The all-new Xiaomi CyberOne breaks cover, featuring a full-palm tactile bionic hand. ๐คโจ
Xiaomi Technology's official WeChat account just dropped a massive update, detailing their research into full-palm tactile bionic hands and revealing a total redesign for the CyberOne humanoid.
They have slashed the hand's volume by 60% to achieve a perfect 1:1 human scale, matching the dimensions of a 1.73-meter male hand to simplify sim-to-real data mapping.
The new configuration boosts active degrees of freedom by 83%, pushing the dexterity closer to the human standard of 22-27 DOFs for complex manipulation.
To tackle the 30W of heat loss from high-density 100W motors, Xiaomi integrated 3D-printed metal liquid cooling channels that function as bionic sweat glands.
This system evaporates 0.5mL of water per minute, providing 10W of active cooling to prevent thermal throttling during high-load industrial shifts.
Tactile sensing covers a massive 8200 sq mm, providing full-palm feedback that allows the robot to "feel" its way through tasks when vision is obstructed.
Reliability is a standout, with the hardware enduring over 150,000 grasping cycles, far surpassing the 10,000-cycle failure threshold common in many tendon-driven designs.
In automotive assembly tests, CyberOne already maintains a 90.2% success rate for nut-fastening tasks within a strict 76-second factory cycle over 3 hours of operation.
By using tactile gloves for direct data collection, theyโve open-sourced the TacRefineNet framework and 61 hours of raw data to accelerate embodied AI development globally.
Full-palm tactile sensing paired with active liquid cooling might be the missing link for putting humanoids into 24/7 heavy industrial roles.
What's your take on "sweating" robots as the solution to motor overheating in high-dexterity hands?
