Jeff’s Status Report for 02/10/2024

This week I researched the various technologies that are typically used in indoor localization. I compared using Wi-Fi, Bluetooth, and UWB, finding that typically UWB has the highest accuracy, most resistance to interference, as well as having decent range, with the cons being that the devices are newer, hence the device prices are relatively higher. Next, I looked into which UWB devices would be a good fit with our project. The Qorvo DW1000 chip seems like the best UWB transceiver option, and there are a few developer boards that incorporate it, such as the ESP32 UWB.

A summary: Design Review_ What is the best indoor localization technology_

My progress is in line with our Gantt chart.

Next week I will be working on the Design presentation, as well as continuing to do research and discussing further with the team of how the project will end up unfolding. I would like to start working on the Django website by setting it up.

Weelie’s Status Report for 02/10/2024

On the proposal, we got a lot of suggestions for our projects. For indoor positioning and navigation, there are a lot of possible solutions and combination of devices. To figure out what combinations fit us most, I researched on the algorithms that can achieve our goal. I mainly read through algorithm papers to prepare for our final decision. I will attach the interesting ones for us.

Based on the gantt chart, this week is on schedule for me. Since we havn’t get our devices yet, I couldn’t do more than rearch on the algorithms.

Now we have decided to use ESP32_UWB or Computer Vision approach for our projects. For the next week, after we bought all the widgets, I will work on set up these things. If we couldn’t get these devices, I will work on doing more research on UWB and CV indoor navigation.

Introduction and Project Summary

Have you ever gotten lost trying to find a classroom in a building at CMU? Rhetorical questions aside, we wish to create an application and device to aid students in easily finding their classes. Our goal is for our device to use indoor localization to accurately provide the location of the student’s location from within a building. We wish to create a portable, lightweight device the student can easily carry around. Furthermore, we will create a responsive webapp user interface that displays instructions of the best path the student should take to their desired location. Ultimately, we would like Scotty Maps to be a tool for students to save time and learn how to navigate the buildings on campus.
