Good point Mark regarding the wheel guards on Concussion . But I would put bet that most bouts go in favour of the modified robot than the non modified.
Interchangeable weapons to are fine with me as long as they are registered on competition entry and comply with the weight limit. I think the key word is modify. Replacing any broken part with another materials is fine as long as the robot design remains the same as on entry. I suppose modifying the design during the competition is what bugs me. Seems unfair.
