I’m going to need a couple of GPIO pins for a project I’m working on. Are any of the GPIO pins from the Raspberry Pi exposed on the robot anywhere?

Yes P704 and P705 have GPIO pins on them (as well as ground and 3.3V power) for applications that you may be interested in. Also its important to realize that P702 routes out all the Raspberry Pi pins. These route through the sonar board (and the sonar board uses many of them) but you can use them from the connectors on the other side of the board.

For more on the pins see:
