Elon Musk says robot fights are fun after watching China’s humanoid robot battle

A Shenzhen robotics company staged what it called the world’s first industrial-grade humanoid robot free-fighting demo.

Two EngineAI T800 robots faced off in an MMA-style cage, and one kept fighting even after losing its head-mounted sensors.

The video went viral after Elon Musk reposted it on X and said robot fights are fun.

The demo highlights rapid progress in humanoid balance, motion control, and combat-style movement.
