Go to Post Honestly, just when I thought FIRST had finally created an FRC game without any near universally-hated rules, they went ahead and made one in TM 1. - artdutra04 [more]

Re: FRC488 Driving Over the Bump

Interesting! Do you have a number for how high the CG is now?

When the robot is climbing the ramp, at a 45 degree angle, the height of the CG affects where the balance point is, relative to the 3rd wheel. Having a higher CG moves the center of mass behind that wheel, so the nose does not want to come down as it tries to crest the bump

Anyways, we're hoping that moving our CG foward (or back and driving over the bump backwards) as well as increasing traction on the center wheels will give us the extra umph we need to get over the bump.

Thanks again for posting this info!
