Introduction to Isaac Sim
Gazebo Sim and Webots may work on most PCs with average specifications. If you have these specs, you can use these simulators, but If you have a PC with high-end specifications such as 32 to 64 GB of RAM, NVIDIA RTX 40XX series graphics card with >=8 GB VRAM, and a high-end CPU, you can try out the NVIDIA Isaac Sim simulator [27]. NVIDIA Isaac Sim is an open-source application on NVIDIA Omniverse for developing, simulating, and testing AI-driven robots in realistic virtual environments [34]. The main difference NVIDIA brings is that it has a photorealistic, physics-accurate, and scalable simulation of robots. It is also integrated with NVIDIA GPU-accelerated technologies, which allows real-time rendering and physics-based simulation. Isaac Sim is used to collect datasets and train robot models.
It features good ROS 2 integration, allowing you to simulate complex scenarios that leverage the high-end capabilities of ROS 2. You can see the installation...
