Interesting project.
Will your car have a pneumatic engine?
Pneumatic steering?
The large pump can run the engine with no externally controlled switches.
Steering on the other hand would require control of two switches.
Both pistons expanded could turn right. Both pistons contracted could turn
left. One expanded and one contracted would go straight ahead.

| Hi , According to the (URL) a mini-compressor (using a single small pump) is actually more efficient than using double pump. It said more efficient, but not generate higher output though, correct??? (URL) produces a more persuasive test. However, (...) (20 years ago, 9-Jun-04, to lugnet.robotics.rcx.legos, lugnet.technic)
