Get drafted for Season 2
We're drafting both pilots and ghosts for Season 2 — a $100K prize pool across the season and four teams competing permanently. Pilots drive full-scale humanoids in the arena; ghosts build the Physical AI stack behind them. Pick your track and get in the pool.
Season 1 is live now, with $25K in prizes going out to current teams.

Drafted to compete permanently in Season 2
League robot assigned to selected teams — no purchase required
Drive the body. Build the mind.
Pilots control the robots in the arena. Ghosts decide who wins. Two official roles power every team — pick the one that fits how you want to compete.
Pilots
Drive the bodyWe're sourcing: Martial artists, dancers, and high-performance athletes, plus esports players, gamers, and content creators.
- The real-time nervous system of our humanoids
- Pilot full-scale humanoids via Direct Body Control — taught in-season, no robotics background needed
- Become the team's face and storyteller
- Grow through the ranks and build a legacy
Ghosts
Build the mindWe're sourcing: Roboticists, students, startups, and builders working across the Physical AI stack — hardware, software, and AI.
- Train movement and evolve autonomy
- Improve balance, recovery, and agility
- Analyze match data and evolve strategy
- Build the physical ai stack
Ultimate bots was built to create a real testing ground for humanoid robotics — a place to validate safety practices, pressure-test new research in public, and push real-world adoption forward. Our direct body control technology lets anyone become a robot pilot through natural movement.
Season 2 is the league's open call for the people who make the robots move — pilots in the arena and ghosts behind the stack. Top applicants get access to advanced hardware, compute, mentor support, and deep technical collaboration so they can experiment faster and build breakthrough behaviors.
The competition disciplines
UFB Fighting
The anchor discipline. 1-on-1 humanoid combat in a sanctioned cage, with strict weight matching and a champion crowned in every weight class.
UDB Dancing
Solo choreographed routines performed fully autonomously, judged on artistic expression, technical complexity, and vibes.
USB Soccer
Multi-agent humanoid team play, run fully autonomously — goals decide the match, with shots and possession as tiebreakers.
How the ghost track works
Open call
Ghost Trials runs as a continuous open call — apply directly through UFB Studio or at partner hackathons like CalHacks.
Qualifier sim & build work
Ghosts are selected on technical capability shown in qualifier work — policies and builds developed and validated in UFB Studio simulation.
Robot assignment
Selected teams receive a league-owned humanoid — currently the Unitree G1 — for the season. No purchase required; it's the student, indie, and startup path.
Matching & team formation
The league pairs pilots with ghosts and fills out each five-person team — manager, pit mechanic, and a supplementary member.
Season integration
Final teams compete across league disciplines for per-event championships and the season-long Ultimate Bots CyberCrown.
Apply to compete
One form for both tracks. Pick pilot or ghost, tell us how to reach you, why you want to join, and what makes you qualified. You apply as an individual — we pair pilots with ghosts and build out each team, so you don't need a full squad to enter. Our team reviews every application and follows up with next steps.
