Xiaomi Unveils 21-Degree-of-Freedom Biomimetic Dexterous Hand
4 reports · 4 sources
The Xiaomi Robotics team has unveiled a 21-degree-of-freedom biomimetic dexterous hand, stating that it has completed closed-loop validation from scenario requirements to engineering design. The hand uses the Xiaomi Auto Intelligent Manufacturing Department's pilot test center as its data source; the team selected 1,827 steps from 16 work sections and 2,579 standard operating procedures (SOPs), collected video and motion-capture data, and worked backward from this to derive the joint configuration. In terms of specifications, the hand uses a hybrid drive with 26 motors, primarily tendon-driven with 5 direct-drive degrees of freedom added, and 1,500 tactile points across the entire palm; the tendon-drive motors are concentrated in the forearm, and the hand weighs 324 grams. Xiaomi says that simulation ablation analysis based on real work data shows that the average stable-grasp success rate in the 17–21 degree-of-freedom range is 15%–38% higher than in the 6–15 degree-of-freedom range, and that the improvement slows markedly when degrees of freedom rise to 23 and above; in real-machine tests, for multi-posture grasping of factory parts and tools, both anthropomorphism and success rate improved compared with the previous lower-degree-of-freedom version. The above grasping results are all Xiaomi's claims. The hand's single-hand power consumption can exceed 100 watts, and heat dissipation capability affects continuous high-load operating time; its durability still needs sustained validation on real production lines.

- 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.

- Xiaomi announces 21-DOF bionic hand, completing closed-loop validation based on 1,827 factory SOP data points
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.

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.
