Go to Post This isn't an engineering fair and demonstration, it's FRC. Defense is part of the game. You can't expect a good FRC team to just sit there and get clobbered by a full-court shooter; they're going to engineer a solution to the problem. - Kevin Sevcik [more]

Re: How much Bridge Space does your robot need?

You have to sum the moments in both directions considering the 3.5" hinge offset from center on either side (2 fulcrums). You also have to take the weight of the bridge and combined weight of the bots into consideration being applied in-between the 2 fulcrums. You can play with the attached spreadsheet if it makes sense to you. This might be helpful for anyone. You can vary the CG location and weights of 2 or 3 bots on the bridge.

The first case is for placing the CG of a 3rd bot left of center and the bottom case is for a 3rd bot right of center. So usually you would have the top case due to bot sizes.
