LimX Luna vs Unitree G1
One row per spec, aligned across 2 robots. A hatched cell means neither the maker nor the directories we read publish that value.
LimX Luna or Unitree G1? What the published figures say
assembled from the figures below — no score, no ranking, no winner
Of the 56 measurements both robots publish, the printed values differ on 37 and are identical on 19.
18 of them are one number against another — LimX Luna prints the higher figure on 15, Unitree G1 on 3 — and the other 19 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, LimX Luna is 21% higher at against Unitree G1's .
On weight, LimX Luna is 54% higher at against Unitree G1's .
On degrees of freedom, LimX Luna is 17% higher at against Unitree G1's .
Unitree G1 and LimX Luna have figures their sources state as a bound rather than an exact value, so those gaps are not like-for-like.
LimX Luna publishes open to developers — — and Unitree G1 does not.
Unitree G1 publishes available from — — and LimX Luna does not.
The most important differences
ranked by how much of the catalogue publishes the measurement
The 5 most widely published of the 37 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
LimX Luna
LimX Luna is a prototype bipedal humanoid from LimX Dynamics, designed in China. Its page publishes 70 of 195 sourced specifications, 36 of them from the maker.
Unitree G1
Unitree G1 is a general availability bipedal humanoid from Unitree Robotics, designed in China. Its page publishes 104 of 195 sourced specifications, 61 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.
