Xiaomi unveils 21-DoF biomimetic dexterous hand, validated on 1,827 factory SOPs

Xiaomi has disclosed its exploration results for a biomimetic dexterous hand, designing a new 21-DoF biomimetic dexterous hand based on the collection and analysis of 1,827 standard operating procedures (SOPs) at Xiaomi's automobile factory. Simulation ablation analysis showed that in the 17–21 DoF range, the average stable grasp success rate improved by 15%–38% compared with 6–15 DoF, while the improvement slowed markedly at 23 DoF and above. The hand uses a hybrid actuation and tendon tension control scheme, with systematic optimization of the heat dissipation system and full-palm tactile sensing.
