If the drive team is carrying this device it must be completely unpowered.

<T25> The only equipment that may be brought on to the ARENA is the OPERATOR CONSOLE,
non-powered ANALYST-to-FEEDER signaling devices, reasonable decorative items, and
special clothing and/or equipment required due to a disability. Other items, particularly those
intended to provide a competitive advantage for the TEAM, are prohibited.

If it's going on the robot it of course has to hooked up to the control system etc.

Very cool idea,
