I would have to dissagree there andrew.

first of all, i would definatly (and im sure everyone else does)prefer my machine to get damaged to an out of control machine than me trying to remove the link from an out of control machine.

As to it being extremly expencive if the arena got damaged during the battrey dieing session. So What? as long as it contains the machine so its not a risk to people then im happy. i would much prefer to have a bill for £500 to repair the arena than a lawsuit against me from the person sueing me for injuery.

Dont forget, you can go home and fix your robot or arena no matter how damaged they get. you cant bring someone back to life.

I think its completely down to the event organiser. and being an event organiser myself i know its scary to say lol. but at the end of the day its the Event organiser that says if a specific robot is safe in a specific arena. If they asses all the possible risks and still belive they can contain it in a worst case senario (eg. robot going mad situation) then they are to blame if the robot escapes,hurts somebody during a battle etc...
