Thanks for posting this Madison. We tried ours out and had some difficulty getting over the bump. Having "stuff" such as the framework to hold the bumpers and ball kicker mounted up higher seems to make it more difficult, because the CG moves up and the robot wants to sit at a 45 degree angle when rearmost wheel gets to the ramp.

I suggest you give it a try with more weight on the robot, approximating the final CG position.
