ABSTRACT:
An industrial robot assembly comprises a support body including a station portion and a vertically translatable portion. A tapered arm member is mounted to the translatable portion of the support for rotation about a first vertically oriented axis, and an angle lever is mounted to the tapered arm member at a point spaced from the first axis for rotation about a second axis parallel to and spaced from the first axis. A first electric motor is operatively connected to the arm member for rotating that member about the first axis, while a second electric motor is operatively connected to the angle lever for rotating that lever about the second axis. A translatable and rotatable component for carrying grippers or another workpiece manipulating element is mounted to the angle lever at a point spaced from the second axis. A third electric motor and a lifting drive are operatively coupled to the holder component for translating the component and for rotating that component about a third axis, respectively. The electric motors are all mounted to the arm member, the lifting device being mounted to the angle lever.
