Documentation
Build and operate Isaac Sim workflows from the browser.
Workflows when you want an agent to build it, sessions when you want your hands on it, the SDK when you want to script it.
01 · Workflows
Let an agent build, judge, and save a simulation
The highest-level path: a prompt in, a verified scene out.
02 · Sessions
Hands-on Isaac Sim through viewer, SSH, or MCP
A live GPU workspace you can save as a versioned environment.
03 · Python SDK
Programmatic training, sampling, and Behavior CI
Install, authenticate, run readiness checks, launch training.
Guide
Launch a workflow
Choose a session mode, describe the simulation, let the agent build and judge it, then inspect the result. A first run takes a few minutes.
Open the workflow builder →Choose where the agent works
New session for a fresh managed Isaac runtime, Existing session to attach to a ready session, or From env to start from a saved environment.
Write the simulation prompt
Describe the scene, robot, task, and success criteria. Keep prompts concrete: assets, positions, motions, constraints, and what the judge should verify.
Set the turn budget
Use a larger turn budget for rich scenes. Builder and judge attempts consume turns, so raise the budget for large or multi-step simulations.
Run and watch the trace
The run page shows allocation, sandbox startup, builder/judge progress, recent events, and the embedded viewer.
Use the result
Completed runs link back to the session and report saved USD paths, environment ids, screenshots, traces, and tool-call counts.
Guide
Operate a session
A session is the live Isaac Sim workspace: direct control, a browser viewer, session-scoped MCP tools, environment snapshots, and lifecycle actions.
View your sessions →Start a session
Open Sessions and choose Start session. Pick a blank Isaac workspace, or start from a saved environment version.
Wait for Isaac readiness
The list and detail pages distinguish control-plane status from Isaac runtime readiness. Open the viewer only after Isaac is ready.
Open the WebRTC viewer
Use Open WebRTC viewer from the list or the viewer card on the detail page. If the browser blocks the popup, open the detail page first.
Connect tools
The detail page exposes SSH and Claude Code/MCP setup when supported. Copy commands from the page rather than inventing hostnames.
Save the workspace
For blank sessions, Save as environment creates a reusable environment. For environment-backed sessions, Publish creates a new version.
Sleep, wake, extend, or stop
Warm-pool sessions can sleep and wake. Direct sessions can be extended. Stop when done.
Python SDK
Install, login, doctor, train.
The SDK book covers installation, authentication, readiness checks, training loops, examples, and Behavior CI.
