H1 vs G1: human-scale and compact Unitree platforms
Physical scale is clear in the manufacturer evidence; comparable task performance is not.
Source review: 21 October 2026 · Manufacturer claims are not independent test results.

Keep H1 separate from H1-2
Unitree lists H1 at about 1.8 m and 47 kg. The same page includes H1-2 at about 1.78 m and 70 kg; H1-2 figures must not be attributed to the catalogue’s H1 profile.
Standard G1 is listed at 1.32 m and about 35 kg with battery, with 23 degrees of freedom.
Locomotion claims versus laboratory evidence
The H1 page publishes 3.3 m/s moving speed and separately labels more than 5 m/s as potential mobility. Potential mobility is not an achieved operational specification, and neither value establishes sustained performance under a buyer’s conditions.
There is no matched manufacturer test here establishing which robot performs a particular research task better. Check available reach, control interfaces, test-space clearances and recovery procedures rather than ranking demonstration clips.
Match hardware and access to the experiment
G1’s developer configurations are separately identified in Unitree’s SDK documentation. Do not infer that standard G1 includes the EDU development package.
Request the exact H1 generation, controller access, end effectors and support scope in writing. Trial the required experiment with appropriate fall protection and risk assessment; no purchase availability or industrial readiness is established here.
