King Buxton

King B Powerworks was a box shaped competitor with two lifting spikes at the front and a circular saw at the back. It was also invertible, allowing it to run even when it was flipped over. It competed from Series 2, where it was known as King Buxton, to Series 5 and also Series 7. In Series 4, the robot was renamed King B3 and thereafter it was renamed "Powerworks" after the motors, which were run at the highest voltage the rules would allow.
