A Robattle (or Robottle in Japanese) is an activity in which a Medafighter competes against another using his/her Medabot in a battle. The winner is the Medafighter whose Medabot causes the opponent's to cease function first. It is usually monitored by a referee, usually in the anime by Mr. Referee, however, if no referee is present, the match will take in no rules, and will not count for point if there is a winner, also, no Medaparts are given to the winner from the loser. If the Medafighters engage in a Submission match, instead of a Standard match (where no referee is present), the winner of a Robattle gets to take a part of his/her choice from the Medabot of the loser for keeps.
