Abstract
An industrial robot in which both a column which is pivotally mounted on a rotatable base member and a boom which is pivotally mounted on the upper end of the column are of hollow construction to provide a rigid lightweight structure capable of carrying substantial loads. The column is counterbalanced by a spring and the boom is counterbalanced by pneumatic cylinders on a movable carriage so that the major axes of the robot can be driven by relatively low energy driving sources. A simplified hand gear train is provided which is capable of carrying substantial loads and is easily serviced.
