Team Status Report: 12/4

The past two weeks saw some fantastic development! Lucas etched and manufactured our weight tag pcb’s. MeeDm worked on the Hub’s data analysis scripts. Tarush built out the Web App UI. Throughout Thanksgiving break, the team continued to work diligently. Thanks to Tarush staying on campus, we were able to continue to conduct system tests remotely.

After coming back from break, the team wrapped up the final presentation slide deck, and Tarush presented it on Wednesday. Way to go Tarush!

To wrap up the week, the team continued work on system integration. Specifically, Lucas and MeeDm worked to fix some final issues with the Hub not being able to find characteristic values sent by the Tags, and MeeDm and Tarush implemented further Hub controls into the Web App. We also got a fancy new enclosure designed and built for our weight tags.

As we enter the final week, we’re quite happy with the project. Still, there’s a lot left to be done. Our goals are to implement RFID sensing as well as polish the full project pipeline.

Lucas’s Status Report: 12/4

The past two weeks saw major development milestones reached and passed. First and foremost, I finally got the Weight Tag pcb etched and populated!

 

The tag runs our firmware and is powered from a single CR2032 coin cell battery.

I went back home to New Jersey for Thanksgiving but brought along plenty to work on…it got a bit messy:

While on break, I primarily worked on the RFID firmware, the Weight Tag hardware (populating a second board), and conducting live tests for our final presentation slides.

After coming back from break, I helped wrap up the final report. Specifically, I wrote the Solution Approach (slide 2), Hardware (slide 3), Live Testing (slide 7), Results (slides 8 and 9), Design Trade-Offs (Slide 10), and Lessons Learned (Slide 11). I also helped on the Project Management (slide 12) and Public Demo (slide 6).

After our final presentation, I took some time to design the enclosure for our weight tag from scratch and printed it out (bottom piece is printed but currently locked in Roboclub :P):

 

The enclosure’s top features a lip to snuggly secure the food bowl and a skirt to push any water or kibble that falls out of the bowl away from the electronics housed underneath. The bottom plate has mounting holes for our custom weight tag offset from the base to add further protection against water damage.

To wrap up the week, I debugged and fixed some issues with the characteristic values from the tags not being seen by the RPI over BLE.

With the weight tag just about fully finished, my goals for next week are to wrap up RFID and prepare for the final demo. Time is tight, but at this point I am confident we’ll have a solid project to show off.

MeeDm’s Status Report for 12/4/2021

I’ve since finished analyzing the data to check if the values are dangerous or not. I’ve also used Tarush’s code and edited it so that if it is dangerous, we send an email to the user. I did a statistical analysis to determine if the eating event was out of the norm or not and then sent emails accordingly (out of 2 standard deviations from the mean).

I’ve also finished up the code for determining the food consumed. I had to work with numpy arrays, etc. to subtract consecutive values and deal with edge cases.

I’ve additionally finished up writing the refresh_botton function that Tarush will call when the user wants. I’m now figuring out the kinks of python goodness with importing and using multiple functions from a file.

I’m also meeting later today with Lucas to figure out the remaining kinks for reading data from tags.

I’m on schedule still, and want to finish up the refresh_button function and reading from the tags.

Tarush’s Status Report for 12/04/2021

This week started off with me spending a good amount of time in creating the final presentation for our project and then presenting it for the class and the professors.

I was also able to accomplish a lot of the goals I had set up for myself(which I spoke about in the final presentation as well) I have deployed the web app on the pi and the url on which it will be demod will be http://172.26.161.0:8000/

I also have pretty much wrapped up the UI for the web app and attached some pictures below for reference.

As mentioned in the presentation, we wanted to be able to allow the user to request the latest information from the tags through the web app and so I’ve been working with MeeDm on accomplishing that. MeeDm will be working with Lucas on getting the information from the tags and then converting them to a readable format after which my web app will then be showing them on the graph. I will be assisting with that as well in any way possible.
