National Havoc Robot League

National Havoc Robot League (NHRL) is the largest and most accessible robot combat league in the world, home of the 3lb, 12lb and 30lb world championships. We host a series of tournaments throughout each year at the House of Havoc, our HQ in Norwalk, CT, culminating in the World Championships. Builders combine groundbreaking technology and off-the-wall ideas to amaze audiences, compete for thousands of dollars in cash prizes, and attempt to claim the coveted Golden Dumpster. Each tournament boasts more than 100 robots and hundreds of builders and fans from all over the world.
