Abstract: A surgical robot, a control method, a system and a readable storage medium are disclosed. The surgical robot includes a manipulation terminal. The control method of the surgical robot includes: defining a safe zone and a warning boundary outside the safe zone, based on edge information of the surgical object; and based on a distance function between a current position of the manipulation terminal and the warning boundary, as well as on first feedback information from the manipulation terminal and second feedback information produced from an external environmental force, compensating drive information applied by the surgical robot to the manipulation terminal so that, when the manipulation terminal moves out of the safe zone, an impact of the external environmental force on driving of the manipulation terminal is reduced, eliminated or restricted.

Abstract: A flexible mechanical arm control method and a robot system. The control method comprises steps of: obtaining a total amount of angular displacement of a joint output end of the flexible mechanical arm (110) along a first direction when a load on the joint output end changes; driving the joint output end to move in a second direction according to the total amount of angular displacement, so that the joint output end returns to a position and posture before the load changes; the second direction is opposite to the first direction. According to the method, the position and posture of the joint output end can be maintained when the load on the joint output end of the flexible mechanical arm (110) changes, so as to facilitate a doctor to execute predetermined surgical operation in the fixed position and posture.

Abstract: The present disclosure provides a surgical robot including a control system, a force identification system, a robotic arm system and a navigation system, the robotic arm system including a robotic arm, a robotic arm terminal detachably connected to a trackable element. The navigation system acquires and provides a registration point of interest on an object to the robotic arm system. The robotic arm system controls movements of the robotic arm to drive the trackable element to move to the registration point of interest. The force identification system detects and provides a force applied to the robotic arm terminal to the control system. The control system determines whether the trackable element has moved to the registration point of interest on the object. The present disclosure also provides a method for bone registration of the surgical robot.
