Over the weekend, the team continued to work on different designs using pulley potentiometers, slide potentiometers, and flex/bend sensors. The team then met with Professor Klaesner on Monday morning to get his thoughts on the various designs that were worked on in parallel last week. From this discussion, two major ideas were generated: using a trough-like support structure to mount the potentiometer mechanism onto and ironing out the main outputs our client, Dr. Carter wants. We met with Dr. Carter Monday afternoon and we decided our core priority is to construct any design that we can (we had presented 2 at the meeting) and produce a singular working prototype by Friday. We had asked Dr. Carter if he prefers that we aim to (a) create a mechanical design and software specifically aimed to get accurate angular displacement data or (b) to create solution that collects relative movement data. Solution (a) we believe is better supported by the design where the potentiometer is fixed in the same plane as the joint. Meanwhile solution (b) we believe is better supported with a slide potentiometer design measuring tension in a string based on movement generated along the slide mechanism. This week, we worked to create any prototype that could work. We used a variety of materials over the course of the week (rubber straps from goggles, graduated tubes, 3 oz travel size bottles, velcro, and more) to produce a working support structure. We plan to meet up with Dr. Carter again on Friday.
