Abstract
Working system for an application of force onto a workpiece, with a pneumatic actuator having an actuator housing designed to be fixed to a manipulator and a moveable element designed to couple an end effector and movably received on the actuator housing, and with a controller having a valve arrangement for a compressed air supply to the pneumatic actuator, has a position sensor system for determining a spatial position of the pneumatic actuator and for providing position-dependent electrical position sensor signals, and a processing system for processing the position sensor signals and for providing control signals to the valve arrangement, the processing system being designed for controlling a pneumatic supply to the pneumatic actuator as a function of the position sensor signals.

A working system for an application of force onto a workpiece, with a pneumatic actuator comprising an actuator housing to be fixed to a manipulator, wherein a moveable element is movably received in the actuator housing, the moveable element being moveable along a movement axis;
- with a controller comprising a valve arrangement for supplying compressed air to the pneumatic actuator, further comprising a position sensor system for determining a spatial position of the pneumatic actuator and for providing position-dependent electrical position sensor signals, and further comprising a processing system connected with the position sensor system, said processing system being configured to process the position sensor signals and to provide control signals to the valve arrangement to control a pneumatic supply to the pneumatic actuator as a function of the spatial position of the movement axis, the spatial position being calculated based on the position sensor signals.
A manipulator selected from the group consisting of:
- tripod, Scara robot, a multi-axis robot, the manipulator comprising a working system for an application of force onto a workpiece, with a pneumatic actuator comprising an actuator housing to be fixed to a manipulator, wherein a moveable element is movably received in the actuator housing and is moveable along a movement axis;
- with a controller comprising a valve arrangement for supplying compressed air to the pneumatic actuator, further comprising a position sensor system for determining a spatial position of the pneumatic actuator and for providing position-dependent electrical position sensor signals, and further comprising a processing system connected with the position sensor system, which processing system processes the position sensor signals and provides control signals to the valve arrangement to control a pneumatic supply to the pneumatic actuator as a function of the spatial position of the movement axis represented by the position sensor signals.
