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. | InventorAssigneeApplicationNo. 06/612352 filed on 05/21/1984US Classes:414/735, Grab has swinging movement in plural planes901/15, Jointed arm901/21, Flaccid drive element901/22, Fluid motor901/26, Including bevel gear901/29WristField of Search901/15, Jointed arm901/21, Flaccid drive element901/22, Fluid motor901/26Including bevel gearExaminersPrimary: Spar, Robert J.Assistant: Smith, P.
