WORK ACCOMPLISHED:
This week I focused on researching components for the software and hardware components of our device. I mainly focused on the GPS aspect of our device, which involved figuring out how the sensor data would be read, parsed, and filtered. Then ultimately sent to a cloud server for data processing. I also did research on the cloud server we plan to use + databases for storage of data.
The decision making for parts was based around price, efficiency, and integration capabilities. We’re using the Blues Starter Kit which comes with an Arduino board, dual cellular and GPS antenna, and a modem for connecting to WiFi. Blues focuses on efficient power usage, which allows for continuous use, but the ability to have energy saving modes for the tracking device. We’re using their cloud service to receive information regarding the sensor data, and transferring that to our own server which will most likely be a ubuntu server with a python web-framework due to the simplicity.
Most my time was spent interconnecting this device with the other moving pieces that we have, which was shown in the solution approach diagram that we had for our presentation. Specifically the Raspberry PI as the main center piece. Making sure there is streamline communication between our Raspberry PI device and the Blues cloud server. Using the cellular data on the Blues device also allows us to communicate directly with the sensors on the vibrating wristband, to allow for wireless connection between the motors and the raspberry PI.
PROGRESS:
I’m currently on schedule with my tasks, this week was primarily research and finalizing material needed which was accomplished. We plan to have a finalized parts list by Monday (02/09).
NEXT WEEK’S DELIVERABLES:
For next week, the goal is to have put in the orders for the materials needed. As well as starting to build the software systems that we need in order to receive and parse the data. I also plan to start working with what we currently have in the lab, to see how pieces of the Arduino connect with software, as a baseline to start with before our pieces arrive.
