The control unit is preferably performed during the robot arm moves at equal speed and the force sense when the amplitude less than the threshold value of the detection sensor initialization force sensor.
The present invention provides a robot, a robot controller and a robot system. The robot includes a robot arm of the present invention, a force sensor, and the work process of the robot arm control unit for controlling, the control unit moves the robot arm speed and the like to initialize force sensor. Further, the control unit is preferably performed during the robot arm moves at equal speed and the force sense when the amplitude less than the threshold value of the detection sensor initialization force sensor.
