## Summary

Xiaomi has announced that its new-generation high-DOF bionic hand has completed closed-loop validation from scenario requirements to engineering design, with specifications of 21 DOF, 26-motor hybrid actuation, and 1,500-point full-palm tactile sensing. The development was based on motion-capture collection from 1,827 of 2,579 SOP steps across 16 work sections at the pilot center of Xiaomi Auto's intelligent manufacturing department. Simulation ablations show that the 17-to-21-DOF range improves average stable-grasp success rate by 15% to 38% over the 6-to-15 range.
