I like the idea of rule 2 ...BUT

..The problem with all these rules is if a world champs was ever held.. You'd basically be discouraging competitors from across the world from entering unless they modified there machines...The whole point in the recent rule changes (weight increase) was to get the UK robots to be inline with other country's. I think making new rules now would totally un-do the work thats been done to get a global rule set.
