The "WatArrow RC Plane" project focused on redesigning an RC aircraft for the SAE Aero Design Competition. Design goals included reduced takeoff distance, weight optimization, durability, and ease of manufacturing. By researching aerodynamics and competition criteria, a lightweight carbon fiber rod replaced the traditional fuselage, achieving a 70% weight reduction. Custom adapters were developed for wing attachment, resolving mounting challenges without compromising strength. The final prototype demonstrated improved performance, with a takeoff distance under 7 meters and speeds of 15 m/s
The "Launch Tower Base" project involved redesigning a rocket launch base for the UWaterloo Rocketry Design Team. Key goals included lightweight construction, portability, cost-effectiveness, and elevation off the ground. Using SolidWorks and Ansys Mechanical, the design incorporated a Howe's Truss for strength, adjustable base legs, and an innovative hinge mechanism for transport and setup. The final design supports over 8000N of force with minimal deformation and a safety factor of 3. Manufacturing is set for completion by April 2025.
The "Maze Runner" project involved designing an EV3 robot to autonomously navigate mazes, retrieve blocks, and sort them by color. Using a left-hand-turn algorithm, 2D array mapping, and sensor-based navigation, the robot achieves high accuracy. A custom 3D-printed gripper efficiently picks up and places blocks, addressing challenges like weight balance and friction. The maze pieces were laser-cut, optimizing cost and usability. The final system met all design goals with a block pickup success rate of over 90%.
The "Armageddon" project was a pressurized gas launcher designed as a forearm-mounted toy for children aged 10–13. It launched projectiles using air pressure from a bike pump, achieving impressive distances of up to 98 feet. Key features included an ABS piping structure, adjustable Velcro straps, and two types of projectiles: rockets and planes. Through iterative design, the system incorporated an improved solenoid valve for optimized performance. This rewarding first-year engineering project combined creative problem-solving and hands-on learning.
