What it is
CyberOne (known in Chinese as "Tieda") is the first full-size humanoid bionic robot from Xiaomi Group, unveiled on August 11, 2022 at Lei Jun's annual speech. It stands 177 cm tall, weighs 52 kg, and has 21 joint degrees of freedom across its body, with response latency per degree of freedom as low as 0.5 ms. It appeared in public roughly two months before Tesla's Optimus prototype, making Xiaomi one of the earliest Chinese companies to put a full-size humanoid engineering prototype on the ground at the time.
