2025 NHRL Open World Championship - Qualifier Round 4

Hundreds of robots from around the world duking it out with highly dangerous weapons to win a Golden Dumpster trophy, thousands of dollars in cash prizes and book a place at NHRL’s World Championship finale.

Non-stop up-close action, food trucks, breweries, cocktails and surprises at each event. You can even drive and fight with a robot with our test-driving experience, or learn how to build your own with Havoc Academy.

Nothing prepares you for the feeling of being cage side when two big robots go head to head. All at our purpose built facility at 165 Water Street, Norwalk CT.

It’s the most fun you can (legally) have with a robot.
