Actual original poster here.
It is NOT the power source. It is a high voltage capacitor which is used to activate the kicker mechanism. The robots are supposed to play robot football, and to shoot the ball they have a high energy coil to kick the ball.
The three circuit boards you see here are in order from top to down:
- Main processor board containing FPGA, processor, IMU and communications
- Motorcontroller bridges
- Kicker high voltage board

pic related, some of the horrible soldering work one of the soldering volunteers did on the motorcontroller board.
