There are four simple steps when using Aros:
My Role - I played a large role in identifying the user scenario, market research, and competition analysis. I did the engineering for the measurement and dispensing mechanism and conducted force analyses on all mechanical components. I also
created build plans for injection mold mass manufacturing and aided in the fabrication of the proof-of-concept.
Fall 2014. The Aros proof-of-concept was fabricated from 3-D printed ABS plastic and NinjaFlex, laser cut clear acrylic, steel pins, a spring, and magnets.
