Yes I realise that, but these rules wern't in affect then, which is why I was making the pointCavecrusher wrote:Than DBA shouldn't be allowed either, same perimeter protection, same amount of Ti. BUT it has been allowed to compete, and succesfully i might add

Edit: Maybe the rule would be better reworded in a way such as this;
'A continuous peice of metal armour must not encompass the robot's perimiter to an extent that the robot could be seen as 'invulnerable' to attacks from aggresive weaponry from all sides. If you are unsure whether or not your design will be allowed, please contact a commitee member or the event organiser, or you may risk disqualification.'
This seems to make a lot more sense to me.
