I've been thinking of taking on a small side research project for a while... and I was wondering if I could get some suggestions for a small pnuematic pump (probably something that could supply about 10psi). I've been interested in the idea of 'soft' robotics for a while, and found George Whiteside's research at Harvard very compelling (http://gmwgroup.harvard.edu/techniques/index.php?topic=Soft%20Robotics
). I've got some information on the silicone casting process... but I'm a little new to pnuematics and don't really know where to start. I know the Whiteside research group also uses liquid pumping, but I think for the moment I'd like to stick to air pressure to inflate the silicone. Ideally, I'd like the pump to be able to be controlled via an arduino (to turn on/off) and potentially have a valve (solenoid) that could be opened/close via a microcontroller as well. Does anyone on here have any suggestions or places to start looking?
