The global humanoid robot industry is projected to undergo a massive shakeout between 2027 and 2028, leading to the elimination of 50% to 70% of tail-end companies. Surviving this purge requires mastering six core technological bottlenecks: unstructured environment adaptation, dexterous hand control, lightweight structures, extreme environment durability, ultra-low power consumption, and the integration of AI models with embodied intelligence. In the current competitive landscape, the United States leads in the "brain" (algorithms and chips), while China dominates the "body" with over 60% of global manufacturing output. As production costs decrease, the market will consolidate into an oligopoly of 5 to 6 global leaders, shifting their business models from hardware sales to SaaS-style subscriptions
