An item with fibers may be picked up and placed using a tool head with hooks that engage the fibers. The tool head may comprise at least one hook portion and at least one contact surface adjacent to the hook portion. The hooks that engage the fibers may extend from the hook portion. The tool head may be actuatable between at least a first configuration that permits the hooks to engage the fibers and a second configuration that does not permit the hooks to engage the fibers. An item may be picked up at a starting location with a tool head in the first configuration and placed at a placement location by moving the tool head and then actuating the tool head to the second configuration.

Gripper pads are provided for use, augmentation or retrofitting in a robot manipulator. The gripper pads distinguish a dry adhesive layer with dry adhesive wedges that would interface with an object that is desired to be manipulated. The plurality of dry adhesive wedges is organized in a pattern such that the pattern has at least two different orientations for the direction of the plurality of wedges. The gripper pads further distinguish a sensor array underneath the dry adhesive layer. The data obtained from the sensor array provides an estimate of the shape and size of the contact between the gripper pad and the object when the dry adhesive layer is in contact with the object.

The present disclosure discloses a fibrillar, directional adhesive assembly, a gripper, and a robot including a gripper. In one embodiment, the fibrillar, directional adhesive assembly includes a carriage, a layer of fibrillar, directional adhesive, and at least one load component. The carriage may have a first lateral side and a second lateral side adjacent to the first lateral side and the at least one load component may connect the layer of fibrillar, directional adhesive to the first lateral side and the second lateral side. The load component may be capable of loading shear force from the carriage to the layer of fibrillar, directional adhesive along a first direction and a second direction substantially perpendicular to the first direction.

An item with fibers may be picked up and placed using a tool head with hooks that engage the fibers. The tool head may comprise at least one hook portion and at least one contact surface adjacent to the hook portion. The hooks that engage the fibers may extend from the hook portion. The tool head may be actuatable between at least a first configuration that permits the hooks to engage the fibers and a second configuration that does not permit the hooks to engage the fibers. An item may be picked up at a starting location with a tool head in the first configuration and placed at a placement location by moving the tool head and then actuating the tool head to the second configuration.

An object retrieval device is disclosed. The retrieval device includes a retrieval end, a joint, and an extension arm. The retrieval end includes an adhesive portion and an arm portion. The arm portion includes a set of protrusions and adhesive portion includes surface segmentation. The joint is configured to pivot. The extension arm includes a first set of protrusions disposed at a first end of the extension arm. The first end of the extension arm is couplable to the arm portion of the retrieval end such that the first set of protrusions disposed on the extension arm align with the set of protrusions disposed on the arm portion of the retrieval end to form ridges.

An affordance is disclosed which allows a robot system to pick an expanded range of items using a single type of end effector, without requiring the use of different end effectors. The affordance includes a first layer and a second layer. The first layer is arranged to be grasped by an end effector of the robot system and the second layer is arranged to adhere to the item. A system having an affordance and a robot system with an end effector arranged to grasp at least one item from storage by way of the affordance is also disclosed.

An adhesive apparatus with an electrostatic adhesive including a microstructured adhesive disposed over an electrode and/or a piezoelectric element. The adhesive can be added to any robotic gripper, such as a gripper finger formed of a flexible material and including a grip surface. The electrode and/or a piezoelectric element can be used for applying an electrostatic field and/or ultrasonic vibration, configured for cleaning the microstructured adhesive, releasing the adhesive, and/or sensing a load on the adhesive apparatus.

An apparatus and a method for assembling optical module. The apparatus includes: a plurality of fixtures, an alignment mechanism, a power supply, a spectroscopic prism with a light incident surface close to the plurality of optical modules to be aligned, a first image collecting means close to a first light emitting surface of the spectroscopic prism and a second image collecting means with a second light emitting surface of the spectroscopic prism; the controller is configured to determine a light spot that does not meet a quality requirement according to the positions and/or sizes of the plurality of imaging light spots, and generate a corresponding aligning instruction, and determine a to-be-assembled lens corresponding to the light spot that does not meet requirements according to a correspondence between a to-be-assembled lens and the light spot, and output the aligning instruction to an alignment mechanism to adjust a position of the lens.

A gripper system is provided that includes first and second linear carriages and first and second gecko adhesive patches. The gecko adhesive patches may have first and second surfaces, and a thin rigid backing may be attached to the second surface of the gecko adhesive patches. At least one layer of non-stretchable, flexible film may be glued to the thin rigid backing and a thick rigid backing may be glued to the film. The gripper system may further include a loading film. In other embodiments, the gripper system may include first and second pluralities of support tendons, which may connect the gecko adhesive patches to the carriages.

The present invention provides an automated system and method for construction and assembly of walls, floors and ceilings. Said system comprises at least one robotic arm, at least one material gripper tool, at least one sliding, rising and rotating system, and tongue-and-groove interconnection elements.
