AirSim: A High-Fidelity Simulator for Autonomous Vehicles
AirSim, developed by Microsoft Research, is an open-source simulator for drones, cars, and more, built on Unreal Engine (with an experimental Unity release). It's a powerful tool for AI research, allowing experimentation with deep learning, computer vision, and reinforcement learning algorithms for autonomous vehicles. AirSim provides realistic visual and physical simulations, supporting both software-in-the-loop (SIL) simulation with popular flight controllers like PX4 & ArduPilot, and hardware-in-the-loop (HIL) simulation with PX4.
