7Swaize/go2-control ? reverse-engineered prompt

Build me a Python SDK for controlling a Unitree Go2 robot and its MuJoCo simulator through small attachable modules.

I want it to feel easy to use from simple example scripts, with separate examples for movement, video, OCR, ArUco marker detection, and terrain generation. Please include clear setup instructions for Ubuntu 22.04, and make sure the simulator can be launched separately before running example code. The main goal is to let someone copy an example, tweak it, and start sending commands to the virtual robot right away.

Also add clean documentation pages for installation, a quick start guide, an FAQ, and a basic API reference. If you need to check current MuJoCo or Python setup details online, go ahead and do that. Keep the project organized so it can work as both a simulator focused SDK and a foundation for robot control later on.
