HEX565 is a six legged pneumatic walker, also called a hexapod. Each leg has two pistons: one to lift and drop the leg, and the other to move the leg forward and back. HEX565 always has at least 5 feet on the ground at a time. It starts with all 6 feet back and on the ground. It then lifts...

After many overly complex failed efforts, I have made a pneumatic biped. The walking mechanism is completely automatic. Just apply air pressure. It can only walk forwards. No turning.

This invetion is an electro-pneumatic adding/subtracting machine. It uses pneumatics to do the arithmetic, and electricity/motors to feed bits into the pneumatics, and touch sensors to read the results from the pneumatics. Why build a pneumatic adding machine when we can make the RCX do the math much more easily and a lot faster? Good question!...

I was invited by Syngress to join a team to create a "LEGO Mindstorms Masters" book, where we got to build whatever creations we want without restrictions to a particular set. We got to describe the science behind the design of the robots in as much detail as we wanted.
