One prompt into Codex: agent self-calibrates and sorts Lego blocks in MuJoCo robot sim

Developer mishig25 shows a prompt you can paste straight into Codex to set up and run an SO-101 robot simulation: the agent reads the README, downloads files, uses uv for all Python environment and package management, then runs camera calibration and a block-sorting demo.

No VLA involved — GPT-6 Astra calibrates itself and solves the task of putting Lego blocks into a box. The whole thing runs in MuJoCo simulation, so anyone can try it without owning a physical SO-100.
