Simulo for Cloud Robotics Simulation and Training

Train robot policies in simulation on managed cloud GPUs.

Simulo is a cloud-native AI platform for robotics simulation and training. Its lightweight simulo Python SDK and CLI let you define robot-learning applications locally, submit them to the Simulo cloud, and inspect the results. The platform handles managed GPU execution, reproducible packaging, versioned assets, checkpoints, trained models, recordings, and live 3D viewing.

The package installed on your computer is torch-free and requires no local GPU or simulator. The managed runtime currently uses NVIDIA Isaac Sim and Isaac Lab to execute reinforcement-learning training, policy evaluation and inference, and scripted robotics simulations.

What you can do

• Write robotics applications in ordinary Python against a small, stable API.
• Build vectorized reinforcement-learning environments and train robot policies with PPO.
• Start with validated catalog robots or publish your own OpenUSD (USD) and URDF assets.
• Continue training from the best or latest checkpoint produced by an earlier job.
• Evaluate policies, run inference, and export trained policies as verified ONNX bundles.
• Stream logs, retrieve results and outputs, capture MCAP rollout recordings, and watch a live 3D view.

Install

python -m pip install simulo

Simulo requires Python 3.11 or newer. One installation provides both the import simulo Python API and the simulo command-line interface.

Train a first policy

simulo create mybot
simulo login
cd mybot
simulo run app.py --frozen --strict-assets

simulo create writes a complete starter application to your machine without requiring a login or network connection. The default application trains a PPO policy on a validated cartpole asset. simulo run packages the source, resolves and pins its assets, submits the job, and follows its cloud logs.

Explore robotics samples

The public Simulo samples repository contains projects for cartpole, humanoid locomotion, JetBot navigation, Franka arm control, a bring-your-own URDF arm, and F1TENTH-compatible drift training. Its current published compatibility contract is simulo>=0.26.0,<0.27. Check the repository README for the supported SDK range before running a checkout.

Monitor jobs and retrieve artifacts

simulo jobs                       # list submitted jobs and status
simulo logs --follow              # stream the latest job's logs
simulo result                     # read the job's result
simulo models                     # list or download trained models
simulo export                     # export the best policy as verified ONNX
simulo recordings                 # download MCAP rollout recordings
simulo outputs                    # retrieve other saved outputs
simulo view                       # view a running --viewstream job in 3D
simulo cancel                     # stop a queued or running job

Commands that accept a job ID default to the latest job and tell you which job they selected.

Use versioned robot assets

simulo asset list --global
simulo asset inspect simulo/robot/cartpole:v1
simulo asset publish ./my-robot --kind robot

Simulo catalogs keep robot, world, and prop assets versioned and traceable. You can use validated global assets immediately or publish your own USD or URDF package for reuse across training, evaluation, and inference jobs.
