Limiting joint velocity of surgical robotic system with common limit
A recently granted patent (Publication Number: US11999062B2) discloses a method for limiting joint velocity in a surgical robotic system. The method involves obtaining joint states for a group of joints, determining permitted ranges of motion for each joint, deriving joint velocity limits, selecting a common joint velocity limit for the group, calculating drive signals to actuate the joints within the velocity limit, and controlling the arm accordingly. The system aims to ensure safe and controlled movement of the robotic arm during surgical procedures by restricting joint velocities based on predetermined limits.
Furthermore, the patent includes additional claims related to the configuration of joints proximal to the base of the arm, determining joint velocity limits based on angular distances and deceleration rates, providing feedback to users when velocity limits are exceeded, and utilizing a joint velocity limiting system and computer-readable storage medium to implement the method. By incorporating these features, the patented technology enhances the safety and precision of surgical robotic systems by effectively managing joint velocities to prevent unintended movements or potential risks during procedures. This innovation represents a significant advancement in the field of robotic surgery, offering improved control and accuracy in complex surgical tasks.
