Problem
Design a VEX U Spin Up robot capable of fast intake, accurate shooting, and effective defense under strict time and mechanical constraints. Winning required high-speed cycling and dependable autonomous scoring early in matches.
What I Owned
Mechanical design ownership for intake + dual-flywheel shooter architecture
CAD modeling and iteration planning (SolidWorks, Onshape)
Subsystem integration across drivetrain, intake, shooter, and controls interfaces
Test plans, stress checks, and performance benchmarking to match conditions
Approach
Mechanical Design
Prototyped multiple intake and dual-flywheel shooter layouts
Prioritized lightweight structure, stiffness, and maintainability for fast cycle times
Systems Integration
Led fit, mounting, and packaging decisions across drivetrain, intake, and shooter
Coordinated wiring and control compatibility with the electrical/programming team
Autonomous Enablement
Collaborated with programmers to support odometry-based navigation and PID control
Tuned mechanical alignment and repeatability to improve autonomous consistency
Testing and Iteration
Benchmarked shot consistency, cycle time, and durability
Iterated quickly using measured results to converge before qualifiers
Outcome
Qualified for VEX U World Championships
Delivered a dual-flywheel shooter with consistent accuracy and high throughput
Reduced autonomous cycle time by 30+ percent via PID tuning + mechanical alignment
Strengthened real-world systems engineering skills: design tradeoffs, integration, and rapid debugging
