Safe arenas can be made. but its not just haveing meter thick polycarbonate. its the quality of the arena construction thats important. It takes along time and expirence to iron out all the weak points just like our robots. weve upgraded our arena over a period of around 3 years....... now its perfect lol nothing is perfect but you can get close. I dont think the potential of what robots can do has been realized still :sad: even with featherweights.

Completely agree with James B.
