China wants to solve the hardest problem in robotics – making hands
Summary
China is aggressively pursuing the development of highly dextrous robotic hands, considered the most challenging problem in robotics, to advance "embodied AI" and transform humanoid robots from novelties into practical tools. Companies like LinkerBot, founded in 2023, produce 5,000 hands monthly, aiming for a \$6 billion valuation and prosthetic hands at \$1,000. The Chinese dextrous hand industry reached 50 billion yuan (\$7.4 billion) in 2025, a significant increase from 13 billion yuan in 2024, driven by China's robust manufacturing supply chain, which facilitates component sourcing. While hardware development is progressing rapidly, the primary hurdle remains software: teaching hands complex manipulation tasks. This requires extensive data collection for 3D models, often through teleoperation or sensor-filled wearables like Wuji Technology's glove, to capture nuanced movement, pressure, and touch information, which is currently scarce.
Key takeaway
For AI Scientists and Robotics Engineers focused on developing practical humanoid robots, recognize that dextrous manipulation remains the primary bottleneck, far exceeding locomotion challenges. Your efforts should prioritize advanced software for hand control, specifically exploring innovative data collection methods like sensor-filled wearables to capture critical pressure and touch information. This approach is essential to move beyond basic movements and enable robots to perform complex, real-world tasks, transforming them into truly useful products.
Key insights
Developing dextrous robotic hands is the critical, most difficult hurdle for practical humanoid AI, with China leading the charge.
Principles
- Robotic hand dexterity is 100 times harder than humanoid locomotion.
