GR00T, Cosmos, and Isaac Lab are getting a lot of attention as Physical AI frameworks, but surprisingly few articles answer the basic question: how should you actually teach a robot to do a task? Here's a practical breakdown of rule-based automation vs. Physical AI.

A step-by-step record of installing Isaac Lab directly into a pip/conda-based Isaac Sim 5.1.0 environment — without Docker or the Omniverse Launcher that most official guides assume.

Unlike Cosmos 2.x, which was nearly impossible to run on GeForce GPUs, Cosmos 3 Nano can be installed via diffusers. Here's a full record of setting it up on an RTX 5090 (32 GB) and the six errors I encountered along the way.

Attempted browser-based access via WebRTC, only to find it unsupported on Mac. A walkthrough of how I landed on combining Tailscale for VPN and NoMachine for remote desktop to securely operate Isaac Sim from a Mac anywhere.
