Abstract
In an industrial robot having a plurality of arms, each arm is coupled with other elements such as a mounting base, another arm, a robotic hand, and revolved by a motion of a revolving joint. A motor for moving the revolving joint, an encoder for sensing a rotation angle of a drive shaft of the motor, and a control circuit for controlling the driving of the motor are provided on the same arm. A signal cable for transmitting a sensing signal of the encoder to the control circuit is terminated at the control circuit on the same arm. There is no need to align the signal cable from the encoder to a main control circuit provided in the mounting base.
