The UBTECH Walker S is an industrial bipedal humanoid robot standing 170 cm and weighing 76 kg, built for factory deployment with 41 servo joints incorporating individual force feedback and a 15 kg payload per arm. It integrates LLM-based task planning via a Baidu partnership, U-SLAM semantic navigation with centimeter-level indoor accuracy, and MES system connectivity. The Walker S is proven in real-world production environments at NIO and BYD automotive manufacturing facilities, with orders exceeding $112 million USD by late 2025.

Released: 2021

Overview

Walker S2 targets round-the-clock factory work. A 52-DOF body, high-torque waist, and fourth-gen dexterous hands deliver sub-millimeter manipulation across a ~2 m workspace with up to 15 kg payloads. Dual-RGB stereo feeds a multimodal autonomy stack (BrainNet 2.0 / Co-Agent) for planning, exception handling, and coordinated actions—including autonomous battery removal, docking, and reinstall—so the robot can keep working through shift changes. Built for automotive and general manufacturing, Walker S2 emphasizes uptime, repeatability, and safe coexistence with people in real production environments.

Technical Highlights

All 41 joints use UBTECH's proprietary drive units integrating a frameless torque motor, precision harmonic reduction gear, integrated drive controller, and dual encoder. Unlike rigid industrial robots, the Walker S detects resistance and adjusts force output through whole-body force feedback, applying collaborative robot safety principles to a full bipedal platform. The U-SLAM system builds 3D semantic maps distinguishing object types (workstation, conveyor, human worker, tool rack), enabling dynamic rerouting.

Applications

The Walker S is deployed in automotive manufacturing for quality inspection (door locks, headlight alignment, fluid levels, panel fit), light assembly (trim parts, seat belt components, vehicle badges), and inter-station logistics. Real-world deployments include NIO vehicle manufacturing lines, BYD assembly plants (Walker S2 since mid-2025), Airbus trials in Germany, and operations in Saudi Arabia, Singapore, and Japan.
