pneumatic robot

I am planning to build pneumatic robot.
What I need is proportional servo valve suitable for this purpose.
Does anybody has seen such thing on the web?

You've kinda hit upon the reason why there are few pneumatic robots. There are no viable valves. Proportional servo valves are big, expensive, and power hungry. Dynalloy

uses nitinol to make a proportional valve. It's small, quiet, and less expensive than comparable solenoid or servo valves ($8 when ordered in bulk), but it's still difficult to drive and a huge power hog. Plus Dynalloy only offers it as a demonstration product, so you have to buy tons of them for the price per unit to become reasonable.
Maybe in a decade we'll see some improvements with polymers that'll solve the problems inherent with SMAs. But for now robotic pneumatics is a bleak and cumbersome field.

On the Motors and Muscles page you will find Merlin Systems Corp and several other suppliers for pneumatic "muscles".
