Xiaomi’s bionic hand redesigned to human size, aims for factory-ready durability

Overview

Xiaomi (小米) has unveiled a major redesign of its bionic hand, reportedly shrinking the actuator pack and casing by about 60% to match the dimensions of a human worker's hand and positioning the device for industrial use. Built on learnings from the Xiaomi CyberOne platform, the team says the new prosthetic-style manipulator now offers full-palm tactile coverage and has been stress-tested in long-duration grip cycles. Can a smaller, human-proportioned robotic hand bridge the gap between lab demos and real factory floors? Xiaomi clearly thinks so.

Technical advances

It has been reported that the redesigned hand measures roughly 187mm × 88mm × 36mm (down from 228mm × 105mm × 64mm) and increases tactile sensor coverage to about 8,200 mm². The team says the mechanism sustained more than 150,000 repeated grasp cycles in real-world tests — a 61-hour unaccelerated test video has been published — and that the device includes a “bionic sweat gland” evaporative cooling system. Reportedly the active cooling can evaporate about 0.5 ml of water per minute and deliver roughly 10 W of heat removal via metal 3D‑printed liquid channels and a micro‑pump. For data-driven control, engineers are using full-hand tactile gloves to collect human grasping data, feed it into simulation and train imitation and reinforcement-learning policies; related models and code (including TacRefineNet and Xiaomi‑Robotics‑0) have been made available on GitHub.

Context and implications

This effort fits a broader push in China to industrialize advanced robotics and close gaps in hardware and algorithms as the country seeks greater autonomy in manufacturing technology amid global supply‑chain frictions and export controls. It has been reported that Xiaomi hopes these optimizations will push task success rates “close to 100%,” though independent validation will determine whether the device can meet the durability, maintenance and safety requirements of high‑volume assembly lines. For Western readers: open‑sourcing parts of the stack and publishing raw test footage are moves designed to build credibility quickly. The real test will be scale — can this human‑sized hand be produced, maintained and integrated at the throughput factories demand?
