Dr. C. S. Soh the famous LEGO pneumatic engine enthuesiast threw down a friendly challenge that we need a pneumatic biped made from small pneumatic pistons. It took up the challenge and met the challenge after less that four hours of building time.

This is my penumatic AND gate invention. It is a successor to my pneumatic OR gate invention. It is much simpler than the OR gate. This simplicity allows it to operate faster, more reliably and at lower pressures than the OR gate.

Caterpillar moves by expanding and contracting pistons in a coordinated fashion. This moves the feet forward one at a time. It moves forward very slowly.

On a flight to Boston, I figured out an important graphical technique for designing complex pneumatic circuits. I created asynchropillar. After asychropillar worked so well I got the idea to make an inchworm that used a traveling wave propagating down the body to walk.
