I would simply like to refer you to this from my previous thread-

Everyone seems to have an opinion on how to build a winning robot for Robot Wars I found,

most turned out to be dreamers with concepts built around a radio controlled car and numerous ideas

for weapons- most of which would be illegal even under the oldest rules like machine guns and

electrical dissruption ect.

I' m working on a unique weapon myself so I'm all for new ideas-sensible ones
