Cloud Isaac Sim

Learn how to run cloud Isaac Sim integrated with OM1

Cloud Isaac Sim Developer Walkthrough

Cloud Isaac Sim enables you to run robot simulations on managed cloud infrastructure, fully integrated with OM1. This guide walks you through launching an instance and connecting your OM1 setup.

Prerequisites

• OpenMind Portal account on Builder plan or higher (required for Cloud Simulator access)

• API key (found in your portal)

• OM1 codebase with uv environment configured

Cost & Billing

Cloud Simulator usage is billed in OMCU (OpenMind Compute Units). Billing begins as soon as an instance is allocated and stops only when the instance is deleted. Ensure your account has sufficient balance before launching.

A Builder plan or higher is required to access the Cloud Simulator. Check your OMCU balance and plan in the OpenMind Portal dashboard before starting.

Step 1: Launch a Cloud Simulator Instance

1. Log in to the OpenMind Portal

2. Navigate to Cloud Simulator from the sidebar

Instance Types

Choose based on your simulation workload:

Instance Type	vCPUs	RAM	Best For	Price (Per Hour)
Standard	8	32 GB	Development & testing	4800 OMCU
Performance	16	64 GB	Heavy compute, multi-robot scenarios	7200 OMCU

Supported Robots

• Unitree Go2

• Unitree G1

• LimX Tron

Available Environments

• Warehouse

• Apartment

Launch Time

The instance goes through the following stages before it is ready:

1. Allocating Instance

2. Load Robot Configuration

3. Launching Simulator

4. Render Environment

5. Finalizing Simulator Setup

Note: Expect 10-15 minutes for your instance to fully initialize.

Once you initiate the launch, the system begins setting up your cloud environment.

The instance is ready when the status changes to Running.

Note: If the requested GPU is not available, you will see the error below. Wait a few minutes and try again, or switch to a different instance type.

Step 2: Access your Active Cloud Isaac Sim Session

View your running session from the portal dashboard.

Click on Open Session. The simulator view will reflect the robot you selected when launching the instance:

Unitree Go2:

Unitree G1:

LimX Tron:

Step 3: Run OM1 with Cloud Simulator

Two options are available once your instance is running:

Option A: Cloud VS Code

Access a full VS Code environment running in the cloud with OM1 pre-configured.

From here, you can:

• Edit and run OM1 code directly in the cloud

• Execute uv run commands without local hardware

• Test and debug your robot behaviors

Option B: Local Environment

Run OM1 on your local machine and connect to the cloud simulator:

1. Copy your API Key from the portal and ensure OM_API_KEY is set in your environment or .env file.

2. Open config/cloud_sim.json5 in your local OM1 repo. This config targets a Unitree Go2 in the cloud simulator with voice input, VLM, and autonomous movement. You can adjust the system_prompt_base, robot inputs, and actions to match your use case.

3. Run the config:

uv run src/run.py cloud_sim

Cleaning Up

When you're finished with your simulation:

1. Return to the Cloud Simulator dashboard

2. Click Delete Instance

1. Confirm the deletion — this stops billing and frees cloud resources
