Re: Robot Pit Lift
Guys,
I have to put a big caution here. Pneumatics operate like right now, while hydraulics can have some control. (It's all in the valves) I would caution against using something that you can't stop once it starts. I saw a team a few years ago that had a pneumatic actuator on each wheel. When they hit the button, the whole frame and robot jumped up two feet. Knocked one of their pit guys over it was so fast. When a hose popped off and dumped the robot on the floor, they finally stopped using it.
As to using a dimmer, those are only designed for lighting at 120 volts AC and won't work at all on 12 volts DC. A variable speed control from a DeWalt drill (if you are using the NBD trannys) might work for each driven wheel. A foot operated pump up platform is a great idea. Anything that you can do to get the robot up to working height will save your back in the pit as long as you can get it down to where the robot fits through the doors.
