Pegasus Simulator is a framework built on top of NVIDIA Omniverse and IsaacSim. It is designed to provide an easy yet powerful way of simulating the dynamics of vehicles. It provides a simulation interface for PX4 and ArduPilot integration, as well as a custom python control interface. At the moment, only multirotor vehicles are supported, with support for other vehicle topologies planned for future versions.
Check the provided documentation here to discover how to install and use this framework.
- 2024-11-01: Pegasus Simulator v4.2.0 is released for Isaac 4.2.0. This version is NOT compatible with older versions of Isaac Sim. This version includes a new experimental interface for Ardupilot integration, provided by open-source contributor Tomer Tiplitsky.
- 2024-08-02: Pegasus Simulator v4.1.0 is released for Isaac 4.1.0. This version is NOT compatible with older versions of Isaac Sim.

This simulation framework is an open-source effort, started by me, Marcelo Jacinto in January/2023. It is a tool that was created with the original purpose of serving my Ph.D. workplan for the next 4 years, which means that you can expect this repository to be mantained, hopefully at least until 2027.
