Walker S2 is an industrial humanoid from UBTECH for production and logistics work. It swaps its own battery in at most three minutes, lifts 15 kg and works anywhere from floor level up to 1.8 m.
Overview
Legged (bipedal)
Walker S2 is an industrial humanoid robot from UBTECH, designed for work in production and available for series production and delivery. It can swap its battery by itself without human help, pulling out and inserting the pack with both hands, so it can work continuously. Because it has two batteries, it can run on one while swapping the other, and depending on the urgency of the current task it decides whether to swap the battery or charge it. A powerful waist motor gives it a large rotation in both directions, a deep forward bend and a squat, so it can pick items off the floor and reach further with a load. The head uses two ordinary colour cameras as a pair of eyes and a learned depth model for real time 3D perception. On the software side it uses the UBTECH industrial agent Co-Agent together with the BrainNet 2.0 system, which coordinates several robots as a team on a production line.

What it can do
Walker S2 goes to the swap station by itself, removes the battery and inserts a charged one. With two batteries it can run on both or on one, and depending on task priority it decides itself whether to swap or charge. The manufacturer states continuous 24/7 operation with battery swapping.
A powerful waist motor lets Walker S2 rotate its torso ±162° and tilt it from +90° to -35° while carrying 15 kg. That way it reaches the floor and further to the side.
Whole body balance control lets Walker S2 squat deep and bend its torso up to 125°. It carries loads up to 15 kg anywhere in a working range from 0 to 1.8 m.
A pair of RGB cameras in the head works like two eyes. The UBTECH stereo vision system uses deep learning to build a detailed depth map in real time, from camera images alone.
Each hand has 11 degrees of freedom and six tactile sensors. One hand grips up to 7.5 kg, and the fingers alone hold 1 kg.
Walker S2 supports large language models for voice interaction. It has a 4 inch round face display, four microphones and two speakers.
