This week, I revised the physical part of the back system. I adjusted the battery pocket size to better fit the battery cord length and height. I also sewed the physical part of the feet sensor system together. At first, I designed a strap that fit both the leg and the bottom of the feet in order to accommodate the force sensor, the battery, and the Arduino nano chip. As I discussed this idea with my teammate, we found out that this idea might not be the easiest to use for users, so we changed the design to a strap that only has to wrap around the leg and have the users put the force sensor under their sole.
For the circuit part, I tested the circuit and collected the result, and organized them into a spread sheet. The table with results will be used in the final presentation.
My group mate and I also worked on the final presentation slides. Next week, I will focus on further testing and building the feet circuit.
