Previous model: UBTECH Walker S1
Overview
UBTECH's second-generation industrial humanoid, built for factory and logistics work. It swaps its own battery in about 3 minutes using two hot-swappable packs, so it can run 24/7. A high-torque waist lets it lift 15 kg and bend to the floor. It has binocular stereo vision in the head, Jetson AGX Orin compute and UBTECH's BrainNet 2.0 / Co-Agent software for coordinating robot fleets.

Key facts
- UBTECH bills it as the world's first humanoid that swaps its own battery: about 3 minutes, using two hot-swappable batteries (ubtrobot.com Walker S2 page).
- Waist servo turns +/-162 deg; lifts 15 kg and handles 15 kg loads anywhere from 0 to 1.8 m (UBTECH).
- Numbers from Funduino's listing (UBTECH data): 176 cm; 70 kg without hands (70-95 kg depending on configuration); 52 DOF in total (30 active without hands); up to 7.2 km/h, <=2.5 km/h loaded.
- Batteries: 2x 48 V 9 Ah LiFePO4 (battery_wh 864 = 2 x 48 V x 9 Ah). Runtime: >=3.5 h in stepping mode, >=2 h in transport mode (battery_hours uses 2 h). Full charge <=3 h on the robot, <=2 h in the swap station.
- UBTECH's own S2 page shows a sensor diagram but no numeric spec table, so the numbers come from the reseller listing (source_type secondary).
