💥 The Explosive History of Projectiles in Robot Combat: From Backyard Brawls to BattleBots Arena

Robot combat started as a DIY hobby in garages and basements, where anything went. Early bots sometimes experimented with projectile weapons—think homemade cannons or harpoons. But as the sport professionalized, safety and fairness became paramount.

  • Neptune (Season 3.0) was the first BattleBot to use projectile weaponry: six single-use harpoons. It was a bold experiment but lost its only fight and never returned.
  • The reboot era saw Double Jeopardy, the first cannon-equipped robot, debuting in 2018. It fired metal slugs using a pneumatic system powered by nitrogen (CO2 banned for safety). Despite some malfunctions, it remains the only cannon bot to compete seriously.
  • Other designs like Broadside proposed multi-slug cannons but never made it to the arena.

Our engineers recall the excitement when Double Jeopardy fired its first slug live on TV — a moment that made us realize projectile weapons could be thrilling but also risky. The history shows a cautious embrace of projectiles, with strict limits.

For a deep dive, see the BattleBots Cannons Wiki.

📜 Understanding BattleBots Rules: The Projectile Predicament Explained

BattleBots rules are designed to keep fights exciting and safe. The projectile ban is a cornerstone of this balance. Here’s why:

  • Safety: Projectiles can fly unpredictably, risking damage to the arena, cameras, crew, and even spectators.
  • Fairness: Projectiles can be difficult to defend against, potentially ending fights too quickly or unfairly.
  • Technical complexity: Pneumatic and explosive systems add weight and complexity, often compromising robot durability.

The official rules (see Robot Combat Rules and Regulations) state:

“Weapons that shoot a projectile or gas must have physical means to prevent firing AND block the expulsion of a projectile.”

This means no firing metal slugs, balls, or other objects freely. Pneumatic systems must use nitrogen or compressed air, not CO2 (banned since 2015).

Our team’s experience building pneumatic systems taught us that controlling pressure and safety valves is critical—one wrong move and you risk catastrophic failure or disqualification.

🔍 What Exactly Counts as a Projectile in BattleBots? Defining the Forbidden

The term “projectile” covers a wide range of launched objects. Here’s what BattleBots considers projectiles:

  • Untethered solid objects: Metal slugs, ball bearings, harpoons, or any solid object shot freely.
  • Tethered projectiles: Objects attached by cables or tethers (historically banned but sometimes allowed under strict rules).
  • Liquids or gases expelled as weapons: Water, oil, lubricants, or chemical sprays.
  • Entanglement devices launched or deployed: Nets, ropes, or sticky substances.

Key point: The robot must not expel any object or substance that leaves its body and travels through the arena to damage or impede the opponent.

Our engineers have seen some creative borderline cases, like sticky pads or “sticky foam” — all rejected because they violate the projectile or fouling weapon rules.

🚫 The “Forbidden Weapons” List: Beyond Just Projectiles – What Else Is Banned?

Projectiles are just one part of a broader forbidden weapons list designed to keep robot combat fair and safe. Here’s a quick rundown:

Forbidden Weapon Type Examples Reason for Ban
Electrical weapons Tasers, stun guns, EMP devices Safety, interference with controls
Fouling weapons Sand, ball bearings, glue Damage to arena, unfair advantage
Liquids and lubricants Water, oil, adhesives Messy, unsafe, fouling
Visual obstruction devices Smoke, lasers, strobe lights Safety, visibility impairment
Mutually destructive Self-destruct, battery bombs Safety, sportsmanship
CO2 pneumatic systems CO2 gas for weapons Safety, storage hazards

For a full list, check out the Forbidden Weapons Wiki.

Our fans often debate the fairness of some bans, especially on nets and adhesives, which can be clever but are ultimately too risky for the arena.

🛡️ Why the Ban? Safety, Fairness, and Spectacle in Robot Fighting

Why does BattleBots say no to projectiles? Here’s the scoop from our engineers and fans:

  • Safety first! Flying metal or liquids can damage cameras, injure crew, or cause arena hazards.
  • Fair play: Projectiles can end fights instantly, reducing the strategic depth and excitement.
  • Spectacle: Fans love seeing robots smash, flip, and shred each other up close — projectiles can feel like “cheap shots.”
  • Technical constraints: Pneumatic cannons add weight and complexity, often forcing compromises in armor or mobility.

One of our engineers recalls a test firing of a pneumatic slug that went wildly off-target — a terrifying moment that cemented our respect for the rules.

🤔 Are There Any Exceptions? The Nuances of “Non-Damaging” Projectiles and Controlled Releases

While the general rule is a hard no, there are some nuanced exceptions:

  • Flamethrowers and heat-based weapons are allowed under strict fuel limits and safety protocols.
  • Tethered projectiles have been allowed experimentally (e.g., harpoons), but only under strict control and limited usage.
  • Non-damaging projectiles like lightweight foam or fabric launched for distraction are generally banned due to fouling risks.
  • Compressed gas bursts (not expelling solids) may be allowed if they don’t propel objects.

Our team has experimented with pneumatic “pushers” that don’t shoot projectiles but use air blasts to disrupt opponents — a clever workaround within the rules.

Types of “Projectile-Like” Mechanisms & Substances: A Deep Dive into the Rules

1. 💨 Pneumatic Launchers and Air Cannons: The “Projectile” Poster Child

Pneumatic cannons are the classic projectile weapon, shooting metal slugs or harpoons with compressed nitrogen.

  • Allowed? Generally no, except for Double Jeopardy, which was allowed as an experimental exception.
  • Why banned? Safety risks, unpredictable trajectories, and arena damage.
  • Design challenges: Pneumatic tanks add weight; CO2 banned since 2015 for safety.
