Hello!
First post, please be gentle

I've been thinking about designing a robot.

I have a few basic/stupid questions that would affect the design.
I've not been able to find answers to, I'm sure any experienced roboteer would probably know right away:
  1. Are arena floors always made of steel?
  2. Is there always a trapdoor/pit in the arena?
  3. What is an event "whiteboard"?
  4. In featherweight events is there such a thing as a "judges decision" at timeout, or is it always a fight-to-death sort of thing?
  5. Do arena sides always have a border type thing, or do the walls sometimes all come flush to the arena floor. I.e. is there always a way for a robot to be thrown out of the arena?


That's all... for now at least

Cheers in advance!
