Robotic Recycle Sorter


We built a robotic recycler. This machine uses color sensor and flips the trash to one side and the recycle material to other side.

Blue is recycle , Yellow is a Stop color and all other colors are trash.

We learnt a lot about the color sensor and switch statement.

    Wow! What a clever contraption–and you explained it beautifully. I love that you have a “stop” color that shuts down your machine.
