Re: Robot Speeds

I'm going to have to clarify that speed. 13 fps (...calculated, more like 10-11), but that was only parrallel to the wheels. If we drove 45 degrees across our wheels (straight) we would go about 7-8fps.... and then we put our arm on and got scared of going that fast.

Oh and the expanding module thing...hmmm i think i have an inventor pic somewhere.

found it... an old one though.

also, not in this pic is the driving mechanism for this expansion. you can see it here: http://www.chiefdelphi.com/forums/sh...highlight=1002

There was a piston involved also, but we don't like to talk about it.

Re: Robot Speeds

Approx. 4 fps in low, and I think about 12 fps in high. I don't have the numbers here with me. Single CIM with a DeWalt each side. The drivers were afraid to drive it in anything other than low, so we never put the servos on to be able to shift, just left it in low, due to a lack of practice time. We're going to set it up to shift this fall.
