Current Status of Project:
We have now purchased Arduino Duemilanove ($19.99), ADXL335 accelerometer ($14.95), and Bluetooth Module RS232 ($6.65). The Arduino and accelerometer have been assembled and can connect to the computer. The program reads the x, y, and z axis proper acceleration and convert this to an angle measure depending on its orientation in the xy plane. We have attempted to store data on the Arduino so that all of the calculations can be done. However, we ran into some problems with memory allocation, but there may be workarounds. We have also obtained one option for our choice of FSR (Interlink Electronics FSR 406), and will obtain another one from Dr. Klaesner on Monday. Our physical design will change to accommodate this larger-sized FSR, approximately 4cm x 4cm.
Work Planned for Next Week:
We will attempt to successfully store data on the arduino module, allowing programming of the velocity acquisition to occur. In tandem, the FSR will be assimilated into our circuit. Once this occurs, we will program the algorithm to include all three quantities to output a single spasticity value for the first time. We also hope to print/assemble the final patient strap design.
Anything needed from Client or TA before work can progress:
We are hoping to discuss the final product design with the client this week before moving forward and finishing assembly.
