UBTech Walker S vs Unitree H2

Both humanoids read on the same 8 axes and 40 sub-axes, using the published Index scores. Every difference below carries the public evidence behind it, and sub-axes with no public evidence count as 0 rather than being skipped.

The public record is still thin on at least one side of this pair, so treat the ordering as provisional rather than settled.

The short answer

UBTech Walker S scores 0.92 higher than Unitree H2, but that lead rests mostly on vendor claims and demos.

Only 8% of UBTech Walker S's score is carried by independently verified material — the rest is claimed or shown in demos. Unitree H2 has more unscored ground than the gap between them, so this could change next month.

Where Unitree H2 is ahead

Not ahead by enough on any axis to be worth reporting.

What would change it

14 sub-axes on the trailing side have no public evidence yet. If all of them scored full marks they would be worth 1.75 — against a gap of 0.92.

There is more unscored ground than there is gap, so this result could turn over after the next research month.

Each wheel has 40 spokes — five per axis. A longer spoke is a higher score, and the dashed rings mark 1 to 4. Hover or tab onto any spoke to read the axis, the sub-axis and the exact value. A missing spoke means there is no public evidence for that sub-axis yet, which is not the same as scoring zero. The faint outline on each wheel is the other humanoid, drawn on the same scale.

What this comparison cannot settle

Neither humanoid has a public read on 9 of the 40 sub-axes, so those cannot be compared at all.
16 sub-axes are read on only one side. A one-sided cell is undecided, not a zero for the silent side.
Most of UBTech Walker S's score rests on vendor statements and demo footage rather than independently verified material (8% carried by verified evidence).
Most of Unitree H2's score rests on vendor statements and demo footage rather than independently verified material (6% carried by verified evidence).
Demonstrations happen in different environments and product revisions are not always equivalent, so like-for-like uptime and throughput figures do not exist for most of the field.
