====== Drop Off Zone ======
A drop of zone is a feature unique to [[Antweight arena]]s.  It is essentially a trench around the sides of the arena, which because 50% of the arena side must be open with no wall, robots can be pushed out into.  If a robot is pushed out, it is declared the loser of the fight.

As of version 4.0 of the [[Antweight World Series Rules]], the drop of zone must comply with the following conditions:

  * The minimum distance between the edge of the unwalled part of the arena and the battle box (and therefore the width of the ditch) is 150mm.

This is so even the largest [[Antweights]] can fit into the ditch.
