David’s Status Report for 2/11/2023

On the first week, I helped out with the presentation slides and constructed the Gantt chart for the entire team. Along with creating the Gantt chart, I discussed the work times required for each section and assigned tasks to each of the members of our team.

Aside from the presentation, I also discussed the Bill of Materials with the other members of the team. Prior to this discussion, I suggested that we could use the Coral TPU USB accelerator as a cheaper alternative to a Jetson. In addition, I researched the requirements to use a Raspberry Pi 4 as a USB peripheral device and determined that we can use the USB-C port for data communication. The problem now is that we need to power the device while transferring data, so I added a data/power splitter to the BoM.

Gram’s Status Report for 02/11/23

At the start of the week, I worked with my other groupmates to prepare slides for the proposal presentation presented by Xuan. We refined our requirements based on feedback provided from our initial proposal submission.

I also refined our block diagram this week.

After discussion with my group, we decided to modify our original design. Instead of using a Jetson as the controller for the compute module, we decided to make use of a Raspberry Pi 4 with a Coral TPU accessory instead. This works better because of many reasons:

  • Raspberry Pi + Coral TPU is significantly cheaper than a Jetson
  • Raspberry Pi supports Wi-Fi out-of-the-box
  • Jetson doesn’t appear to support HID behavior

Later in the week, after finalizing our block diagram, I helped draft our Bill of Materials. After we finalized our list, I put in the orders on the Google Form.
