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)

| | Obstacle detection : infrared sensor ??
|

Hey.. I don't know if this is a LegOS question, but here it goes... Is it possible to detect obstacles via the infrared sensor, before you bump into them ?? Like measuring reflection of infrared light or something... If it is... how ?? can anybody (...) (24 years ago, 24-Mar-01, to lugnet.robotics.rcx.legos)

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 (...)

Dear two, I like your program very much. I have three suggestions: 1. Give a progress indication when downloading or uploading, if possible. 2. Identify unsaved changes by an asterisk behind the filename in the titlebar. 3. Allow to copy from the (...) (24 years ago, 23-Mar-01, to lugnet.robotics.rcx.nqc)

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 (...)
