Problems

• 1. Design a model of human arm and hand using
  pneumatic technology.
• 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
• 3. Experiment with different software strategies
  to control valves to allow for very fast action
  with high pressures, this is not trivial.
