Shenzhen-based EngineAI launched the world’s first commercialized humanoid robot combat league. URKL (Ultimate Robot Knock-out Legend) opened global registration on April 3. Deadline: April 30. The champion walks away with a solid gold belt — 10 kg, valued at roughly $1.45M. Top 16 teams each receive a T800 robot for continued R&D.
The Hardware
The T800 is a full-size humanoid: 173 cm tall, 75 kg, 29 degrees of freedom, peak joint torque of 450 N·m. An NVIDIA AGX Orin delivers 275 TOPS of AI compute. Solid-state battery runs 4-5 hours. Movement speed hits 3 m/s. 360-degree LiDAR plus stereo vision handle perception. Pricing starts at $40,500 for the Basic edition and goes up to $80,800 for the Max (46 DOF with dexterous hands).
Developer Access and the URKL Format
URKL runs on “standardized hardware + differentiated algorithms” — every team gets the same T800, the fight is purely in code. Motion control, balance algorithms, perception, autonomous decision-making. Best-of-three rounds, five minutes net time per match. No violent hardware mods allowed.
The Open Source, Pro, and Max editions ship with SDK/API documentation for secondary development. The Orin module handles on-board inference; teams deploy custom control stacks over WiFi, USB, or LAN. Grand final runs December 2026 through January 2027.
