What it is

Walker X is the next-generation large humanoid service robot that UBTech Technology globally unveiled at the World Artificial Intelligence Conference (WAIC 2021) in Shanghai on July 7, 2021; it is also the fifth iteration of the Walker series. Compared with the previous-generation Walker, its height was reduced to 130 cm and its weight to 63 kg (14 kg lighter than the previous generation). It has 41 high-performance servo joints across its body and an all-round perception system covering multi-dimensional force sensing, multi-camera stereo vision, omnidirectional hearing, inertial sensing, and ranging.
