A robotic gripper may be configured to dexterously manipulate an article. The robotic gripper may include two or more fingers containing one or more rotatable contacts each. The rotatable contact may transition between a rotation mode and a braking mode such that the contacts are free to rotate in the rotation mode and are prevented from being rotated in the braking mode. In some instances, the robotic gripper may make contact with the article via the contact pads. Thus, the robotic gripper may dexterously manipulate the article via the contact pads and brake.

The present application provides a brake apparatus for a rotating component, a robot joint and a robot including the same.

Each of the plurality of brake ends is provided with a second magnet. A side of the first magnet facing the, brake component is configured to have same polarity as sides of the second magnets facing the locking component. A distance from the first magnet to a rotary axis of the rotating component is substantially the same as distances from the second magnets to the rotary axis of the rotating component.

A robotic medical system can include a motorized arm that is supported by a column of the system. The robotic arm can be operated by rotating a link of the motorized arm by actuating an actuator to drive rotation of a rotary joint. A brake can then be applied to the rotary joint to stop rotation of the link. The arm can also include an arbor that can be actuated to increase a torsional stiffness of the rotary joint.

A brake apparatus, a motor, and a robot. The brake apparatus includes a first ring connected to a shaft and being rotatable together with the shaft. Wherein the first ring includes a first set of magnets. The brake apparatus also includes a second ring, which is spaced apart from the first ring by a gap, and includes a second set of magnets, the second set of magnets being magnetically coupled to the first set of magnets such that the second ring tends to rotate along with the first ring. The brake apparatus includes a first member connected to the second ring and being rotatable together with the second ring; and a second member being switchable between a first state and a second state. An impact force will not be transmitted to the shaft when the shaft is rotating, and thus a damping effect can be achieved during braking.

A control apparatus includes driving means for rotationally driving a predetermined mechanism, braking means for braking the driving means by pressing a pressing unit against a rotation unit of the driving means, and control means for, in order to change rotation position of the predetermined mechanism, controlling the driving means in a braking release period in which the pressing unit is returned to a predetermined position to temporarily maintain the rotation position of the predetermined mechanism, and then driving the predetermined mechanism to thereby change the rotation position. The control apparatus performs at least one of notification to the user, braking of the predetermined mechanism, and stopping of the driving means when a command time for the driving means at the time of temporarily maintaining the rotation position of the predetermined mechanism is longer than or equal to a predetermined time.

Systems and methods for instrument disturbance compensation include a computer-assisted device. The computer-assisted device includes an articulated arm having a plurality of joints and a control unit coupled to the articulated arm. The control unit is configured to detect a disturbance to the articulated arm caused by a release of one or more brakes of the plurality of joints and maintain a position of a point of interest associated with the articulated arm by compensating for the disturbance using one or more joints of the plurality of joints. In some embodiments, the point of interest is a tip of an end effector of the articulated arm. In some embodiments, the control unit is configured to determine a predicted motion for the point of interest based on the disturbance and send a drive command to move the point of interest in a direction opposite to the predicted motion.
