UBTECH Walker S2 Industrial Humanoid Robot

Most robots ask a factory to rebuild itself around them. The UBTECH Walker S2 Industrial Humanoid Robot asks for the opposite: it is built to walk into spaces made for people and keep working there, and it swaps its own battery so the shift does not have to stop.

The product is available through this page, by quotation.

Background

UBTECH and the Walker line

UBTECH builds humanoid robots, and the Walker family is its line of full-size walking machines. Walker S2 is the manufacturer's latest generation of industrial humanoid robots, launched as the newest step in that line. The earlier models are still part of the range, and buyers comparing generations can look at the UBTECH Walker S1 Industrial Humanoid Robot and the UBTECH Walker S Industrial Humanoid Robot. The wider family is gathered in the UBTECH Walker category.

The point of an industrial humanoid is simple to state. Factories, warehouses and production lines already have doorways, shelves, workstations and tools sized for the human body. A machine with a similar shape can, in principle, work among them without the site being redesigned. That idea is what the Walker line is built around.

Positioning and key technology

UBTECH positions Walker S2 as a new-generation industrial humanoid robot with autonomous battery swapping for 24/7 operation in manufacturing and material-handling workflows. The battery system is the feature that sets the tone. Most humanoid robots must stop and wait on a charger. Walker S2 is designed to exchange its battery on its own, and the swap time is 3 min.

The second pillar is the body. Walker S2 has 52 degrees of freedom, split across the arms, hands, legs, waist and neck. The hands carry the largest share, which matters for any task that involves picking up, holding and placing objects. Two six-axis force sensors add force feedback, and a wide waist range lets the upper body reach and bend in ways a rigid torso could not.

Walker S2 sits in the Bipedal Humanoids category, alongside other robots that walk on two legs rather than roll on wheels.

Technical Specifications

Specifications as published by the manufacturer; confirmed against the datasheet at quotation.

The manufacturer has not published the battery capacity, the runtime per charge, the ingress protection rating, the charge time, the wireless connectivity, the operating temperature range or the power consumption; they are confirmed at quotation.

What does autonomous battery swapping change on the factory floor?

A robot that must stop to charge is a robot that needs a schedule built around its weakness. Someone has to decide when it leaves the line, how long it is gone and who covers the gap. Autonomous swapping removes much of that planning. Walker S2 is designed to exchange its own battery in 3 min, so the interruption is short and does not need an operator at the charger.

That is why the manufacturer ties the robot to 24/7 operation in manufacturing and material-handling workflows. Continuous work is the goal, and the swap is the mechanism. For a buyer, the practical questions are about the surrounding setup: where the swap station sits, how many batteries the site needs and how long a battery lasts between swaps. Runtime per charge and battery capacity are open points that your quotation settles.

The body supports the same goal. With 11 degrees of freedom in each hand and a single hand grasp of 7.5 kg, the robot is aimed at handling work, not only at walking and demonstrating. A waist that rotates ±162° and pitches from +90 to -35 deg gives the upper body room to turn toward a conveyor, a bin or a shelf without the legs repositioning each time.

What does the Walker S2 EDU version add?

The sources name two versions: Walker S2 and Walker S2 EDU. For the EDU version, UBTECH offers a simulation model as a ROS and ROS 2 package, with URDF and STL files, in the repository named UBTECH-Robot/WalkerS2-Model. For teams that work in simulation, that matters. They can load the robot model, test motion and control ideas on a computer and prepare their software before a physical unit is in the room.

The figures in the table above are listed for Walker S2 and are not split by version in the sources. No other difference between the two versions is stated, so please ask for the exact scope of each when you request a quotation. Do not assume that a feature of one is present or absent in the other until you have it in writing.

Who is UBTECH Walker S2 for?

Manufacturers are the first group. Plants that run long or continuous shifts and have material-handling steps that are still manual can use Walker S2 to study how a humanoid fits into an existing line. The human-scale body, at 1.76 m and 70 kg, is meant for workstations and aisles built around people.

Logistics and warehouse operators are a second group. Moving items between stations is a task where hands, reach and a stable stance count, and the battery swap addresses the question of uptime.

Universities, research labs and integrators form a third group. Teams developing software for humanoids, particularly those who want to work in ROS or ROS 2, should ask about the Walker S2 EDU version and its simulation model. Training programs can use it to teach students how a full-size humanoid is structured and controlled.

Buyers who are still choosing a generation, or who want to compare against earlier Walker models, can review the earlier models named in the Background section before requesting a quotation.

What is UBTECH Walker S2 used for?

1. Manufacturing assistance: work at stations designed for people, in the production workflows the manufacturer names.
2. Material handling: moving and placing items with hands that can grasp 7.5 kg each.
3. Continuous operation: keeping a task running across shifts by swapping its own battery in 3 min.
4. Simulation and software development: using the URDF and STL package for the Walker S2 EDU version in ROS or ROS 2.
5. Research on humanoid control: studying walking, balance and whole-body motion across 52 degrees of freedom.
6. Education and demonstration: showing students and visitors how an industrial humanoid is built and how it works.

Frequently Asked Questions

How tall is the Walker S2 and how much does it weigh?

Height is 1.76 m and weight is 70 kg.

How many degrees of freedom does it have?

It has 52: 7 per arm, 11 per hand, 6 per leg, 2 in the waist and 2 in the neck.

How long does the battery swap take?

The swap time is 3 min, and the swap is autonomous. The robot exchanges its own battery.

How much can one hand lift?

The single hand grasp is 7.5 kg.

Is a simulation model available?

Yes, for the Walker S2 EDU version. UBTECH provides a URDF and STL package for ROS and ROS 2 in UBTECH-Robot/WalkerS2-Model.

What is the battery runtime or ingress protection rating?

The manufacturer has not stated either, nor the battery capacity, charge time, wireless connectivity, operating temperature range or power consumption. They are settled with your quotation.

Where can I buy the UBTECH Walker S2 and what does it cost?

You can request it through this page. The cost is given in a quotation prepared for your requirements, and delivery, customs and support are arranged with it.

Summary

Walker S2 is built on a simple bet: bring a human-shaped robot to a human-shaped workplace, then keep it running by letting it change its own battery. Its 52 degrees of freedom, six-axis force sensing, 7.5 kg single hand grasp and 3 min swap time make that bet concrete, and the EDU version adds a simulation model for software teams. Questions about runtime, protection and power are answered with the quotation, and this page is the starting point.
