ABSTRACT:
A direct teaching type robot in which in the playback of the robot an electric power corresponding to a playback command is supplied to an electric motor from a servo driver so that the electric motor is driven to move a moving arm of the robot and in the teaching operation the moving arm is directly moved by an instructor to teach its movement to the robot includes breaking means provided in the servo driver for breaking a current generated by the electric motor when the electric motor is rotated in response to the teaching operation of the moving arm so as not to flow into the servo driver, whereby operation force by the instructor for moving the moving arm of the robot in the teaching can be reduced.
