Unless the project involves just opening or closing whatever, without
proportional control, the end product could be quite hilarious.  The
control for the project could quite easily be done using PICs  (google
for proportional + PIC) or any of the Atmel offerings. The expensive
part will be the  control valves, hydraulic cylinders, flow
regulators/dividers, motors, and pump. If you get stuck on any of the
parts give me a shout and I'll see if I can get samples.

Cheers.
