UBTech Walker S2
Full-size industrial humanoid from UBTech that swaps its own battery in about three minutes, sold to car plants, factories and logistics sites.
Mass production and delivery began in late 2025, with orders above 800 million yuan from factories and logistics firms.
Excellent humanoid robot (84/100). It stands out most for mobility (dof) (100/100). Highlight: autonomous battery swapping. Main trade-off: no public price.

Owner reviews
A top-tier humanoid robot we recommend without hesitation
In our independent assessment, the UBTech Walker S2 earns 84/100 — an excellent humanoid robot.
Its strongest area is mobility (dof) (100/100), followed by availability (100/100). In practice, autonomous battery swapping.
The main caveat is dexterous hands, where it scores 84/100. Specifically, no public price.
For most buyers in this category, it's one of the best choices you can make.

Can I actually buy a humanoid robot?
Yes, but mostly research and developer models (Unitree, Booster, EngineAI and others) that ship today. Most general-purpose humanoids are still in paid pilots, pre-order or prototype: check the Availability line before you plan around one.
How much does a humanoid robot cost?
Small developer humanoids start at a few thousand euros; full-size research platforms start around 17,000 € and advanced ones reach about 100,000 € or more. Industrial humanoids are usually sold or leased on quote, so no public price is listed.
What can humanoids do today?
Current models walk, balance, carry modest payloads and perform scripted, learned or teleoperated tasks. Fully autonomous household help is still emerging.
What do degrees of freedom (DoF) tell me?
Each DoF is one joint axis the robot can move. More DoF, especially in the hands, means more dexterous manipulation, but also more to calibrate and maintain.
Do they come with an SDK?
Research-focused humanoids ship with an open SDK or ROS support for programming and experiments; commercial units are typically locked to the vendor's software.
