Going into next week, we will be working on the design report with the feedback we got from the presentation. Mainly, we will be refining our test plan and making sure all of our metrics align with the tests we are proposing.
The most significant risks right now come down to integration with all of the hardware we are using – the two antennas, the RasPi, and our WiFi card(s). We will order an ESP32 card as a back-up, which we know we can get working based on some of our reference papers.
We’re considering maybe using a different WiFi module for measuring ToF, depending on whether we can get a rough ToF estimation working on picoScenes – the free implementation only comes with rough time measurement, not the 320MHz fine-time measurement possible with WiFi. We would probably end up buying an ESP32 to use and only 1 antenna for measuring ToF, but we haven’t committed to making the change yet. This would increase our implementation time by around a week.
To date, we are mostly up to speed with deadlines, with Thomas falling slightly behind on the localization front due to changing requirements/system topologies. He has started working with a sample data set from Intel to prototype the localization system until we can get real data to work with, which should be able to make up for lost time. Ethan can now start working on scripting measurements now that Polite Wifi is working. Teaming is generally working fine, since most work in the beginning can be done individually and we are communicating via Slack. Once integration starts, we will be working more in teams.
