Menlo/asimov-1-simready-usd

Asimov 1 — SimReady USD

USD simulation asset for the Asimov 1 humanoid robot, prepared against the SimReady Robot-Body profile. This dataset contains the packaged USD asset and its validation, benchmark, and packaging metadata—not the full engineering source repository.

Robot overview

Specification	Value
Robot type	Humanoid
Project height	Approximately 1.2 m
Nominal project mass	35 kg
Actuated degrees of freedom	25

Height and nominal mass are project specifications, not newly measured simulation dimensions. The authored USD body masses sum to approximately 35.525 kg. The package provides the robot asset, not a balance or locomotion controller.

Download and open in Isaac Sim

With the Hugging Face CLI installed, download the complete package:

hf download Menlo/asimov-1-simready-usd \
  --repo-type dataset \
  --include 'asimov_1/*' \
  --local-dir ./asimov-1-simready

If access requires authentication, run hf auth login first. The download includes the configuration layers, hidden metadata and thumbnail directories; preserve their relative paths rather than copying only the root USD.

1. Launch Isaac Sim (tested with 6.1.0.0).
2. Choose File → Open and select asimov-1-simready/asimov_1/simready_usd/asimov_1.usd beneath your download location.
3. To integrate the robot into an existing scene instead, add the root USD as a reference and configure the surrounding scene separately.

This opens the robot asset, not a complete simulation application. Supply ground, lighting and physics-scene settings as needed for your use case. Opening the USD or pressing Play does not provide a balance or locomotion controller. Validate the behaviour you need in your own engine and scene before relying on it.

Materials reference NVIDIA's runtime-provided OmniPBR.mdl, which is intentionally not redistributed here. Use an Isaac Sim/Omniverse installation that supplies that runtime library.
