Psi V1 vs Isaac 1
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 Isaac 1? What the published figures say
assembled from the figures below — no score, no ranking, no winner
Of the 21 measurements both robots publish, the printed values differ on 17 and are identical on 3.
6 of them are one number against another — Psi V1 prints the higher figure on 4, Isaac 1 on 2 — and the other 11 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 2.9% higher at against Isaac 1's .
On weight, Psi V1 is 3.8× higher at against Isaac 1's .
On degrees of freedom, Psi V1 is 2× higher at against Isaac 1's .
Psi V1's source states that figure as a maximum rather than a typical figure, so the gap is not a like-for-like difference.
On runtime both publish , but Psi V1's source states it as a minimum rather than a measured figure — the same number, stated differently.
They are not equally well sourced: on height the Psi V1 figure comes from PsiBot's own pages, while the Isaac 1 figure is published only by third-party directories.
Psi V1 publishes rated payload — — and Isaac 1 does not.
Isaac 1 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 17 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.
Isaac 1
Isaac 1 is a preorder wheeled humanoid from Weave Robotics, designed in United States. Its page publishes 44 of 195 sourced specifications, 28 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.
