Yangtze River Delta 长三角
The most concentrated robotics cluster in China — industrial arms, cobots, AGV, vision, servo.
The Yangtze River Delta is China’s densest and most complete robotics ecosystem. Around Shanghai, Suzhou, Hangzhou, Wuxi and Nanjing it combines upstream components (Leaderdrive harmonic reducers, Hesai lidar, Estun servo-and-control), a deep bench of industrial and collaborative OEMs, and a remarkable cluster of humanoid and embodied-AI startups — Unitree, AgiBot, Fourier — alongside service-robot leaders like Keenon.
What sets the delta apart is integration: a robot can be specified, sourced, prototyped and manufactured almost entirely within a few hours’ drive, supported by capital, universities and local-government industrial parks. That density is the region’s real moat.
