===Weight classes===
Robots at BattleBots tournaments were separated into four weight classes in seasons 1–5. The weight limits increased slightly over time. At the final tournaments, the classes were:

*Lightweight – 60 pounds (30 kilograms)
*Middleweight – 120 pounds (54 kilograms)
*Heavyweight – 220 pounds (100 kilograms)
*Superheavyweight – 340 pounds (154 kilograms)

Starting in season 6, there were no longer separate weight classes, while the weight limit for heavyweights was increased from 220 to 250 pounds.

"Walking" robots (stompbots) propelled by means other than wheels were initially given a 50% weight bonus. The rules changed following the victory of a heavyweight stompbot (Son of Whyachi) at BattleBots 3.0. For BattleBots 4.0 and beyond only a 20% weight bonus was given to walkers and the technical rules specified that walking mechanisms do not use [[Cam (mechanism)|cam]] operated walking mechanisms as they were functionally too similar to wheel operation. Since the rules change, walking robots have entered the competition, but none has achieved any success beyond preliminary rounds. As of 2020, true walkers are given a 100% weight bonus, allowing the only competing walker, Chomp, to weigh 500 pounds.<ref name=":0">{{Cite web |title=BattleBots rules & entry – BattleBots |url=https://battlebots.com/rules/ |access-date=2022-03-03 |language=en-US}}</ref>
