Claude Opus 5.5 accurately designs robot arm from sketch, validated by CAD and physics sim

A user detailed their experience using Claude Opus 5.5 to design a robot arm from a napkin sketch, breaking the process into five distinct steps. Claude generated engineering drawings, calculations, and JSON data files for each stage, which were then used by Claude Code to create 3D models in SolidCraft and set up physics simulations in MuJoCo. The user found that Claude's predictions for hinge angles, part weights, and load tests were remarkably accurate, with only minor discrepancies. AI
