The humanoid arms have a 765 mm single-arm reach, a rated single-arm payload of 6 kg and a dual-arm task payload of 12 kg, with repeat positioning accuracy of ± 0.03 mm and a terminal speed of 1.8 m/s. End effectors are a 2-DoF gripper and a 20-DoF dexterous hand, and the wheeled chassis moves at 1 m/s. The perception layer includes a 2D LiDAR, three RGBD cameras, ultrasonic sensors, a single-point ToF sensor and a BEV surround-view camera. The robot is driven end-to-end by the fully in-house WALL-A manipulation foundation model with tens of billions of parameters, achieving autonomous perception, decision-making and action, and targets home service, research and education, commercial cleaning and logistics sorting.
