DIY AI Solar Weeder - Part 6 Custom Image Classifier (new tflite model for Raspberry Pi)

This is a video series that builds, wires, tests and operates version 2 of an AI powered solar weeder. All files can be found at:

This video shows how to retrain an image classification model for use on a Raspberry PI. There are 3 steps:
1. Obtain photos - these must be as similar to what you'll classify as possible. We take photos with the robot and divide them into 224x224 size
2. Classify Photos - this is done by hand, but we automate it as much as possible so we can get a few hundred examples of each image class in a few hours
3. Retrain an existing model using Google Media Pipe Model Maker and then quantize it so we get a model_int8.tflite model that will run quickly on Raspberry Pi.

My goal is cleaner, cheaper food for everyone. Small AI powered robots like this one can remove weeds without use of chemicals and save farmers the time associated with weeding. My goal with this series is to show how to build and operate this robot so that anyone can pick it up and use it or improve on it, eventually reaching the goal of an improved robot that delivers cleaner, cheaper food for all.
This robot is controlled via a web interface. I'll show how to add to the image classification model to address weeds in your yard and I hope you'll share your training sets so that the model can continually improve and address more and more common weeds.

Nice project. thank you mr.

This has been an excellent series Nathan. You've covered all the basics for an ag robot weeder, whether we use a different route or not. Thanks for all your efforts.
I can see how a compact robot to fit between the rows would be a different approach than current agtechs are taking with elevated robots.
Also, I wonder how off the shelf lasers might be simpler and efficient (although $$$) in real small farm use.
Your building blocks will be very helpful to make this happen.

I really like this. I would be concerned about scaling this because of potential fires. I wonder if a similar approach of using the solar energy to heat water in a tank then administering the water to the weed wouldn't be safer?

Would you be wiling to share your training images?
