What Are Fighting Robots?
Fighting robots are remote-controlled machines built to compete head-to-head in an arena. Builders design, fabricate, and program robots from the ground up — choosing drive systems, weapon types, armor materials, and control electronics — then put them to the test against other builders' creations. Weight classes range from tiny 150-gram antweights that fit in your hand to massive 250-pound heavyweights that can flip a car.
It's engineering with consequences. Every design decision matters — a faster spinner hits harder but is less stable, heavier armor means less weight for weapons, a more complex drive train gives you better control but more points of failure. Builders learn by doing, iterating, breaking things, and rebuilding better.
STEAM Education at the Core
BotBrawl exists because we believe building robots is one of the most effective ways to learn science, technology, engineering, art, and math — not from a textbook, but by getting your hands dirty.
Our events welcome builders of all ages and experience levels. Whether you're a student building your first antweight out of a 3D printer, a hobbyist machining parts in your garage, or a seasoned competitor — there's a place for you at BotBrawl.
What We Do
BotBrawl is Canada's grassroots fighting robot organization. We run tournaments, support affiliate organizers across the country, maintain the national ranking system, and work to grow the Canadian combat robotics community.
We provide the infrastructure — standardized rules, safety protocols, a national ELO ranking system, and event management tools — so organizers can focus on running great events and builders can focus on building great robots.
Get Involved
Whether you want to build, compete, organize, or just watch robots smash into each other — we'd love to have you.
