A wheeled base with lidar drives itself around the site; it is stable when stopped, so the arms can work without balancing.
A single 'leg' of six joints lifts and tilts the torso, giving the arms a human-like working range from floor to table height.
Seven joints per arm, like a human shoulder, elbow and wrist, let it reach around obstacles; each arm carries about 3 kg.
An optional leader arm lets a person guide the motions; researchers use those recordings to train AI control models.
