What kind of Pump do I need for Hydraulic movement in an animatronic puppet.?
I want to build a Hydraulic-based animated figure. Heck, I want to just build a small frame with a single moving piece and actuate it with Hydraulics.
The trouble is, information on Hydraulics for hobby robotics/Animatronics on the web is pretty thin. I've found quite a bit of Servo related stuff, a little bit of Pneumatic stuff, but so far I haven't had luck finding a good tutorial on automated Hydraulic animation. Truthfully, I need information on the whole picture, but I understand the basics of getting a cylinder to move and how to set that up.
I know how to do it with Pnuematics. Air is not quite power/accurate enough for what I want to do. I want Hydraulics.
