One of Tesla CEO Elon Musk¡¯s worries was on full display at technology show CES in Las Vegas this week. Chinese-made human-like robots were everywhere across the exhibition floor, playing table tennis, sweeping floors and practicing kung fu.

China¡¯s latest robotics innovations were delivered to the heart of America¡¯s technology showcase, serving a constant reminder of the technological race between the world¡¯s two biggest economies. While Santa Clara, California-based Nvidia and Advanced Micro Devices hosted keynotes touting ever faster artificial intelligence chips, a legion of budding Chinese robot creators occupied much humbler booths with machines giving life to the notion of physical AI.

Fourier Intelligence unveiled its latest GR-3 humanoid; Booster Robotics deployed over 30 robots in synchronized choreography; X-Humanoid demonstrated the sprinting speed of its Tiangong Ultra, winner of last year¡¯s Beijing humanoid half-marathon; and Unitree showcased acrobatic routines performed by a dozen machines. Booths operated by Galbot, AgiBot and EngineAI showed off multitasking capabilities and industry-ready systems to prospective buyers, signaling ambitions to expand overseas and translate technical prowess into global sales.
