China’s “crayfish” agent craze could be the missing brain for home robots as US firms struggle to hook users

360 founder: robots need a “crayfish” brain

At a March 12 security and community event, Zhou Hongyi (周鸿祎), founder of 360 Group (360集团), argued that Chinese home robots still face barriers to household adoption because they lack the right kind of intelligence. Zhou said Yushu robots (宇树机器人) “now do motion skills well but lack a crayfish-like intelligent agent to act as a brain,” using the viral “crayfish” metaphor to describe small, scene-focused AI agents. He gave everyday examples — frying an egg, caring for an elderly person, tidying a room — where a robot must decompose complex tasks and learn to use tools, and suggested that household appliance makers should add robot-friendly interfaces to accelerate integration.

Yushu’s roadmap: factories, care stations and living rooms

That line tracks with public statements from Yushu Robotics (宇树科技/宇树机器人). Its founder and CEO Wang Xingxing (王兴兴) has outlined a decade-long vision in which robots work side-by-side with humans on factory lines, provide doorstep nursing and monitoring at community care stations, and become “all-purpose helpers” in living rooms — handling cleaning, supervision and tutoring. Wang has also emphasized that the sector cannot advance as a siloed effort and "needs close cooperation with open-source communities" to share results and cut industry-wide innovation costs.

Geopolitics, users and the competitive edge

This technical and ecosystem focus matters beyond China. It has been reported that US tech giants launching AI agents have struggled to convert early interest into broad, habitual use. Meanwhile, China’s grassroots “crayfish” agent phenomenon — cheap, focused agents tied into local services and hardware — could become a practical advantage when paired with an emerging domestic robotics supply chain. Add sanctions and export controls on advanced chips to the mix, and the incentive for Chinese firms is clear: stack software creativity and appliance integration to make up for chip access limits. Can lightweight, scene-specific agents plus closer ties between robot makers and appliance OEMs deliver mass-market robots before rivals catch up? The answer will help shape the next phase of the US–China contest over AI agents.
