The subjects of electro-pneumatics and vacuum technology are demonstrated clearly with the aid of fascinating models such as the pneumatic motor, color sorting robot for colored parts, ball obstacle course and pinball machine. The new, powerful and compact compressor guarantees a reliable supply of compressed air to the models. The electro- magnetic valves included allow remote control of the models with a PC. Contains 400 components (including compressor, miniature motor, 2x solenoid valves, optical color sensor, vacuum exhauster, 3x cylinders with spring, 2x photo-transistors, 2x lens tip lamps, and 11 fl ex-rails) for building 4 functional models. Also includes related instructional material on CD. Requires ROBO TX Controller, ROBO Pro Software and either Accu Set or Energy Set.
