How about ...

In a 1v1v1v1v1 match;

A scoring benefit obtained by teaming up with another 'bot for moving each game piece to goal. Maybe passing from 'bot to 'bot over an obstacle or to another level. And if you were prohibited from using the same team more than X times in a match, a good chance of a single team winning each match.

For autonomous at the end;

A target that is not revealed until the end, maybe by an overhead or elevated green light or flag to be seen by the camera. That would prevent early posturing before the autonomous period.
