This week I worked primarily on finalizing the current design of our device. I am a bit behind schedule, in that I did not finish my design planning early enough to place the part order last week. I don’t think this will pose too much of an issue, as the order will hopefully go out next Tuesday, and I can use that lead time to start writing some arduino code to interface with the controllers such that as soon as they arrive I will be able to start testing. The ECE course that helped me to develop this design is primarily 18-220 and 18-100, which gave me basic knowledge around using sensors and arduinos, supplemented by reading lots of tutorials about inertial measurement units on the internet.
Aside from working on the hardware components, I also assisted with making slides / graphics for the design presentation. Next week I hope to get the parts in, and hopefully start testing by the end of the week, but if they don’t arrive in time, I will refine the design for the foot pressure sensing unit. This is because at this time, I was focused primarily on getting the more critical back unit done(as this is somewhat a blocker for Jasmine’s work on back orientation detection until we know what data we will be able to collect).
Here’s a link to the sheet I used to plan parts. https://docs.google.com/spreadsheets/d/19h7SsfZl7L6Hj6JMvvSDONWY2HEp8ZFq5vFqzvN0bgU/edit?usp=sharing
