An example rotational joint assembly for a robotic medical system, the rotational joint assembly comprising at least one arm segment and a rotational joint provided at one end of the arm segment. The rotational joint is to allow the arm segment to rotate about a rotational axis. The rotational joint comprising a brake to lock rotation of the arm segment at the rotational joint and an actuator to selectively engage or disengage the brake. The actuator comprising a cam having two stable regions separated by two transition regions, the two stable regions comprising a first stable region corresponding to engagement of the brake and a second stable region corresponding to disengagement of the brake.

Disclosed herein is a joint unit including two facing gears that include respective two bevel gear members that face each other, and an intermediate gear that has a bevel gear member meshing with both the two bevel gear members. One of the two facing gears and the intermediate gear includes a first member including an inner circumferential portion of the bevel gear member of the one of the two facing gears and the intermediate gear; a second member including an outer circumferential portion of the bevel gear member of the one of the two facing gears and the intermediate gear; and a resilient member attached to one of the first member and the second member for normally urging the other of the first member and the second member to move in a direction along the directions of rotation of the one of the two facing gears and the intermediate gear.

A linear joint includes a motor assembly includes a rotating shaft for outputting motion; a transmission mechanism including a screw and a nut threadedly connected to the screw, the nut being coaxial with respect to and securely connected to the rotating shaft so as to be rotatable together with the rotating shaft; and a rod connected to a first end of the screw so as to move together with the screw along a lengthwise direction of the screw.

A non-destructive inspection system is presented. The non-destructive inspection system comprises a robotic end effector having an extendable actuator and a flange-mounted roller containing an ultrasonic sensor, the flange-mounted roller connected to the extendable actuator by a pivot connection, the extendable actuator configured to extend the flange-mounted roller until the flange-mounted roller contacts an inspection surface.

A robot cable-assembly management structure including a first fixing member that fixes, to a turning drum, a cable assembly extending beside the turning drum in a front-rear direction, and a second fixing member that fixes, to a side surface of the arm, the cable assembly extending to a front side of the first fixing member, at a position closer to a distal end of the arm than the second axis, where a movable portion of the cable assembly located between the first fixing member and the second fixing member is provided with a necessary length of allowance and is twisted in one direction, so that the movable portion is bent in a direction away from the side surface of the arm when the arm swings to a rear swing end is displaced toward the side surface of the arm as the arm swings toward a front swing end.

A device includes a tube and a sleeve configured to at least partially encircle a portion the tube along its length. The tube is flexible and airtight and defines a longitudinal axis along a center of the tube, and is configured to bend along the longitudinal axis upon at least partial evacuation of the tube to form a joint. The joint defines a joint angle relative to the longitudinal axis, thereby approximating a revolute joint with torsional stiffness. Actuating a joint includes partially evacuating a flexible tube defining a longitudinal axis, thereby forming a bend in the tube at an angle with respect to the longitudinal axis at a perimeter of a rigid sleeve at least partially encircling the tube, and restoring a neutral pressure to the tube, thereby removing the bend in the tube.

A roll joint is provided. The roll joint may comprise: a first body; a second body disposed opposite to and spaced apart from the first body; a connection body which is disposed between the first body and the second body and is not in contact with the first body and the second body; and a connection wire member which connects the first body, the second body, and the connection body to one another so as to make a tensegrity structure.

The invention relates to a handling device for handling objects, including a base unit which extends overall in an elongate manner along a base axis from a first end to a second end, wherein a flange portion is arranged at the first end for fastening the handling device to a robot arm and wherein a pivot unit having a pivot portion is arranged at the second end, wherein the pivot portion is mounted so as to be pivotable about a pivot axis by a pivot joint, wherein the base unit has a pneumatic cylinder which is designed to pivot the pivot portion about the pivot axis, and including a couplable or coupled, pneumatically operated end effector for gripping an object.

The present invention discloses a shafting structure of an integrated joint for a collaborative robot, wherein two ends of a long input shaft are respectively a motor rear end and a flexspline end, and a harmonic gear drive is installed on the flexspline end; the motor rear end is coaxially provided with a motor rear end bearing set, a motor rear end inner race pressing ring, a motor rear end outer race pressing ring, a motor rear end outer race seat and a motor rear end angle encoder mounting seat; and the flexspline end is provided coaxially with a flexspline end bearing set, a flexspline end inner race pressing ring and the harmonic gear drive. In the present invention high-precision position feedback and control can be realized.

A grasping device includes: a grasping unit configured to grasp a container filled with liquid; a tilting unit configured to at least tilt the container in a state where the grasping unit grasps the container; and a maker installed at a part tilting in synchronism with the container when the container tilts and configured to move in conjunction with movement of the container.
