We were inspired to create an idea like this when all of us came together to watch a documentary. Having visited pier 39 recently in San Francisco, we were having a little obsession with sea lions, so we decided to watch documentaries on marine life. We realized how important information about underwater conditions is, and how much effort is put in on a weekly basis to simply gather this information. People manually have to go under and observe information specific to locations, which can easily be replaced by technology.

What it does

CorBall is a coral research ball, which goes underwater and is held together with the support of a buoy. Since it is housed with sensors and a camera, it is able to generate a live stream of footage of coral underwater, and our unique machine learning algorithm, coupled with Raspberry Pi's detection capabilities, can identify the exact hex codes of the color of the coral. Over time, if there is a change in the color of the coral, scientists will be notified of this, and they can finally quantify it against time, and draw inferences.

How we built it

We built this by creating a web server using a Raspberry Pi and DHT22 sensor to graph the humidity and temperature in oceans over time. The data can be accessed over a web browser. We have also used image recognition methodology using Tensorflow Lite with help from the OpenCV library, coupled with our own machine learning algorithm, that allows scientists to see the change in color codes over time.

Challenges we ran into

It was incredibly tough for us to be able to come up with a successful model of this, given that we did not have much background. For this reason, we each split up to handle one aspect, with one of us doing the machine learning research, two of us experimenting with the hardware available, and one of us researching the feasibility of this technology and creating the demo.

Accomplishments that we're proud of

In the end, we are so excited to share that we were able to create fully functioning technology! We were able to create a demo prototype of this with materials available to us, and have done all the research to ensure this is easy to fit into the real world.

What we learned

We learned the importance of "if there is a will, there is a way" - we all had a passion to help scientists and researchers around the world with the information they need, so we put in the blood (figuratively), sweat (literally) and tears (literally) to make this happen. We are so excited to see what this does, and hope that it will help us combat climate change!

What's next for CorBall

We hope to pitch this to investors to get funding and mentorship so that we can actually see it in action in the real world, helping researchers around the world.
