The Damage category is for how much damage the bot can deal with its opponent while remaining intact itself. A robot driving over the kill saws will lose points here unless it had good reason to do so, while a robot that can attack its opponent's weak areas will gain points. The Strategy category is about how well a robot exploits its opponent's weaknesses, protects its own, and handles the hazards. A robot who hangs back safely from its opponent will not get many Aggression points one in there fighting the whole time, however, will. The judging categories are Aggression, Strategy, and Damage. In about half the matches, both robots survive the three minutes at that point, three judges distribute a total of 45 points (15 points a judge, 5 points per judge per category) over three categories. This ends the match ten seconds later the opposing driver is "asked" (but not instructed) not to attack during the ten-second count. The driver may also call a "tap-out" to forfeit the match if his or her robot is about to be destroyed. If a robot is unable to move for thirty seconds, because it is too badly damaged or it is stuck on the arena hazards, it is declared knocked out. In that case, the people entering the BattleBox are equipped with a fire extinguisher. The other scenario is that one or both 'bots have caught on fire. One is the event that the robots are stuck together and cannot separate or that both have simultaneously become immobilized.


There are only two events that cause the match to be paused and people enter the BattleBox. During a match, two robots do their best to destroy each other using whatever means available. Since the rules change, walking robots have entered the competition, but none have achieved any success beyond preliminary rounds. For BattleBots 4.0 and beyond only a 20% weight bonus was given to walkers and the technical rules specified that walking mechanisms did not use cam operated walking mechanisms as they were functionally too similar to wheel operation. The rules changed following the victory of a heavyweight StompBot (Son of Whyachi) at BattleBots 3.0. 'Walking' robots ('StompBots') propelled by means other than wheels were initially given a 50% weight bonus.

Superheavyweight – 340 pounds (154 kilograms).Heavyweight – 220 pounds (100 kilograms).Middleweight – 120 pounds (54 kilograms).At the final tournaments the classes were: The weight limits increased slightly over time. Robots at BattleBots tournaments were separated into four weight classes.
