During the past week, our group had been trying to do research and find a mentor who will help us along the way. We are waiting to hear from Dr. Jan Grudziak, a pediatric orthopedic specialist at Children’s Hospital of Pittsburgh.
Information about a newly designed KAFO brace with a different mechanism will be updated under "Types of KAFO".
Tomorrow, we are heading to TechShop for our first vacuum forming class. Hopefully, the class will inform and inspire us to create a brace with the help of the vacuum forming machine.

To get feedback and critique from professionals, we presented our project at Techshop.
Ratchet?? Transmitter???
03/12-3/27 SPRING BREAK
To build the fourth iteration of our KAFO model, we obtained a 3D leg scan of a four-year-old girl who's not affected by the disease. This time instead of drawing a generic shape of the KAFO, we horizontally sliced the leg and used the "LOFT" feature to create the brace so that it is contoured to the leg scan. The results are promising -- the shape of the KAFO turn out to be a lot more organic than our last iteration and is also much thinner.

Today we presented our project at the Pittsburgh Regional Science and Engineering Fair and won two awards: a four-year scholarship at Harrisburg University and a Naval Science Award from the Office of Naval Research. At this point we have a functional prototype built upon Karen's leg scan, but we have yet to finish building the latest model based on our teacher's 4-year-old daughter's leg. The Arduino microcontroller now has an LED light which turns on when the pressure detected by the pressure sensor is beyond the threshold values (too high or too low). Our next step is to add straps to the brace and incorporate the pressure sensor into our design.

Today we finalized our plan for our project for the STEM Symposium on May 19th. Our goals are:
-have our teacher's daughter try on our KAFO and walk in it to get relevant data (i.e. pressure data)
-attempt printing with different materials and different densities
-show display of data (on computer or LCD screen or phone)
