I read the rules as you would be allowed to have an additional battery on the robot to power the Pi alone.
According the R31
"Additionally, batteries integral to and part of a COTS computing device or self-contained camera are also permitted (e.g. laptop batteries, GoPro style camera, etc.), provided they’re only used to power the COTS computing device and any peripheral COTS USB input devices connected to the COTS computing device and they are securely fastened to the ROBOT."

This only applies when the battery is "integral to and part of a COTS computing device". Most (perhaps all?) COTS raspberry pis accept a power plug, and do not have an integrated battery. If you could somehow make the case that a USB power pack was a computing device (or camera), you could use it to power the pi over USB.
