Abstract
A surgical robot includes a robot arm, an operation device that is operated by a user to perform an operation of the robot arm, an actuator that supplies a driving force to the robot arm, and hardware control logic or a processor that sets a magnitude of an operation reaction force a direction opposite to an operation direction of the operation device, and applies the operation reaction force having the magnitude set by the reaction force setter to the operation device. The magnitude of the operation reaction force is set based on change information about a change in the driving force supplied by the actuator and based on a conversion coefficient.
