After taking a closer look, it appears that the robot was about 1/8-1/4 to short to get the clearance needed to start over the obstacle. We are considering adding a wedge to the front of our robot to help lift us over barriers, or cutting a wedge from the underside of the kit frame, as seen in some testing videos here.
We saw success with a 4" tall, 4"deep (45* angle) wedge in a video, but aren't sure that we want/can go with something that size. Have any of you prototyped this, and what were your results?
For the record we are using 8" andymark rubber wheels. We are considering switching out the front pair for pneumatics tires as well. Our robot is back heavy, it that matters.

A lot of teams have done wedges to get themselves over bumps before. If you don't know, the 2012 game had some large see-saw-esque things, and some big bumps (similar to the rock wall) that robots had to cross. The wedge front was a very popular solution. Just remember, and I wish I could tell every rookie team this cause I see it all the time, you have to remember that you need bumpers to fit on the robot! Ensure that the wedge-front doesn't make it impossible to mount bumpers, and that, with bumpers on, the wedge isn't concealed. Best of luck!
