ABSTRACT:
An industrial robot's articulate device comprises: a first arm; a second arm rotatably connected to the first arm; an electric motor for rotating the second arm; a transmission shaft rotatably supported by the first arm for transmitting the output of the electric motor to the second arm; and a detecting mechanism for detecting the position of the second arm with respect to the first arm. The detecting mechanism includes a dog secured to the transmission shaft, a swing lever swingably coupled to the first arm to pose in alternative postures according to the direction of rotation of the dog and a detector for detecting the alternative postures of the swing lever. The detector is constituted by a pair of limit switches, which are provided on both sides of the swing lever to detect the alternative postures thereof.
