Re: How much Bridge Space does your robot need?

Quote:
=Swampdude;1135220]Good points made. We are currently just under 100lbs, and around 123 with bumpers and battery. So we figured a nominal 145 lb bot needed to have it's CG less than 19" from the other end of the bridge. Which should be easy and should only require a driver to move as far as they can out to the end. I'm hoping and in theory this should be quick and easy. If there were still a weight issue there's a few pounds to play with but I think we're good as long as we balance with 115+ lb bots.
Can you share your math and some of the details?

I am assuming your robot is 123 pounds and all of the weight is at the end of the bridge - 44" from the center of the bridge. (is this correct?)

If so, then the center of a 145 pound robot needs to be at 37" from the center of the bridge, so only 7" from the edge.

I am taking 123 * 44 = 145 * x.
solve for x = 37.
