摘要： An articulated industrial robot has an articulated horizontal arm assembly which includes horizontal arms (20), a vertically movable shaft (20) mounted on the extremity of the horizontal arm assembly, and a motor for driving the vertically movable shaft. When directly teaching motions to the vertically movable shaft through a direct teaching operation by an operator, the current control unit of a motor control unit for driving the motor for driving the vertically movable shaft is disconnected from a signal line connected to a robot control unit, and a torque calculating circuit is provided for deciding a motor torque corresponding to the sum of the weight of the vertically movable shaft and the respective variable weights of an end effector attached to the lower end of the vertically movable shaft. A workpiece held by the end effector is connected to the current control unit to compensate the load torque of the vertically movable shaft with the torque of the motor so that the operator is able to carry out the direct teaching operation while substantially no load is imposed on the operator.
