Claude,
Real nice project!
I am interested in more details concerning the grabber hand. The page says
it is pneumatics, but there don't seem to be many details. Any info on this
part of the arm would be great.
Thanks,
Jona

| The pneumatic part of the project has five sections: - air-pump --> we use Ralph Hempel's well known two-pistons pump - air-direction switch --> J.Brown has solved that problem geniously, so we use this (URL) air-pressure-sensor --> again we use J.
