MechAI — Demo video

An end-to-end autonomous mechanical engineering workflow, focused on mobile workbench design for this hackathon. The app takes a customer’s needs and turns them into formal requirements, develops a design concept, generates a B-rep CAD model, performs structural analysis and design-for-manufacturing review, and sends the complete engineering package to a Chief Engineer agent for final approval. If the design passes review, the system generates a procurement-ready RFQ package. The workflow is interactive and iterative: customers can make changes throughout the process, and failed engineering reviews automatically trigger design revisions and re-analysis. Instead of coordinating a mechanical engineering team over days or weeks to produce a custom workbench, the goal is to demonstrate that an autonomous AI engineering team can take a hardware request from requirements to a reviewed, fabrication-ready design in under an hour.
