Yap, i forgot about a shallow dome, no corners at all!

Breaker Box isn't a wedge/plow, that thing is a lifter and it as lots of power. In one video, to celebrate the victoty, Jim goes full power with the lifter and the robot balances on the plow and the body spins like crazy.
In my opinion, he only lost against SwerSnake because he didn't have time to fully charge the battery, as you can see at the end of the fight, he was dominating the snake.
