Isaac Sim 4.5 and Isaac Lab 2.0 is Now Available

Isaac Sim 4.5 [DOWNLOAD]

Isaac Sim 4.5 is now available. The 4.5 release offers a number of significant changes, including the following:

  • Renaming Extensions in Isaac Sim: With the release of Isaac Sim 4.5, extensions have been renamed and divided to enhance modularity, facilitating end-users in building custom applications using these extensions, including Isaac Lab. Users should ensure their code is updated to reflect the new extension names. Learn more.
  • A reference application template: Isaac Sim has been redesigned as a customizable reference application. A minimal template for faster startup and a full template with complete functionality along with all dependencies. Additionally, users can take advantage of templates designed specifically for Synthetic Data Generation (SDG) and Software-in-Loop (SIL).
  • Improved URDF import and setup: User Interface has been simplified to provide a more streamlined process and align with how other formats are imported, making simulations more stable.
  • Improved physics simulation and modeling: Define and configure various joint types between robot components, setting parameters like stiffness and damping to fine-tune joint behavior.
  • New joint visualization tool: Enables you to inspect the physics properties of selected prims, including their position, rotation, linear and angular velocities, and accelerations.

NOTE: With significant changes to renaming and restructuring, users should ensure that the existing code uses the new extension names.

Isaac Lab 2.0 [DOWNLOAD]

A new 2.0 version of Isaac Lab is now available. The latest release includes new features, performance and usability improvements:

  • Imitation Learning Workflow: GR00T-Mimic in Isaac Lab enables developers to generate synthetic trajectories from captured human demonstrations
  • Tiled rendering: Improved tiled rendering performance by up to 1.2x and support for multiple TiledCamera instances of varying resolutions
  • Quality of life improvements: Simplified installation process using Python package managers and a new Isaac Lab container enabling the movement of workloads across systems without underlying dependencies.
  • Performance Improvements: Faster startup time through optimizations in the Cloner class that improves startup time by 30%.

NOTE: With significant changes to renaming and restructuring, users should update their workflows to prevent issues with their existing code.
