Webots is a free and open-source 3D robot simulator developed by Cyberbotics. It is designed to model, simulate, and control mobile robots, manipulators, and drones in complex physical environments. Widely used in education, academic research, and industry, Webots supports realistic physics, customizable robots, and integration with AI frameworks.

The simulator allows users to prototype and test algorithms for control, perception, and reinforcement learning before deploying to physical robots. It includes a library of prebuilt robot models, supports multiple programming languages, and provides seamless integration with real-world robot platforms.

Key benefits:

• Realistic physics and environment modeling

• Extensive support for robot hardware and sensors

• Cross-platform, open source, and continuously maintained
