🤖 The Evolution and History of Pound for Pound Combat Robots

a sci - fi fi fi fi fi fi fi fi fi fi fi fi fi

Back in 1999 the first 1-lb antweight rumble was held in a hotel ballroom at Dragon Con—card-table arena, 2×4 rails, and a whole lotta zip-ties.
Fast-forward to today and pound for pound robots headline events like NHRL, Robot Battles, and MomoCon, live-streamed to 200 k+ fans on YouTube.

Why the obsession?

  • Low cost of entry—you can build a competitive 1-lb bot for less than a game console.
  • Garage-friendly—machine your titanium chassis with a desktop water-jet while the kids do homework.
  • Community—Discord servers buzz 24/7 with motor curves, ESC hacks, and “will-it-blend” weapon tests.

Milestone moment: Algos, the all-titanium spinner, proved that pound for pound doesn’t mean pound for puny—it went undefeated at Atlanta Mini Maker Faire with a 90 mph disk and a 325 mAh battery smaller than a fun-size candy bar.

🔧 Designing Your Pound for Pound Robot: From Concept to Combat

Video: Craziest ever robot fight: James v Depth Charge at NHRL.

We start every design session with three questions:

  1. What’s the meta in my arena? (wedges, drums, or vert-spinners du jour)
  2. What can I NOT afford to machine? (water-jet vs. hand-filed nightmare)
  3. Where will I shed 0.5 g when the scale says “453.6 g—OVER!” at 2 a.m.?

Design flow we swear by:

  • Sketch → CAD → FEA → Cry → Redesign → Victory
  • Weight budget = 50 % drive, 20 % weapon, 15 % battery, 10 % frame, 5 % “oops” margin.

Pro-tip: titanium is 45 % lighter than steel but $$$; 6061-T6 aluminum is the people’s champion for beginners.
