Xiaomi unveils 21-DoF full-palm tactile bionic hand: 324-gram palm, 1,500 tactile points

Xiaomi has unveiled a bionic hand with 21 degrees of freedom and 1,500 tactile points across the full palm. The palm weighs 324 grams and is driven by 26 motors, with tendon-driven actuation as the main approach plus 5 direct-drive degrees of freedom. The team selected 1,827 of the 2,579 standard work procedures across 16 work sections at the pilot center of Xiaomi Auto's intelligent manufacturing department, collected multi-angle video and motion-capture data to work backward to the joint configuration, and says that in simulation the average stable-grasp success rate in the 17-to-21 degree-of-freedom range was 15% to 38% higher than in the 6-to-15 range, with gains slowing markedly after 21.
