Now, teams like 188 and 217 in Rochester had pinching rollers, which weren't spring loaded, but they managed to keep the ball on the ground with no difficulties. This just goes to show that there are multiple ways to solve this problem.

One question about your duel rollers. Are they both motorized or is one just there to stop the ball from jumping the robot and going too deep into the bot?
