The Isaac Sim 5.0 open-source early developer preview is here, and it’s packed with powerful new features and major enhancements designed to take your robotics simulations to the next level. Check out what’s new:
Isaac Sim source code availability: Isaac Sim-specific extensions are being open-sourced in a new public Github repository. This repository will serve as an early access that’s available to the community and provides new features through a public development branch. Note that components of Omniverse Kit remain closed source, and external contributions are not accepted at this time. To submit feedback and engage with the Isaac Sim community, join the Discord discussion here. Isaac Sim 5.0 documentation will be available soon.
Performance improvements: Workflows in Isaac Sim 5.0 will see performance boosts with NVIDIA Omniverse Fabric. This change provides a significant improvement to simulation speed. Additional optimizations will improve the performance of software-in-the-loop testing workflows on multi-GPU systems.
Robot models:
- Robot schema: A new robot schema allows articulation roots, links, and joints to be defined in USD, standardizing robot definitions.
- Expanded robot asset library: New robot models from a variety of robotics companies, and updates to all robot assets to adopt the new robot schema.
- Robot Import Wizard & Importer improvements: The robot importers have been refactored so that all imported robots will now leverage the new robot schema. Additionally, the brand new Robot Import Wizard introduces a streamlined, user-friendly experience that guides you step-by-step through the robot rigging and import process.
- Asset validation tooling: New tools to help diagnose USD-level issues in robot assets, with ongoing improvements planned.
Sensors:
- Sensor schemas: Isaac Sim is adopting the new OmniSensor USD schema, which will allow RTX Sensors to be more easily defined. Instead of relying on JSON configuration files, sensor attributes can be directly defined in USD.
- Improved depth sensor simulation: - A new depth sensor model enables more realistic stereo depth simulation, including disparity artifacts.
- New sensor models: Isaac Sim’s asset library has been expanded to include additional sensor models from multiple OEMs.
Data generation: A new writer for NVIDIA Omniverse Replicator is optimized for NVIDIA Cosmos Transfer input for users to easily generate and export high-quality synthetic data for ingestion. It supports standalone workflows and the Script Editor, and can be seamlessly integrated into existing Isaac Sim synthetic data generation scripts.
-
Grasp data generation: A new tutorial introduces a workflow for generating and testing multiple grasp candidates for object picking. The accompanying Extension enables automated generation of grasp candidates, simulates each grasp attempt, and records relevant success metrics.
-
MobilityGen integration: Capabilities from MobilityGen are being incorporated into Isaac Sim, allowing synthetic data to be easily generated for locomotion model training. The set of Extensions will allow users to control robots through tele-operation or with random trajectories, easily collect and manage data, and replay trajectories for synthetic data capture.
-
Action and event generation: A variety of new workflows are now available, which are tailored to help with synthetic data generation in large physical spaces:
-
Physical Space Event Generation allows incidents to be easily defined, such as objects falling from storage, spills, and fires.
-
Camera placement tooling helps determine camera coverage.
-
VLM Scene Captioning allows scene captions to be generated based on captions of individual objects and their relationships to one another.
Additionally, various improvements have been made to the existing Actor Simulation and Object Simulation synthetic data generation workflows.
PhysX:
- Advanced suction gripper: An improved suction gripper is being introduced which will support multi-point grasping. A tensorized version will also be made available, however, it is currently CPU-only.
- Improved actuator models: Actuator models will be improved to introduce performance envelopes, allowing users to have better control over velocity and torque limits. The new model will allow for improved sim-to-real transfer by allowing real-world system dynamics to be more faithfully captured. Per-DoF joint friction will also be supported.
ROS2:
- Jazzy support: Full support for ROS2 Jazzy Jalisco is coming in Isaac Sim 5.0.
- MoveIt 2 tutorial: The MoveIt 2 Tutorial, which was previously not functioning, has been fixed and is now actively maintained by the Isaac Sim team. Users can once again leverage MoveIt 2 in Isaac Sim to test their motion planning workflows.
- Simulation interfaces: Isaac Sim will support the ROS2 Simulation Interfaces standard. This standard was spearheaded by Robotec.ai and developed in collaboration with Gazebo, Open 3D Engine, and NVIDIA, providing a standardized interface for users to control their simulations from ROS2.
- ZeroMQ bridge: A new ZeroMQ bridge enables communication between Isaac Sim and external systems, serving as an example for how bridges can be created for custom middlewares.
Reinforcement learning policy inference example: An example will demonstrate software-in-the-loop testing of a humanoid using a policy trained in Isaac lab.
