Has anyone got any ideas for a Robot Wars type TV program?

We have the Back street type format, bunker style.

How about Clan Wars, there are groups of robot teams with say 5 or 6 robots, come together to a big battle scene,
They could be grouped by geographic area, robot type or just friend groups.

The format could be anything from last man standing to flag capture or similar goal.
Terrain could be old industrial building with flat floors to anything outside.
