Shoulder Motion Simulator Actuator Design
- Developed and evaluated five linear actuator concepts, including a magnetic linear actuator, using weighted decision matrices comparing force output, response time, manufacturability, and system constraints against targets of 140 N force and under 1 kg system mass.
- Produced detailed SolidWorks engineering drawings with tolerances, section views, and assemblies to support design validation and selection of a rack-and-pinion actuator, incorporating DFM/DFA principles to improve assembly efficiency.
Role & Contributions
I worked on the early concepts, including Concept 4, the magnetic linear actuator. We scored all five in a weighted decision matrix on force output, response time and manufacturability. Mine wasn't the one we chose. We went with rack-and-pinion, because it was the one we could actually make. I drew the final design with tolerances and section views, and worked on the validation plan.
Concepts and drawings
Kinetic Energy Measurement Device for Hailstones
- Designed and built a portable experimental system to measure hailstone kinetic energy prior to ground impact, integrating mass capture, velocity measurement, and energy calculation under a $100 budget constraint.
- Validated accuracy and durability through controlled testing, achieving velocity measurements within a 5.1% standard deviation, a 99% funneling success rate over 150 drops, and an average deployment time of 27 seconds.
Role & Contributions
I came up with the core concept and led the prototyping and fabrication. I built the hail collection system and the energy measurement apparatus, then assembled the full device and tested it.
