(...) You might try disableing the FIFO (if it has one) in the serial port configuration. Depending on what other applications use the serial port, you will probably want to re-enable the FIFO when using those applications. Mike (25 years ago, 25-Mar-01, to lugnet.robotics.rcx)

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.

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 (...)

Whoa. Not entirely correct. You can do accurate positioning with pneumatics, it's just harder to do than with hydraulics, because you have to take air compressiblity and seal "stiction" into account if you want to hit an arbitrary position that's (...)
