This project focused on developing an adjustable tabletop catapult, progressing from early concepts to a fully integrated design through modelling, fabrication, and testing in a five-member team. The design features a ratchet-and-pawl cranking mechanism attached to a fishing line to control launch force, and a belt-driven carriage system that can slide to control launch point.

I led the group through multiple stages, including SolidWorks CAD, the production of the belt-driven carriage system, and the development of a formal engineering report. The 23-page engineering report documented the project from concept to final product, including sections on specifications, problem definitions, testing results, and final performance analysis. The belt-driven carriage system, developed under my guidance, resulted in a final design that doubled the system’s original launch distance, while proving to be much more consistent.

The catapult was built collaboratively using a combination of machining, laser cutting, and 3D printing (FDM & SLA).
