I have to use a small air receiver to build a wheeled vehicle that will be operated by compressed air. The goal is to build the vehicle that can travel in a straight line, towing a standard load (about 3-4 lbs), on one charge of 90 psi in the receiver.The volume of the receiver is 16 cu in. I cant use any air or electric motors. But I can use cylinders.
What are some good ideas to accomplish this?
I was thinking of using a crank shaft mechanism with the cylinder. How can I make the most out of 90 psi of pressure.
