Re: Is FRC giving high CG robots a free pass on defense?

Re: Battlebots with FRC mentors and FRC suppliers

Yeah for example, Donald Hudson is one of the nicest guys you'll ever meet (and both an FRC mentor and longtime battlebot builder) but for TV they somehow painted him as the bad guy! It was good for...
