Introduction
Computer-aided design is a digital modeling method that serves as the blueprint for modern robotics projects, defining the shapes, tolerances, and mechanical interactions of each component. More than 70 percent of robotics teams in advanced manufacturing environments report that their workflow relies on CAD-driven fabrication because it shortens build cycles, improves accuracy, and reduces rework. Yet the impact is not limited to industrial facilities. Designers, hobbyists, and research labs now combine CAD software with CNC machining, waterjet cutting, laser cutting, and 3D printing to produce functional robot parts on demand. As digital fabrication becomes more accessible, ideas move from screen to prototype faster, and experimental robotics suddenly becomes practical. This article explores how CAD shapes early design decisions, how CNC and other fabrication tools interpret digital files, and how engineers choose the best method for each part in a robotics project.
