Isaac Sim

NVIDIA Omniverse™ Isaac Sim, is a scalable robotics simulation application and synthetic data generation tool, built on the NVIDIA Omniverse™ platform. It leverages Omniverse Kit powerful simulation technologies including advanced GPU-enabled physics simulation and photorealism with real-time ray tracing.

Isaac Sim is a physically accurate virtual environment to develop, test, and manage AI-based robots, and provides the essential features for building virtual robotics experiments including:

Tools for importing and simulating robot models, and simulating sensors such as RGB-D, PhysX-Lidar, RTX-Lidar, Radar, contact and IMU

Support for various robotics applications including navigation, manipulation, and AI applications through Python and ROS

Extensive tools for AI applications such as Isaac Replicator for synthetic data generation and domain randomization and Isaac Lab for robot learning

Extensions for building a warehouse such as sim-ready assets, conveyor tools, peoples and CuOpt for logistics and route optimization

Development tools, Isaac Core API is a robotics abstraction layer which hides the USD complexity

This release is offered as a container that runs locally or on RTX equipped Amazon Web Services (AWS), Microsoft Azure or Google cloud (GCP) with streaming to the user’s desktop. This cloud-based delivery provides the latest RTX graphics and performance to any desktop system without requiring local NVIDIA RTX GPUs.

What's New in Isaac Sim 4.5.0

General

  • Updated to Kit 106.5.0
  • Improved URDF and MJCF Importer functionalities
  • Renamed and refactored Isaac Sim extensions to standardize naming
  • Release Isaac Sim App Template GitHub repository
  • Simplified application configs to improve startup time
  • Improved workflow for inference isaac lab policies in Isaac sim

PhysX

  • Updated Omniverse Physics Manual with more information on USD API and features, and tuning and debugging robot simulations.
  • Improved inverse dynamics support for floating-base articulations, namely for gravity and coriolis compensation forces, and mass-matrix computation. Added new API for computing
    • the center of mass of an articulation and
    • the centroidal momentum matrix for whole-body robot control
  • Signed-Distance-Field (SDF) triangle-mesh colliders are now supported on CPU for higher small-scene performance.
  • Articulation mimic joints can now be configured to be compliant constraints which can help with simulation stability, in particular in robot manipulation scenarios.
  • OmniPVD
    • Pre/Post-Simulation State Capture: Added functionality to capture pre- and post-simulation states, aiding in debugging issues caused by user inputs before simulations. A new dedicated timeline, allowing a more precise inspection, control of pre- and post-simulation state, play-back and easy switching between pre-post simulation modes.
    • Error Stream Capture: Implemented error stream capture to correlate simulation states with error messages.
  • Bugfixes
    • Momentum conservation in GPU simulation: Many-to-one articulation/rigid-body interactions are now momentum conserving.
    • Fixed issue where articulations could miss collisions if the scene contained other articulations with self-collision enabled.
    • Fixed a simulation discrepancy between GPU and CPU for contacts involving mechanisms joined by D6 joints.
    • Fixed reported accelerations being zero after using inverse dynamics computations on GPU.

Replicator

  • A modular behavior scripting workflow enabling reusable, persistent, and configurable behaviors for synthetic data generation.
  • Tutorial for setting up a synthetic dataset generation pipeline with procedurally generated environments from Infinigen, covering randomizations, physics simulations, and multi-camera data capture.
  • Getting started examples and setup for common Isaac Sim Replicator workflows.

Robots

  • Official thumbnail for robot, sensor and prop assets.
  • Variant implementation for new robotic assets for animation, physics simulation and sensor simulation use cases.
