This project focuses on redesigning a compact, efficient, and robust differential swerve drive module for competitive VEX U robotics. Building upon lessons from last year’s prototype, the new module prioritizes smoother motion, enhanced gear clearance, and reduced strain on electronic components. The engineering process involved extensive CAD modeling using Fusion 360, integrating 3D printed components and CNC-machined polycarbonate for structural integrity. The final design achieves a 37% reduction in overall weight while improving gear contact and minimizing binding. By implementing a dual-motor system for drive and rotation, the swerve drive optimizes torque transfer and improves mechanical precision, crucial for maneuvering in high-stakes competition environments. Future efforts include real-world robot testing, encoder feedback integration, and FEA-driven optimizations. The project demonstrates a commitment to continuous improvement, manufacturability, and competitive performance, making it a strong candidate for real-world application in robotics competitions.
