During our first practice match at UTC, our robot failed to make it up the bridge. The wheels were losing traction, so we took our robot back to the pit and began making grooves.
We simply took a few utility knives and cut out small grooves spaced about 1/4 to 1/2 inches apart. We did this to both our drive wheels and took it back for testing.
Our robot has enough traction to make it over the bridge during our second practice match; however, we had to make a running start for the bridge. So, we took it back to the pit again and began notching the grooves closer together.
Now, we have plenty of traction to get over the bridge.
One thing I did notice on a lot of the robots at UTC that we didn't have time to put in: timing belts. A lot of the robots looked like they just wrapped timing belts around their wheels, creating tread-like wheels.
