This week, we have updated our tentative Pugh chart to include combinations of all possible ways to measure force, range of motion, and velocity. The combination with the best score will be the combination that is chosen to begin development during the next week. Note that we explored many options for measuring the three major components (velocity, force, and range of motion), and these are the three groupings that were most logical. For example, it would not be logical to use the accelerometer for velocity and not for range of motion, since the accelerometer can do both.

Additionally, we have made contact with Dr. Thoroughmanâs lab regarding borrowing a force transducer, and they are currently looking for a spare force transducer to aid us in our project. Buying a force transducer would cost about $100, and may be out of our groupâs budget, so we are trying our best to find one from a lab.
Work Planned for Next Week:
We will begin work on figuring out how to develop an Android app and begin building the interface, as well as range of motion and velocity components. Additionally, we will go further with Dr. Thoroughman to hopefully use the transducer this week.
Anything needed from Client or TA before work can progress:
Could one of you (or both of you) comment on our Pugh chart so that we have an idea of how on track we are. Do we have enough options listed? Thanks!
