Weapons
Lifting weapons
These weapons lift the opponent and cause them to lose control of motion.
Some lifters are used to gain control over their opponent so they can be thrown in a pit or tipped upside down, while other lifting designs are simply used to give the robot more control over their opponent.
Wedges
A wedge is a sloped front that might lift an opponent off the ground, even slightly. Many bots have wedges in their design, even if it appears to be only incidental to the bot's operation.
Uses
- Breaking contact between the opponent's wheels and the ground
- Lifting an opponent until their weapon is unable to reach you, or no longer effective
- Lifting an opponent to keep it from attacking your active weapon, assuming your weapon has greater reach than theirs
- Lifting an opponent to feed it into your active weapon
- Armored defense; deflection against attacking weapons
- Crushing opponents against walls
- Pushing opponents into hazards
- Lifting opponents out of bounds or into a pit
Generally the bot with the lower wedge is at an advantage, but imperfections in arena floors and walls can make it very difficult to drive with a ground-scraping wedge.
Types
- Fixed wedges are attached to the body of the bot, or are part of the body. Many insect-weight bots have only two wheels, and a wedge or scoop holds up the front of back of the bot. A fixed wedge slightly above the arena floor can be effective, but may be ineffective against a lower wedge. Wedges that rest on the floor can become jammed due to floor scratches, uneven floors, and damage to the bot, and can be stuck under walls or barriers.
- Hinged or ground-scraping wedges slide on the floor and may be more likely to get under an opponent, and they pivot to discourage jamming on uneven floors.
Wedgelets
Small wedges that are used to get under opponents are often called wedgelets. These small wedges can often save weight but can be difficult to make strong enough to survive an opponents weapon. The 'Wolverine Claws' by BotKits.com are a very effective example of a wedgelet. Wedgelets offer little in the way of armored defense except against low attacks, but they have the benefit of being individually replaced without the cost of renewing a full-sized wedge.

Angled spinner
Full body weapons
Large portions of your bot, or even the entire bot, can be put into motion as a spinning weapon. These are tricky to build It is crucial that the bot be perfectly balanced, with its weight evenly distributed, so that it doesn't lose control or tear itself apart.
Shell spinner
Ring spinner
This type of bot has a round, steerable core surrounded by a spinning ring.
Meltybrain
The entire bot spins rapidly, but using computer-assisted controls, it can still be steered. See Melty Brain.
Thwackbot
Any of the above bots, but incorporating a hammer, or an arm with spikes, extending from the side of the bot. It is driven into position and then commanded to spin in place to create a circular zone in which other bots may be damaged.
Full body flail
A variant of the thwackbot that incorporates one or more flails (like a mace, or a chain) which can be whipped around to cause damage. These are more difficult to operate, since the weight distribution of the weapon is not fixed.
Full body drum
Hammer weapons
Hammers inflict destructive shock waves, dents, and puncture damage on opponents.
