more micro-robots 200, the flexible PCB substrate 105, and/or the user 300 to the processor 1010. The processor may then analyze this image data and adjust a height of at least one linear actuator of the plurality of linear actuators 115A, 115B, 115C . . . 115N and/or adjust a position of the one or more micro-robots 200. In some embodiments, adjusting the position of the one or more micro-robots 200 comprises adjusting an angle of attack of the applicator 210 of the one or more micro-robots 200 with the plurality of linear actuators 115A, 115B, 115C . . . 115N.

[0091] In some embodiments, as shown in FIG. 7B, the processor 1010, in conjunction with the flexible PCB substrate 105 may position a first micro-robot 200A to apply a first eyelash L1 and position a second micro-robot 200B to apply a second eyelash L2. In such embodiments, the first micro-robot 200A and the second micro-robot 200B may move along the flexible PCB substrate in direction D, applying eyelashes as they pass the a user's first (left) eye. In some embodiments, the one or more micro-robots 200A, 200B may apply eyelashes contemporaneously. For example, the first micro-robot 200A may apply eyelashes to the user's first (left) eye and the second micro-robot 200B may apply eyelashes to the user's second (right) eye. In some embodiments, the flexible PCB substrate 105 may adjust the position of the one or more micro-robots 200A, 200B such that applicators 210A, 210B are able to apply eyelashes or eyelash clusters to a top lash line, a bottom lash line, or both.

[0092] In operation, a user 3000 may select an eyelash style, such as with an application on a communicatively coupled smart phone, a tablet, or a computer. In some embodiments, the smart phone, tablet, or computer houses the processor 1010. The user 3000 may modify their selection, view their selection on a photo or live feed of themselves, or receive a selection based on a questionnaire, personal preferences, or trending styles. After selecting the style, the user 3000 may then sit or stand at the system 1000. In some embodiments, the user 3000 rests their chin on the chin rest 720. The processor 1010 may then direct the one or more micro-robots 200 to apply one or more eyelashes or eyelash clusters to achieve the selected style. The one or more cameras 1005A, 1005B, 1005C monitor the one or more micro-robots 200 and the user 3000 to ensure the one or more micro-robots 200 are directed to a location capable of applying the one or more eyelashes or eyelash clusters to achieve the selected style. In some embodiments, the processor 1010 further instructs the one or more linear actuators 115A, 115B, 115C . . . 115N to adjust the flexible PCB substrate 105 to further position the one or more micro-robots 200.

[0093] FIG. 8 is a block diagram of an example system 800 for applying eyelashes, in accordance with the present technology.

[0094] In block 805, the system 800 may calculate intrinsic and extrinsic calibration of the system 800. In some embodiments, this is only done once. In some embodiments, calculating the intrinsic and extrinsic calibration includes determining an initial position of a flexible PCB substrate (such as flexible PCB substrate 105) one or more micro-robots (such as micro-robots 200, 200A, 200B, 400A, 400B, 400A-i, 400B-i, 400B-ii, and 400B-ii), and/or a user (such as user 300) of the system 800.

[0095] In block 810, stereo image is captured. In some embodiments, this is done with a camera system (such as camera system 1005, including one or more cameras 1005A, 1005B, 1005C).

[0096] In block 815, one or more micro-robots are detected in the stereo image (or image data). This allows system 800 to determine and receive three-dimensional (3D) coordinates of the one or more micro-robots. These coordinates may be referred to as the one or more micro-robot's position.

[0097] In block 820, a dense disparity map of the stereo images is generated. In some embodiments, generating the dense disparity map includes dynamic programming, where edge pixels of the stereo images are matched and a dense disparity map is obtained by filling in the spaces between two consecutive edge pixels.

[0098] In block 830, 3D region pixels are acquired.

[0099] Returning to block 810, after obtaining the stereo images, contemporaneously, key points of the eyelid may be detected in the stereo images in block 835.

[0100] In block 840, the eyelashes of an eye (or both eyes) are cropped and detected.

[0101] In block 845, a density of the eyelashes is estimated.

[0102] In block 850, the eyelid is split into 5 mm regions, and an initial region for eyelash application is selected.

[0103] In block 855, two-dimensional (2D) regions of pixels of the eyelid are acquired. In conjunction with the 3D region of pixels of the desired position of the one or more micro-robots of block 830, the one or more micro-robots can be moved to a correct region in block 875.

[0104] In block 870, eyelashes may be separated out be the one or more micro-robots and visualized again in block 810. The stereo images of the separated out eyelashes may go through the same processing steps in blocks 810-855.

[0105] In block 865, the length of the eyelashes may be estimated.

[0106] In block 860, the extension (eyelash and/or eyelash cluster) is applied.

[0107] FIGS. 9A-9C are example eyelash dispensers 9000, in accordance with the present technology. In some embodiments, the system 1000 includes an eyelash dispenser 9000. In some embodiments, the eyelash dispenser 9000 includes a body 905 having a plurality of slots.

In some embodiments, the applicators 910A, 910B, 910C, 910D . . . 910N are double pronged applicators configured to hold an eyelash or eyelash cluster L1, L2, L3, L4 . . . . LN. In some embodiments, the applicators 910A, 910B, 910C, 910D . . . 910N may be attachment ends (such as attachment end 220), separating tips (such as separating tip 440) or a combination thereof. Further, while the one or more micro-robots 900A, 900B, 900C, 900D . . . 900N are illustrated as having a particular form factor, it should be understood that the one or more micro-robots 900A, 900B, 900C, 900D . . . 900N may be any of the micro-robots described herein, including (such as micro-robots 200, 200A, 200B, 400A, 400B, 400A-i, 400B-i, 400B-ii, and 400B-ii). In some embodiments, each slot of the dispenser 9000 may include a micro-robot system, such as systems 2000, 4000, or a combination thereof. In some embodiments, the eyelashes or eyelash clusters L1, L2, L3, L4 . . . . LN are precoated, dipped, sprayed, or the like with an adhesive, such as eyelash glue, magnetic liner, or the like. In this manner, the eyelashes or eyelash clusters L1, L2, L3, L4 . . . . LN may be applied by holding the eyelashes or eyelash clusters L1, L2, L3, L4 . . . . LN to a user's lash line with the one or more micro-robots 900A, 900B, 900C, 900D . . . 900N.

[0109] As shown in FIG. 9B, in some embodiments, the dispenser 9000 may be inserted into the system 1000, such that the one or more micro-robots 900A, 900B, 900C, 900D . . . 900N are released onto a flexible printed circuit board (PCB) substrate 105 (as shown and described in FIGS. 6A-6E and 7A-7C. The one or more micro-robots 900A, 900B, 900C, 900D . . . 900N may then move in a direction (indicated by the arrow) towards the eyelid of a user (such as user 3000) to apply individual eyelashes or eyelash clusters.

[0110] In some embodiments, the dispenser 9000 (or the system 1000) includes a drum pod 930, as shown in FIG. 9C. In some embodiments, the drum pod 930 is preloaded with eyelashes L1, L2, L3 . . . . LN. In some embodiments, the drum pod is located inside the dispenser 9000, but in other embodiments, it may be located on the flexible PCB substrate 105, and the dispensed micro-robots 900A, 900B, 900N may move from the dispenser to the drum pod 930. As the drum pod 930 rotates, a single eyelash (or eyelash cluster) L1, L2, L3 . . . . LN is fed to a micro-robot (here, micro-robot 900B). The one or more micro-robots 900A, 900B, 900N may queue at the drum pod 930 to each receive their respective single eyelash or eyelash cluster L1, L2, L3 . . . . LN. After being fed an eyelash or eyelash cluster, the one or more micro-robots may then be repositioned at a lash line of a user's eye to apply their respective eyelash or eyelash cluster. In this manner, the same micro-robots may continue to receive and apply eyelashes/eyelash clusters to a user's eye. In some embodiments, after each eyelash or eyelash cluster L1, L2, L3 . . . . LN is applied, the one or more micro-robots 900A, 900B, 900N are recalled to the drum pod 930 to receive an additional eyelash or eyelash cluster.

[0111] In some embodiments, the single eyelashes, the eyelash clusters, or both are applied to a first eye and a second eye simultaneously. In some embodiments, each micro-robot of the one or more micro-robots 900A, 900B, 900N may be assigned to either the first eye or the second eye. In some embodiments, each micro-robot of the one or more micro-robots 900A, 900B, 900C may apply eyelashes or eyelash clusters to either eye. In some embodiments, single eyelashes, the eyelash clusters, or both are applied to a first eye and a second eye sequentially. In some embodiments, the flexible PCB substrate 105 may be adjusted as described herein as the one or more micro-robots 900A, 900B, 900N slide or levitate across it.

[0112] FIG. 10 is a method 10000 of using a system for applying eyelashes, in accordance with the present technology. In some embodiments, the method 10000 is carried out by the systems (such as systems 1000, 2000, 4000, 9000) shown and described herein. In some embodiments, the method 10000 includes one or more micro-robots (such as microrobots 200, 200A, 200B, 400A, 400A-i, 400A-ii, 400B, 400B-i, 400B-ii, 900A, 900B, 900C, 900N, or a combination thereof), a flexible PCB substrate (such as flexible PCB substrate 105), one or more linear actuators (such as one or more linear actuators 115A, 115B, 115C . . . 115N), a motor base (such as motor base 120), and one or more eyelashes or eyelash clusters (such as one or more eyelash or eyelash clusters L1, L2, L3, L4 . . . . LN).

[0113] In block 10005, one or more micro-robots are positioned onto the flexible PCB substrate. In some embodiments, positioning the one or more micro-robots includes directing the one or more micro-robots to a position below or at a lash line, eyelid, or eye of a user (such as user 3000). In some embodiments, such as when the one or more micro-robots together make up a system for applying eyelashes (such as system 2000 or micro-robot crane system 4000), positioning the one or more micro-robots includes positioning the one or more micro-robots in a predetermined proximity to one another.

[0114] In block 10010, a pitch, yaw, roll, or combination thereof is adjusted with the flexible PCB substrate. In some embodiments, this is done by actuating the one or more linear actuators with the motor base to bend, flex, or otherwise adjust the flexible PCB substrate. In some embodiments, such as when the one or more micro-robots includes an applicator (such as such as applicator 210, attachment end 220, separating tip 440, or applicator 910), adjusting the flexible PCB substrate may also adjust an angle of attack of the applicator.

[0115] In block 10015, an eyelash (or eyelash cluster) is applied with the one or more micro-robots, as shown and described herein.

[0116] FIG. 11 is another method 1100 of using a system for applying eyelashes, in accordance with the present technology. In some embodiments, the method 1100 is carried out by the systems (such as systems 1000, 2000, 4000, 9000) shown and described herein. In some embodiments, the method 1100 includes one or more micro-robots (such as microrobots 200, 200A, 200B, 400A, 400A-i, 400A-ii, 400B, 400B-i, 400B-ii, 900A, 900B, 900C, 900N, or a combination thereof), a flexible PCB substrate (such as flexible PCB substrate 105), one or more linear actuators (such as one or more linear actuators 115A, 115B, 115C . . . 115N), a motor base (such as motor base 120), and one or more eyelashes or eyelash clusters (such as one or more eyelash or eyelash clusters L1, L2, L3, L4 . . . . LN). In some embodiments, method 1100 further includes a camera system (such as one or more cameras 1005A, 1005B, 1005C), and a processor (such as processor 1010).

[0117] In block 1105, the one or more micro-robots are monitored with the camera system. In some embodiments, the camera system is configured to capture stereo images (or image data) of the one or more micro-robots, the flexible PCB substrate, and/or the user (such as a user's eye, lash line, or the like).

[0118] In block 1110, the camera system transmits the image data to the processor. In some embodiments, the processor analyzes the image data to determine a location of the one or more micro-robots, a location of a user's eye/lash line, a density of a user's eyelashes, and a desired location for the one or more micro-robots. The processor may direct the one or more micro-robots to the desired location, or to a secondary location close to the desired location, where if the flexible PCB substrate was adjusted, would result in the one or more micro-robots being in the desired location. For example, if the one or more micro-robots needed to be at a lash line of a first eye of the user, but the flexible PCB substrate was below the lash line of the user, the process may direct the one or more micro-robots to the secondary location below the lash line, with the intention of then adjusting the flexible PCB substrate to raise the one or more micro-robots to the lash line (i.e., the desired location).

[0119] In block 1115, the flexible PCB substrate is adjusted by adjusting the height of at least one linear actuator of the plurality of linear actuators. In some embodiments, a pitch, yaw, roll, or combination thereof of the one or more micro-robots is adjusted with the flexible PCB substrate. In some embodiments, this is done by actuating the one or more linear actuators with the motor base to bend, flex, or otherwise adjust the flexible PCB substrate. In some embodiments, such as when the one or more micro-robots includes an applicator (such as such as applicator 210, attachment end 220, separating tip 440, or applicator 910), adjusting the flexible PCB substrate may also adjust an angle of attack of the applicator. As described herein, in some embodiments, each linear actuator of the plurality of linear actuators is configured to be controlled independently from one another.

[0120] FIG. 12 is yet another method 1200 of using a system for applying eyelashes, in accordance with the present technology. In some embodiments, the method 1200 is carried out by the systems (such as systems 1000, 2000, 4000, 9000) shown and described herein. In some embodiments, the method 1100 includes one or more micro-robots (such as microrobots 200, 200A, 200B, 400A, 400A-i, 400A-ii, 400B, 400B-i, 400B-ii, 900A, 900B, 900C, 900N, or a combination thereof), a flexible PCB substrate (such as flexible PCB substrate 105), one or more linear actuators (such as one or more linear actuators 115A, 115B, 115C . . . 115N), a motor base (such as motor base 120), and one or more eyelashes or eyelash clusters (such as one or more eyelash or eyelash clusters L1, L2, L3, L4 . . . . LN). In some embodiments, method 1200 further includes a system for applying eyelashes (such as system 2000). In some embodiments, the system for applying eyelashes includes a first micro-robot (such as first micro-robot 200A in FIGS. 2A-2B), having a first plurality of magnets (such as first plurality of magnets 205A-i, 205B-i, 205C-i . . . 205N-i) and a wire comb (such as wire comb 215) with an attachment end (such as attachment end 220), and a second micro-robot (such as second micro-robot 200B in FIGS. 2A-2B) having a second plurality of magnets (such as second plurality of magnets 205A-ii, 205B-ii, 205C-ii . . . 205N-ii), a tube (such as tube 210B), and a gripper (such as gripper 225).

[0121] In block 1205, the first micro-robot is secured to a first location. In some embodiments, the first micro-robot retains the wire comb in a holder (such as holder 210A). In some embodiments, the first micro-robot remains stationary throughout method 1200.

[0122] In block 1210, the second micro-robot is positioned along the wire comb. In some embodiments, the second micro-robot includes the tube, which the wire comb is threaded through. In this manner, the second micro-robot can slide back and forth along the wire comb.

[0123] In block 1215, an eyelash (or eyelash cluster) is gripped between the gripper of the second micro-robot and the attachment end of the wire comb. The second micro-robot may slide along the wire comb to the attachment end until the gripper contacts the attachment end of the wire comb, securing the eyelash between the gripper and the attachment end. In some embodiments, the second micro-robot includes a first gripper (such as first gripper 225A) and a second gripper (such as second gripper 225B). The first gripper and the second gripper may be offset by a distance (such as offset distance O). In such embodiments, the attachment end may slot into the offset distance, retaining the eyelash between the first gripper, the second gripper, and the attachment end.

[0124] In block 1220, the first micro-robot and the second micro-robot are positioned to apply the eyelash. In some embodiments, both the first micro-robot and the second micro-robot move in a same direction at a same speed to maintain a same distance between them as the first micro-robot and the second micro-robot move towards the eye. This allows for the eyelash to remain retained until the first micro-robot and the second micro-robot are in position to apply the eyelash.

[0125] In block 1225, the gripper is retracted from the attachment end, releasing the eyelash. In some embodiments, the gripper and the attachment end remain stationary for a period of time before the gripper is retracted, to give time for adhesive to stick, cure, or otherwise apply the eyelash. In some embodiments, retracting the gripper includes moving the second micro-robot in the direction opposite of the attachment end.

[0126] In block 1230, the eyelash is applied.

[0127] FIG. 13 is another method 1300 of using a system for applying eyelashes, in accordance with the present technology. In some embodiments, the method 1300 is carried out by the systems (such as systems 1000, 2000, 4000, 9000) shown and described herein. In some embodiments, the method 1100 includes one or more micro-robots (such as microrobots 200, 200A, 200B, 400A, 400A-i, 400A-ii, 400B, 400B-i, 400B-ii, 900A, 900B, 900C, 900N, or a combination thereof), a flexible PCB substrate (such as flexible PCB substrate 105), one or more linear actuators (such as one or more linear actuators 115A, 115B, 115C . . . 115N), a motor base (such as motor base 120), and one or more eyelashes or eyelash clusters (such as one or more eyelash or eyelash clusters L1, L2, L3, L4 . . . . LN). In some embodiments, method 1300 further includes a camera system (such as one or more cameras 1005A, 1005B, 1005C), and a processor (such as processor 1010). In some embodiments, method 1300 further includes a system for applying eyelashes (such as system 2000). In some embodiments, the system for applying eyelashes includes a first micro-robot (such as first micro-robot 200A in FIGS. 2A-2B), having a first plurality of magnets (such as first plurality of magnets 205A-i, 205B-i, 205C-i . . . 205N-i) and a wire comb (such as wire comb 215) with an attachment end (such as attachment end 220), and a second micro-robot (such as second micro-robot 200B in FIGS. 2A-2B) having a second plurality of magnets (such as second plurality of magnets 205A-ii, 205B-ii, 205C-ii . . . 205N-ii), a tube (such as tube 210B), and a gripper (such as gripper 225).

[0128] In block 1305, the one or more micro-robots are monitored with the camera system. In some embodiments, the camera system is configured to capture stereo images (or image data) of the one or more micro-robots, the flexible PCB substrate, and/or the user (such as a user's eye, lash line, or the like).

[0129] In block 1310, the camera system transmits the image data to the processor. In some embodiments, the processor analyzes the image data to determine a location of the one or more micro-robots, a location of a user's eye/lash line, a density of a user's eyelashes, and a desired location for the one or more micro-robots.

[0130] In block 1315, the position of the first micro-robot and/or the second micro-robot is adjusted. The processor may direct the one or more micro-robots to the desired location, or to a secondary location close to the desired location, where if the flexible PCB substrate was adjusted, would result in the one or more micro-robots being in the desired location. For example, if the one or more micro-robots needed to be at a lash line of a first eye of the user, but the flexible PCB substrate was below the lash line of the user, the process may direct the one or more micro-robots to the secondary location below the lash line, with the intention of then adjusting the flexible PCB substrate to raise the one or more micro-robots to the lash line (i.e., the desired location). In some embodiments, adjusting the position of the first micro-robot and/or the second micro-robot includes adjusting the flexible PCB substrate by adjusting the height of at least one linear actuator of the plurality of linear actuators. In some embodiments, a pitch, yaw, roll, or combination thereof of the one or more micro-robots is adjusted with the flexible PCB substrate. In some embodiments, this is done by actuating the one or more linear actuators with the motor base to bend, flex, or otherwise adjust the flexible PCB substrate. In some embodiments, such as when the one or more micro-robots includes an applicator (such as such as applicator 210, attachment end 220, separating tip 440, or applicator 910), adjusting the flexible PCB substrate may also adjust an angle of attack of the applicator. As described herein, in some embodiments, each linear actuator of the plurality of linear actuators is configured to be controlled independently from one another.

[0131] FIG. 14 is a method 1400 of using an eyelash dispenser, in accordance with the present technology. In some embodiments, the method 1400 is carried out by the systems (such as systems 1000, 2000, 4000, 9000) shown and described herein. In some embodiments, the method 1400 includes one or more micro-robots (such as microrobots 200, 200A, 200B, 400A, 400A-i, 400A-ii, 400B, 400B-i, 400B-ii, 900A, 900B, 900C, 900N, or a combination thereof), a flexible PCB substrate (such as flexible PCB substrate 105), one or more linear actuators (such as one or more linear actuators 115A, 115B, 115C . . . 115N), a motor base (such as motor base 120), and one or more eyelashes or eyelash clusters (such as one or more eyelash or eyelash clusters L1, L2, L3, L4 . . . . LN). In some embodiments, method 1400 further includes a camera system (such as one or more cameras 1005A, 1005B, 1005C), and a processor (such as processor 1010). The method 1400 may also include an eyelash dispenser (such as eyelash dispenser 9000) having a body (such as body 905) and a plurality of slots (such as plurality of slots S1, S2, S3, S4 . . . . SN). The eyelash dispenser may retain the one or more micro-robots. In some embodiments, either the eyelash dispenser or the flexible PCB substrate may further include a drum pod (such as drum pod 930) pre-loaded with a plurality of eyelashes or eyelash clusters (such as plurality of eyelashes L1, L2, L3 . . . . LN).

[0132] In block 1405, the eyelash dispenser is inserted into an eyelash system (such as system for applying eyelashes 1000). In some embodiments, the eyelash dispenser has a body that can be placed into or otherwise retained by the eyelash system.

[0133] In block 1410, one or more micro-robots are released onto the flexible PCB substrate. In some embodiments, the one or more micro-robots are directed to the PCB substrate, such as with the processor in tandem with the camera system. In some embodiments, the one or more micro-robots are located in slots of the body of the dispenser, and may then slide or levitate onto the flexible PCB substrate.

[0134] In block 1415, the one or more micro-robots are positioned at a lash line of an eye. In some embodiments, the processor may direct the one or more micro-robots to the desired location, or to a secondary location close to the desired location, where if the flexible PCB substrate was adjusted, would result in the one or more micro-robots being in the desired location. For example, if the one or more micro-robots needed to be at a lash line of a first eye of the user, but the flexible PCB substrate was below the lash line of the user, the process may direct the one or more micro-robots to the secondary location below the lash line, with the intention of then adjusting the flexible PCB substrate to raise the one or more micro-robots to the lash line (i.e., the desired location). In some embodiments, adjusting the position of the first micro-robot and/or the second micro-robot includes adjusting the flexible PCB substrate by adjusting the height of at least one linear actuator of the plurality of linear actuators. In some embodiments, a pitch, yaw, roll, or combination thereof of the one or more micro-robots is adjusted with the flexible PCB substrate. In some embodiments, this is done by actuating the one or more linear actuators with the motor base to bend, flex, or otherwise adjust the flexible PCB substrate. In some embodiments, such as when the one or more micro-robots includes an applicator (such as such as applicator 210, attachment end 220, separating tip 440, or applicator 910), adjusting the flexible PCB substrate may also adjust an angle of attack of the applicator. In some embodiments, adjusting the position of the one or more micro-robots includes sliding or levitating the one or more micro-robots over the flexible PCB substrate.

[0135] In block 1420, the eyelash is applied.

[0136] FIG. 15 is another method 1500 of using an eyelash dispenser, in accordance with the present technology. In some embodiments, the method 1500 is carried out by the systems (such as systems 1000, 2000, 4000, 9000) shown and described herein. In some embodiments, the method 1500 includes one or more micro-robots (such as microrobots 200, 200A, 200B, 400A, 400A-i, 400A-ii, 400B, 400B-i, 400B-ii, 900A, 900B, 900C, 900N, or a combination thereof), a flexible PCB substrate (such as flexible PCB substrate 105), one or more linear actuators (such as one or more linear actuators 115A, 115B, 115C . . . 115N), a motor base (such as motor base 120), and one or more eyelashes or eyelash clusters (such as one or more eyelash or eyelash clusters L1, L2, L3, L4 . . . . LN). In some embodiments, method 1400 further includes a camera system (such as one or more cameras 1005A, 1005B, 1005C), and a processor (such as processor 1010). The method 1500 may also include an eyelash dispenser (such as eyelash dispenser 9000) having a body (such as body 905) and a plurality of slots (such as plurality of slots S1, S2, S3, S4 . . . . SN). The eyelash dispenser may retain the one or more micro-robots. In some embodiments, either the eyelash dispenser or the flexible PCB substrate may further include a drum pod (such as drum pod 930) pre-loaded with a plurality of eyelashes or eyelash clusters (such as plurality of eyelashes L1, L2, L3 . . . . LN). In some embodiments, the method 1500 occurs after the method 1400.

[0137] In block 1505, the one or more micro-robots are recalled to the drum pod.

[0138] In block 1510, the one or more micro-robots queue for the drum pod, to receive an eyelash or eyelash cluster from the drum pod.

[0139] In block 1515, a single eyelash or eyelash cluster is fed to each micro-robot of the one or more micro-robots that have queued. In some embodiments, a single eyelash or eyelash cluster is fed to a group of robots (such as system 2000).

[0140] In block 1520, the eyelash or eyelash cluster is applied.
