Robotic Tool Holder with Passive Compliance

A compliance mechanism for holding a robotic finishing tool implements passive force control and compliance using one or more double-acting pneumatic pistons. A desired application force is set and maintained by controlling pneumatic pressure in chambers both fore and aft of the one or more double-acting pneumatic pistons. The pressures in the fore and aft chambers are dynamically controlled, e.g., in response to changes in spatial orientation of the robot arm and tool, to maintain a desired compliance force applied by the robotic finishing tool to a workpiece. An external regulator maintains the fore and aft chamber pressures, for a given spatial orientation, throughout the holder's range of compliance motion. The compliance mechanism includes a plurality of piston bores; the number of active pistons may be adjusted for a given operation, e.g., in response to the finishing tool weight.
