Walker S2

Evidence ready S2

EVIDENCE READY — all evidence conditions met. This describes our evidence, not the machine.

Branded identity panel for the Walker S2 by UBTECH Robotics. This is a graphic generated by Physical AI Radar, not a photograph of the robot.
Capability 12.0 What it has been shown to do
Commercial reality INSUFFICIENT DATA Insufficient data is not a score of zero and is not better or worse than one — this dimension could not be calculated at all. Whether anyone pays for it
Evidence confidence 75.3 High — how much to trust the two numbers left
Research completeness 41.0% of our research checklist

These are four separate answers and are never combined. A calculated 0.0 means we scored the dimension and nothing earned credit; insufficient data means we could not calculate it at all. Neither ranks above the other. What this means →

Why these scores

Capability is 12.0 because 3 publication-eligible claim(s) fall in capability categories that carry weight for a humanoid robot. Only the strongest claim in each category counts. Commercial Reality is INSUFFICIENT DATA because no deployment has been recorded for this robot. Retail availability is not a deployment. Evidence Confidence is 75.3 (High) from 3 publishable claim(s), of which 3 are score-bearing.

Capability evidence

What the evidence actually establishes.

Only the strongest claim in each capability category earns credit. A claim can be publishable and still carry no score credit.

Autonomous Task Execution

No credit

NCSTI/Beijing E-Town government portal explicitly documents Walker S2 autonomous hot-swappable battery exchange: 'can autonomously choose battery replacement or recharge based on task priorities without shutdown or human intervention.' Government/Regulatory / Independent. Fully Autonomous mode is directly stated in source — this is NOT an inference. Technical capability evidence only; no customer, payment or production-deployment inference.

T2 - Independently Demonstrated Mode: Fully Autonomous SRC-000054

Mobility

No credit

Nanshan District Government (Shenzhen) reports three Walker S2 robots performed at the 15th National Games opening ceremony, characterized as 'fully autonomous,' striking ancient bronze bells. Government/Regulatory / Independent. Three-unit public event, independently observed and documented. FA mode explicitly stated by government source. Locomotion in public event confirmed. Not industrial deployment.

Commercial reality

Who is paying, and what is actually running.

Contracted units and verified production units are different facts and are kept in different fields. Nothing here implies progression that has not happened.

No recorded deployments

No qualifying commercial deployment has been evidenced for this robot.

Specifications

Manufacturer-stated figures.

Specifications are what a manufacturer states. Verification status is shown for each.

No specifications recorded

No manufacturer specification has been captured for this robot yet.
