This week, I did a lot of research into the chip we are using for our project and how it works. I learned that it has multiple threads to be able to communicate with multiple devices at once. This will be necessary to take into account when developing the multilateration localization routine. I learned that the chip has a built-in accelerometer (though we decided not to use it). I also learned that the chip can be connected via both SPI or USB to a Raspberry Pi, of which we chose to use USB for our final tag device. In addition to this, I also found and ordered the appropriate accelerometer and Raspberry Pi board for the project. Finally, I wrote my part of the design document, which included explanations of some choices of parts, detailed testing methodology for the project, explanations of how the work was split up, how the mapping works, how the navigation system works, as well as many technical details about both the anchor and tag devices.
I am currently on track with my work as I am currently in the phase where I’m supposed to be setting up and configuring the chip in preparation for developing the localization capabilities.
Next week, I hope to get a working trilateration routine working with a single tag device and 3 anchor devices. From there, all we will need to do is add the ability for the tag to communicate with more anchors simultaneously. Then we can add the navigation routine on top of that.
