Sentry

Inspiration

Anduril and other defense autonomous systems

What it does

Uses object detection to detect person and move across 2 degrees of freedom to "track"

How we built it

Using odds and ends we had as well as 3d printing a base to use, and a Pi 5 16GB as the compute

Challenges we ran into

Many, from physical design to driving the motors, to our algorithm for tracking, and many many more

Accomplishments that we're proud of

The optimizations we had to make in order to get everything synced up, and surpassing what our compute itself could accomplish

What we learned

So much about real world implementation, physical design, CAD for 3d printing, and many things about driving motors, syncing them, and using threads in python to use as many resources as possible, trying to get around the GIL

What's next for Sentry

It is very extensible it is cheap, a 2 degree of freedom physical design, and the compute has much room to grow.
