A torque generation system may include a torque generator, transmission mechanism, frictional interface, squeezer plate, output plate, piezoelectric actuator, and controller. The system may transition between a zero-torque condition, where the squeezer plate is disengaged, and a torque generation condition, where the controller activates the actuator to engage the frictional interface between various operational modes, which are implemented as various personalized modes. This engagement allows the input torque generated by the torque generator to be transmitted through the frictional interface to the output plate, producing an output torque.

Abstract: Pressure disturbances in a pneumatic robotic force control device—including force overshoot upon initial contact between a robotic tool and a workpiece—are mitigated by increasing the mass air flow in or out of a pneumatic chamber via one or more force overshoot mitigation air passages formed in the robotic force control device. The force overshoot mitigation air passages may connect the two chambers in air flow relationship, or may allow air flow from a chamber to the exterior. The force overshoot mitigation air passages may have a static or variable effective area. The optimal area may be calculated based on measured flow rates and pressures during typical use cases.
