Genesis is a comprehensive physics simulation platform designed for robotics, embodied AI, and physical AI applications. It is a general-purpose physics engine built from the ground up to simulate a wide range of materials and physical phenomena. As a lightweight, ultra-fast, Pythonic, and user-friendly simulation platform, it also features a powerful realistic rendering system and a data generation engine that converts natural language descriptions into various data modalities. By integrating its core physics engine, Genesis enhances the upper-level generative agent framework, aimed at achieving fully automated data generation for robotics and beyond.
