Not sure if youre serious Jack, but if so theres quite a few problems with the design! Heavyweights have to weigh in at 100Kg for a start. Drills dont really work in practice against modern armour, but in any case all the rotating weapons youve specified would not be allowed to run in either the Roaming Robots or Robots Live arenas at the moment for safety reasons. Also Im afraid itd never turn with that arrangement of wheels and would proabably fall over at the slightest touch too! Interesting looking concept though and dont be put off if you are keen to build. Usually one good (and legal) weapon is a better bet than several weaker ones.
