**Isaac Lab** is a unified and modular framework for robot learning that aims to simplify common workflows
in robotics research (such as reinforcement learning, learning from demonstrations, and motion planning). It is built upon
`NVIDIA Isaac Sim`_ to leverage the latest simulation capabilities for photo-realistic scenes, and fast
and efficient simulation.

The core objectives of the framework are:

- **Modularity**: Easily customize and add new environments, robots, and sensors.
- **Agility**: Adapt to the changing needs of the community.
- **Openness**: Remain open-sourced to allow the community to contribute and extend the framework.
- **Battery-included**: Include a number of environments, sensors, and tasks that are ready to use.

Key features available in Isaac Lab include fast and accurate physics simulation provided by PhysX,
tiled rendering APIs for vectorized rendering, domain randomization for improving robustness and adaptability,
and support for running in the cloud.

Additionally, Isaac Lab provides over 26 environments, and we are actively working on adding more environments
to the list. These include classic control tasks, fixed-arm and dexterous manipulation tasks, legged locomotion tasks,
and navigation tasks. A complete list is available in the `environments <source/overview/environments>`_ section.

The framework also includes over 16 robots. If you are looking to add a new robot, please refer to the
:ref:`how-to` section. The current list of robots includes:

- **Classic** Cartpole, Humanoid, Ant
- **Fixed-Arm and Hands**: UR10, Franka, Allegro, Shadow Hand
- **Quadrupeds**: Anybotics Anymal-B, Anymal-C, Anymal-D, Unitree A1, Unitree Go1, Unitree Go2, Boston Dynamics Spot
- **Humanoids**: Unitree H1, Unitree G1
- **Quadcopter**: Crazyflie
