Watch Robots Battle! Grand River Rumble Tournament in Walker

Robots. Spinners. Flippers. Carnage.

The Grand River Rumble, West Michigan’s newest combat robotics league, is hosting a full tournament at Grand River Makerspace, and you’re invited to watch!
Builders of all ages have designed, 3D-printed, and wired up their own 1-lb fighting robots. Now they’ll face off head-to-head in an enclosed, polycarbonate-walled arena until one bot is left standing. Expect flying parts, flipped robots, plenty of cheering, and maybe a rock-paper-scissors tiebreaker or two.

What to expect
• Head-to-head tournament matches, 2 minutes each or until knockout
• Robots built by local kids, families, engineers, and hobbyists
• A chance to meet the builders, see their bots up close, and learn how to get into the sport
• A look around Grand River Makerspace, our community workshop with 3D printers, lasers, CNC, and more

Good to know
• Free to watch. No ticket needed, but registering here helps us plan for seating.
• All ages welcome. Minors must be accompanied by a parent or guardian.
• Fighting happens inside an enclosed arena, so spectators stay safely outside the action.
• Arrive early to grab a good spot!
