This is a good site indeed, but is there anybody who actually works on big robots? It's ridiculously easy to operate pesky stepper motors using a ULN2003 via a parallel port, but I'd be grateful if somebody actually worked on something hydraulic, like a gripper arm actuated by hydraulic pressure, etc.... I am working on a fire fighting system, but din't get time to work on it, shall start it soon.
