10月27日，小米技术披露仿生灵巧手技术探索成果：以小米汽车工厂柔性制造场景为设计原点，带来高自由度仿生灵巧手的最新技术思考。
What happened
Xiaomi disclosed a new 21-degree-of-freedom biomimetic robotic hand informed by data collection and analysis covering 1827 automotive factory standard operating procedures. Xiaomi reports that simulation ablations showed 17–21 degrees of freedom improved average stable grasping success by 15%–38% over 6–15, with gains slowing at 23 or more. The hand uses hybrid actuation and tendon tension control, alongside improvements to heat dissipation and full-palm tactile sensing.

Xiaomi revealed a 21-degree-of-freedom biomimetic robotic hand whose design draws on data collection and analysis covering 1,827 standard operating procedures in automotive factories. The hand combines hybrid actuation and tendon tension control with improvements to heat dissipation and full-palm tactile sensing. Xiaomi said simulation ablation tests showed that configurations with 17–21 degrees of freedom improved average stable grasping success by 15%–38% compared with configurations with 6–15 degrees of freedom, while gains slowed at 23 or more. Those simulation results informed its choice of 21 degrees of freedom for a hand designed around flexible manufacturing tasks in Xiaomi’s automotive factory.
