Air Compressor Small one in the lab n 20 gallon tank n Connected via flexible hose n Purchased from Grainger n

Other Parts n Control box – Tap Plastics n Hoses and tubes – Wacky Willies, ? n Connectors – Home Depot, A 1 hose & coupling

Problems 1. Design a model of human arm and hand using pneumatic technology. n 2. In Wacky Willy and in Boeing Surplus store in Seatlle find pneumatic valves and actuators that you can use in building a big battlebot arm n 3. Experiment with different software strategies to control valves to allow for very fast action with high pressures, this is not trivial. n
