Psi V1 vs RB-Y1
One row per spec, aligned across 2 robots. A hatched cell means neither the maker nor the directories we read publish that value.
Psi V1 or RB-Y1? What the published figures say
assembled from the figures below — no score, no ranking, no winner
Of the 26 measurements both robots publish, the printed values differ on 20 and are identical on 6.
8 of them are one number against another — Psi V1 prints the higher figure on 6, RB-Y1 on 2 — and the other 12 differ in kind rather than in magnitude: a list, a yes/no, a range, or the same quantity printed in a different unit.
On height, Psi V1 is 29% higher at against RB-Y1's .
On weight, Psi V1 is 15% higher at against RB-Y1's .
On degrees of freedom, Psi V1 is 75% higher at against RB-Y1's .
Psi V1 has figures its sources state as a bound rather than an exact value, so those gaps are not like-for-like.
They are not equally well sourced: on height the Psi V1 figure comes from PsiBot's own pages, while the RB-Y1 figure is published only by third-party directories.
Psi V1 publishes walking speed — — and RB-Y1 does not.
RB-Y1 publishes DoF per arm — — and Psi V1 does not.
The most important differences
ranked by how much of the catalogue publishes the measurement
The 5 most widely published of the 20 measurements where these two differ — ranked that way because a figure most of the catalogue publishes is one that means the same thing on both sides. Every value carries the source that states it.

What each one is
from each robot's own published columns
Psi V1
Psi V1 is a wheeled humanoid from PsiBot, designed in China. Its page publishes 42 of 195 sourced specifications, 5 of them from the maker.
RB-Y1
RB-Y1 is a preorder wheeled humanoid from Rainbow Robotics, designed in South Korea. Its page publishes 61 of 195 sourced specifications, 23 of them from the maker.
No value in this table has been independently measured or filed with a regulator — every number is a claim by a maker or by a third-party directory, and the chip on each one says which.
