**Isaac Lab** is a GPU-accelerated, open-source framework designed to unify and simplify robotics research workflows, such as reinforcement learning, imitation learning, and motion planning. Built on [NVIDIA Isaac Sim](https://docs.isaacsim.omniverse.nvidia.com/latest/index.html), it combines fast and accurate physics and sensor simulation, making it an ideal choice for sim-to-real transfer in robotics.

Isaac Lab provides developers with a range of essential features for accurate sensor simulation, such as RTX-based cameras, LIDAR, or contact sensors. The framework's GPU acceleration enables users to run complex simulations and computations faster, which is key for iterative processes like reinforcement learning and data-intensive tasks. Moreover, Isaac Lab can run locally or be distributed across the cloud, offering flexibility for large-scale deployments.


## Key Features

Isaac Lab offers a comprehensive set of tools and environments designed to facilitate robot learning:
- **Robots**: A diverse collection of robots, from manipulators, quadrupeds, to humanoids, with 16 commonly available models.
- **Environments**: Ready-to-train implementations of more than 30 environments, which can be trained with popular reinforcement learning frameworks such as RSL RL, SKRL, RL Games, or Stable Baselines. We also support multi-agent reinforcement learning.
- **Physics**: Rigid bodies, articulated systems, deformable objects
- **Sensors**: RGB/depth/segmentation cameras, camera annotations, IMU, contact sensors, ray casters.

## Isaac Sim Version Dependency

Isaac Lab is built on top of Isaac Sim and requires specific versions of Isaac Sim that are compatible with each release of Isaac Lab.
Below, we outline the recent Isaac Lab releases and GitHub branches and their corresponding dependency versions for Isaac Sim.

| Isaac Lab Version             | Isaac Sim Version |
| ----------------------------- | ----------------- |
| `main` branch                 | Isaac Sim 4.5     |
| `v2.1.1`                      | Isaac Sim 4.5     |
| `v2.1.0`                      | Isaac Sim 4.5     |
| `v2.0.2`                      | Isaac Sim 4.5     |
| `v2.0.1`                      | Isaac Sim 4.5     |
| `v2.0.0`                      | Isaac Sim 4.5     |
| `feature/isaacsim_5_0` branch | Isaac Sim 5.0     |

Note that the `feature/isaacsim_5_0` will contain active updates and may contain some breaking changes
until the official Isaac Lab 2.2 release.
It currently requires the [Isaac Sim 5.0 branch](https://github.com/isaac-sim/IsaacSim) available on GitHub built from source.
Please refer to the README in the `feature/isaacsim_5_0` branch for instructions for using Isaac Lab with Isaac Sim 5.0.
We are actively working on introducing backwards compatibility support for Isaac Sim 4.5 for this branch.
