ReMaterials, a roofing company in India, needed an impact tester for their roofing tiles. I built and designed one.
ReMaterials, a company based in Hyderabad, India, manufactures low-cost roofing tiles. Like any building materials, these tiles, which are constructed of reclaimed cardboard, must undergo life-cycle testing before installation. At the Rematerials plant, this meant hiring a man to climb a stack of boxes and jump from a fixed height hundreds of times. My fellow Tufts senior mechanical engineers and I knew we could come up with a more efficient and practical solution.
Over the course of three months and regular Skype sessions with the founder of ReMaterials, we developed and built the "ModRooster," a cyclic fatigue tester that raises and drops a 180lb load from a height of one meter, accurately reflecting the real world stresses that ReMaterials' roofing tiles undergo. My role in this project? I helped kickstart product development, brainstorming mechanisms to best apply our loading, and then took charge of all electronics and software design, building a Raspberry Pi-powered platform to run the entire system.
The Tufts team and I flew to India to present and install the ModRooster in January of 2018. While customs hiccups have temporarily prevented full machine installation, I am proud to report that the electronics and software are all functioning as intended and are safely deployed at the ReMaterials workshop in Ahmedabad.
