A robot leg comprises at least two phalanges (1, 2) connected to each other by articulated joint (4). The robotic leg further comprises the electric motor (6A) with the shaft (61A), the cardan mechanism (7A) and the rod (8A), wherein the electric motor (6A) with the shaft (61A) is arranged in the first phalange (1), the cardan mechanism (7A) comprises the driving carrier (71A), the driven carrier (72A), the cross (73A) and the fork (74A). The driving carrier (71A) is connected via the shaft (61A) of the electric motor (6A) with the electric motor (6A), so that the driving carrier (71A) of the cardan mechanism (7A) is driven by the electric motor (6A), the driven carrier (72A) is connected with the first phalange (1), the cross (73A) is arranged between the driving carrier (71A) and the driven carrier (72A), the cross (73A) being rotatably connected with the driving carrier (71A) and rotatably connected with the driven carrier (72A), the fork (74A) being rotatably connected with the cross (73A). The rod (8A) is connected at one end thereof with the fork (74A), and at the other end thereof with the second phalange (2) by means of articulated joint (4A). The coupling of the electric motor (6A) with the cardan mechanism (7A) and with the rod (8A) connected with the second phalange (2) ensures the transmission of the rotational movement of the electric motor (6A) to the swinging movement of the fork (74A) in the longitudinal plane with the axis of rotation at the centre of the cross (73A), and thus transferring the swinging motion of the fork (74A) to the linear motion of the rod (8A), which ensures the swinging motion of the second leg phalange (2) about the axis of articulated joint (4).

A robot arm includes a plurality of links and a plurality of joints connecting the links for adjustment relative to one another. At least a first link has a first bearing pin, a second bearing pin located opposite the first bearing pin, and a second link connected in an articulated manner to the first link by one of the joints has a first bearing flange on which the first bearing pin of the first link is rotatably mounted, and has a second bearing flange on which the second bearing pin of the first is rotatably mounted. The first bearing flange of the second link has a circumferentially closed recess in which the first bearing pin of the first link is received, and the second bearing flange of the second link has a circumferentially open recess in which the second bearing pin of the first link is received. An opening in the circumferentially open recess has an opening width that is greater than the width of the second bearing pin of the first link, and the second bearing flange has securing structure with which the second bearing of the first link is secured to the circumferentially open recess of the second bearing flange.

The present disclosure provides a robot arm for minimally invasive surgery and a method of controlling the same and is directed to providing a surgical robot arm in which a remote center of motion (RCM) control is implemented through an electronic control so that an overall size of an instrument is reduced and a configuration is simplified, thereby increasing space efficiency and preventing collisions between robot arms.

An apparatus includes a platform configured to traverse a stationary base along a motion path; a drive coupled to the platform; and a movable arm assembly. The movable arm assembly includes a pivoting base connected to the drive, first and second linkages connected to the pivoting base, each linkage having links connected via rotary joints and each link having at least one end-effector. The platform is configured to traverse the stationary base along a motion path in two opposing directions and the drive and the movable arm assembly are configured to cause independent and simultaneous movement and transfer of substrates from at least one of a first substrate holding area, a second substrate holding area, a third substrate holding area, or a fourth substrate holding area into or from a respective substrate workstation.

Embodiments of the present invention provide methods and systems to analyze wearable technology. A robot with snake assembly works in conjunction with a server in order to simulate the locomotive actions of appendages and to concomitantly determine the response of wearable technology devices, which are attached to the snake robot assembly, to the simulated locomotive actions.

A guiding apparatus for remote medical treatments includes a first pivoting link pivotally connected to a pivot shaft, a second pivoting link pivotally connected to the first pivoting link, a driver pulley member capable of fixing the first pivoting link and the second pivoting link to each other through screw fastening, a driven pulley member capable of fixing the first pivoting link to the pivot shaft through screw fastening, and a locking wire connected to the driver pulley member and the driven pulley member to transmit a rotational force from the driver pulley member to the driven pulley member. As the driver pulley member rotates, the driven pulley member rotates together, so that the fixing of the first pivoting link and the second pivoting link to each other and the fixing of the first pivoting link to the pivot shaft is accomplished simultaneously.

A rotary actuation mechanism comprising an actuator having a body, and a slider movable on a linear path relative to the body. A first linkage can be pivotally coupled to the body at a first pivot having a first axis. A second linkage can be pivotally coupled to the slider at a second pivot having a second axis, and pivotally coupled to the first linkage at a third pivot. A length of the first linkage between the first pivot and the third pivot can be equal to a length of the second linkage between the second pivot and the third pivot. The slider can be movable to position the second axis in a collinear relationship with the first axis. The rotary actuation mechanism can include an anti-singularity device to constrain movement of the body when the first axis and the second axis are in the collinear relationship.

A robot for a linear transport system includes a carriage guide rail and first and second XY tables, each with first and second carriages arranged to move independently on the carriage guide rail, and first and second linear guides, each having first and second guide elements which can be moved relative to one another and are configured with an angular offset. The first guide elements of the first and second linear guides are connected via a support structure. The second guide elements of the first and second linear guides are connected to the first and second carriages.
