NVIDIA Isaac Sim is a USD based simulator built on the Omniverse stack, with PhysX 5 for dynamics and RTX ray tracing for camera and lidar data close to the real thing. Version 5.0 arrived in 2025 with neural reconstruction, a new sensor schema and a source tree on GitHub under Apache 2.0, so the application can be built and modified locally. Paired with Isaac Lab, it is the usual starting point for reinforcement learning on manipulators and humanoids.
The price of that realism is hardware. Documentation asks for an RTX class GPU with about 16 GB of video memory, 32 GB or more of system RAM, Ubuntu 22.04 and newer or Windows 11. Nucleus and the old Omniverse Launcher were dropped after 4.5, which changed setup habits for existing teams. A fine choice for AI robotics groups with a workstation budget, a poor one for a laptop classroom or for writing a RAPID program by Friday.
