Explore the UBTech Walker S2 humanoid robot—a 1.76 m industrial humanoid with 52 DOF, autonomous battery swap, and 24/7 operation for smart factories.
The Walker S2 is engineered with human-like proportions to operate in environments built for people: doorways, workstations, conveyors and factory floors. Its height (~1.76 meters) and anthropomorphic dimensions enable seamless interaction with human-oriented tools and spaces.
With 52 degrees of freedom (DOF) across its limbs and torso, the Walker S2 combines high mobility with proficient manipulation. It incorporates fourth-generation bionic arms and highly precise hands, enabling sub-millimeter precision in tasks such as grasping and assembly.
Its motion repertoire includes anthropomorphic walking, waist rotation up to ±162°, reaching within 0-1.8 meter workspace, and transporting loads up to 15 kg.
A standout feature is the dual-battery system and hot-swap capability. Walker S2 can autonomously navigate to a dedicated battery swap station, remove the depleted pack and insert a fresh one—all without human intervention—enabling continuous operation in industrial workflows.
The robot includes dual-RGB stereo vision cameras for binocular depth perception and a force-feedback joint network that enables environment sensing and dynamic stabilization. It runs UBTech’s proprietary AI stack (Co-Agent / BrainNet) for task planning, exception handling and autonomous decision-making.
Artificial Intelligence & Task Planning: Walker S2 uses UBTech’s Co-Agent system and BrainNet 2.0 for multimodal reasoning and autonomous control.
Dynamic Motion & Balance Control: The full-body dynamic balancing algorithm supports complex movements, such as pitching up to 170° and maintaining stability under perturbation.
Vision & Sensor Fusion: Dual-RGB stereo vision offers human-like depth perception; additional proprioceptive and force-feedback sensors support manipulation and balance.
Power Management & Swapping: The dual battery bays, autonomous swap mechanism and scheduling algorithm allow for near-non-stop operation.

Designed for industrial deployment, Walker S2 can operate on production lines, transport components, perform quality inspections and collaborate with human workers. Its human-form enables access to workstations built for humans without extensive reconfiguration.
The dexterous hands and mobile locomotion allow Walker S2 to pick parts, load/unload bins, and navigate multi-level storage systems, enhancing automation in logistics centres.
Though focused on industrial use, the robot’s form factor also allows deployment in customer-interaction roles such as automated reception, guidance in large venues or 24/7 service kiosks.
As an advanced humanoid platform, Walker S2 serves research institutions as a base for studying human-robot collaboration, autonomous systems and advanced perception.
True 24/7 Operation: Autonomous battery swap reduces downtime and supports continuous deployment.
Human-compatible Form: Enables integration into environments built for humans without major infrastructure changes.
High Precision Manipulation and Load Handling: Up to 15 kg payload and fine motor control expand its operational range.
Autonomous Decision-Making: The integrated AI stack supports high-level task planning and adaptive behaviour.
Potential for Scalability: The design suggests readiness for mass deployment in smart factories and automation ecosystems.
Compared to other humanoid robots like Boston Dynamics’ Atlas or Agility Robotics’ Digit, the Walker S2 prioritises payload capacity, human-environment compatibility and continuous operation via hot-swapping batteries. While Atlas emphasizes extreme mobility and acrobatics, and Digit focuses on logistics tasks like box handling, Walker S2 targets industrial deployment with human-like reach and sustained uptime.
Walker S2 is positioned as an industrial-class humanoid robot; reported pricing is approximately US$ 80,000 for early access or prototype configurations. Actual commercial availability may be limited initially and often requires direct negotiation with UBTech or authorised integrators. Customised configurations and enterprise software/service packages may increase cost substantially.
