I vibe-CADed a hexapod walker entirely with claude/codex, learned the walking gait entirely in the 3d simulator, 3d printed the generated files, ordered the full BOM from amazon, assembled the thing. The fact that this is possible is amazing, but there's still some clear differences between the simulated world and reality πŸ˜€.

@l2k The way it just gives up like a real animal dying is top notch.

@l2k Only minor differences πŸ˜‚ Amazing how much personification happens when it's physical - that thing is clearly struggling, poor spider!!
