Abstract
Provided is a robot system that can accurately sense contact between an arm of a robot or an instrument attached to the arm and another object. The robot system includes: a robot main bodyand a robot control unit, the robot main bodyincluding: a motor; a deceleration deviceconnected to a motor shaftof the motor; an armconnected to an output shaftof the deceleration device; a motor shaft-side angular sensorcapable of detecting an angle of rotation of the motor shaftof the motor; and an output shaft-side angular sensorcapable of detecting an angle of rotation of the output shaftof the deceleration device, and the robot control unitbeing configured to detect a contact state between the armor an instrument attached to the armand another object, based on a motor shaft-side rotation angle detected by the motor shaft-side angular sensor, an output shaft-side rotation angle detected by the output-side angular sensor, and an angular sensor misalignment correction value for the motor shaft-side angular sensorand the output shaft-side angular sensor
