Generations, not upgrades.
Rivets develop through simulated generations. Their frames, joints, actuators, and ways of moving can change as designs are varied and selected.

take its course.
Evolving mechanical athletes.
A sporting universe taking shape.

01 / The league
What happens when we let digital athletes evolve and compete?
Rivet League is a futuristic mechanical sports project we're building around that simple idea.
Meet the Rivets: mechanical creatures whose skeletal structures, movement, and strategies develop over generations through physics-based simulation. Some will thrive. Others will fail spectacularly. And sometimes, evolution might surprise us all.
The simulator is still in active development. We're building toward a league of individual athletes, bloodlines, rivalries, and championships.
02 / The first planned championship
Every winning design starts somewhere.
Our first planned championship puts evolved mechanical athletes on the race track. The question is simple: which designs can turn generations of change into a winning run?
As competition develops, you'll be able to follow successful designs and their bloodlines, unexpected breakthroughs, emerging rivalries, and the dynasties they might become.
No championship has been held yet. Public competitions and official athlete introductions are still ahead.
03 / How it works
The project is built around a simple rule: performance comes from the simulation. The following principles guide the league we're developing.
Rivets develop through simulated generations. Their frames, joints, actuators, and ways of moving can change as designs are varied and selected.
A promising design still has to move. Evolutionary computation explores possibilities; simulated physics determines how those bodies perform.
Competition outcomes will come from the simulation. Success, failure, and the occasional spectacular flop emerge from what the Rivets can actually do.
04 / Follow the league

The athletes' stories are still ahead of us.
