Have you ever heard of color sorting?
All we need for this project are uArm, suction cup, color sensor, and some color cubes. uArm will pick up a cube and place it on top of the color sensor, then drop the cube accordingly. Different color cubes (Red, Green, Yellow) will be placed on different locations.
Check the video here and see how it works:
