Pneumatic

Hand

 Computer controlled pneumatics

 Project components:

• Solenoid valves
• Air-muscles
• Air compressor

Solenoid Valves

 Electromechanical

device

 Air in

 Air out

 Purchased from

Mead Fluid

Components

Name: AM- 01 Length: 150mm Diameter: 12mm Load pulled at 3.5 bars: 3 Kilos Load pulled at 50 PSI: 6.5 lbs 25% Contraction with load of: 3 lbs Airmuscle: Small

Airmuscle: Medium  Name: AM- 02  Length: 210mm  Diameter: 20mm  Load pulled at 3. bars: 20 Kilos  Load pulled at 50 PSI: 45 lbs  25% Contraction with load of: 25 lbs

Air Compressor

 Small one in the lab

 20 gallon tank

 Connected via flexible hose

 Purchased from Grainger

Other Parts

 Control box

• Tap Plastics

 Hoses and tubes

• Wacky Willies,?

 Connectors

• Home Depot, A1 hose & coupling

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.
