There seems to be a battery box on the photo right side (near the SRXs), so the RIO presumably fits where you can see a fair bit of belly pan and disconnected wires (near the radio).

I see rhino tread, so presumably a sapper robot as a primary function.

The rollers seem to be designed for a simple intake/return to score low goals. I don't see how they reach outside the frame perimeter, so this may require some precision driving for boulder pickup - especially tricky as I don't see any sign of a camera at that end. I'm guessing the chassis is 26-28" wide to admit a boulder through the gap in the bumpers (here implemented in clear plastic). With the additional width of real bumpers, that may present a problem getting onto the batter.
For debugging we had the camera plugged into the pi, but the camera was unplugged when they mounted it. Since our catapult isn't done, it wasn't plugged in again because it's main purpose (auto-targeting towards the high goal) serves no purpose. I don't know much about the bumpers - I'm just a programmer. The roboRIO is under one of the plexiglass shelves. We just drive up to a boulder and it grabs it - there's a camera on the back too.
