Round Robots...?

Okay, so a couple of us were thinking about the new bumper rules (and I have to say, I love them), when someone pointed out the idea of a completely circular robot. Would a robot designed to be a circle need bumpers, as there are technically no corners?

The bumpers do need to be round and we had to curve the wood and it wasn’t that good of a year.
