The rest of the adjustability pieces have been 3D printed. This week the heel cup shelf will be finalized and the 3D pieces as well as the antennas will be adjusted. Additionally, the verification processes for the randomized locations and force levels will be finalized. The randomization code has been altered in order to control the motor drivers. This will soon be tested on the hardware. 

3 of the blocks that will be used to adjust the location of the force applicators have been 3D printed. 

The frame was constructed this morning. Christina Banat, project team leader bolted 80/20’s to the aluminum frame.

This week we will be sending in the SolidWorks designs to be 3D printed. We will be working on the frame in the machine shop. We have ordered screw terminals and male headers that will be used with the Big Easy Drivers. The code for the randomization of testing sites, force levels, and time intervals is almost complete. We will be working this week to use the Arduino code that we currently have to control the motor drivers. Once this is complete, we will begin coding the algorithm for the output score.

This past weekend the Arduino code for randomization of force levels was tested using 5 LED’s; 4 LED’s representing each of the force levels and the 5th LED representing the sham application. 

We have successfully tested the Arduino code for the randomization of the testing sites using 3 LED’s representing the 3 testing sites.  Next, we will be testing the Arduino code for the randomization of force levels using 4 LED’s representing the 4 force levels.

IRB: We have completed the application for the Institutional Review Board (IRB) that we will be submitting this week in order to test the device on human subjects. The objectives of the test performed on the subjects are to test that the force applicators hit the foot and to determine if the monofilament applications are predictable by the subject. 

Project Progress: Almost all of the device’s parts are in. We now have the motor drivers, stepper motors, Arduino Mega, 7-segment display, jumper wires, monofilaments, rack and pinions, steel rods, and aluminum plate. This week we will be ordering screw terminals for the motor drivers, a push button for the user input, and a switch to turn on the device. We are also finishing the SolidWorks and will be sending the designs to the 3-D printer this week. The code for the randomization of the forces, locations, and time intervals has been completed in C++ and we are currently working on converting the code to be utilized in Arduino.

Our treasurer, Aren Moy, has made a GoFundMe for our project to raise money in order to purchase the remaining parts needed for the device such as monofilaments, 3-D printing, and additional construction materials. https://www.gofundme.com/plantarneuropathyTCNJ 

This week we will be continuing to work on the design of the frame of the device, SolidWorks, and finishing the code for the randomization of the time intervals, force levels, and testing sites.
