Walker S2 is UBTECH's second-generation industrial humanoid, built around a dual-battery system that keeps the robot powered while it exchanges a depleted pack, giving effectively continuous operation. It lifts 15 kilograms, works from floor level to 1.8 metres for stoop lifting, and its high-torque waist servo rotates plus or minus 162 degrees and pitches 125 degrees. Binocular stereo vision with RGB cameras handles part location, and UBTECH's fleet software coordinates groups of robots on a line. UBTECH has announced large order books from Chinese automotive and electronics manufacturers, and earlier Walker S1 fleets worked at Zeekr and Foxconn sites.
