Abstract
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.

A 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 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.
A robotic medical system comprising:
- a brake to lock movement of at least a portion of the robotic medical system;
- and
- an actuator to selectively engage or disengage the brake, the actuator including 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.
A 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 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 joint;
- an actuator to selectively engage or disengage the brake;
- and
- wherein the brake comprises:
- a cup having a conical inner perimeter;
- and
- a cone for receiving the conical inner perimeter of the cup when the brake is engaged,
- wherein engaging of the brake includes moving the conical inner perimeter of the cup into contact with the cone.
