Perhaps TLG should be meeting companies that produce valves of the same quality as those mentioned. It also sounds like the timing belt used for the test bed could be replaced or reinforced even more. -- Cheers ... Geoffrey Hyde "Xanthra47" (...)

Yep, and if you combine those high-speed, high-precision pressure regulators with low stiction cylinders and a fast PID controller you can get even better accuracy and repeatability. When I was working for an encoder company, I scavenged some parts (...) (24 years ago, 25-Mar-01, to lugnet.build, lugnet.general, lugnet.technic, lugnet.robotics.rcx)

Hi I did some 'research' in this area about three years ago for the control of a pneumatic robot arm. It was quite simple positional control ie position the piston at any point in the cylinders stroke and hold it there. The controller was just a PC (...)
