It's too thick to be a standard belly pan. I'm too lazy to search atm, but I'm fairly certain I remember several WCD teams stating they use 1/8" plate as a belly pan.

There are 2 vertical black cylinders underneath it, if you look through the gussets. Additionally, the far edges of this have holes that look like they may match up with the long rack gears Adam posted a few weeks ago. Finally, the large right-angle hole on the left hand side doesn't match any common gearbox patterns for a drive train.

Are you even hanging tubes with this bot?
