That's what's holding the two sides of the robot together. They aren't using any gussets or other brackets that attach to both the cross-tubing and the wheel tubes*. If they used nut & bolt at each end, the cross tubing would slide right off of the milled piece linked from post #3.
Edit:
* except the belly pan.
