M&M Color Sorter Demo

I designed and built this project for one of my engineering courses this semester. This is just a quick demo that I threw together to demonstrate its function. There will hopefully be a longer video coming soon but in the meantime more information can be found below:

Very cool design, good job!

[@ZongyiYang]

Cool build! I'm wondering if the design can be improved in the following way: use 4 plates with holes in them that look like your top plate. Plate 1 functions like the one you have, plate 2 also functions like the one you have with the sensing hole. plate 3 is linked to plate 1 like what you have done with an offset, but it's just a simple hole plate again. Plate 4 is driven by the second motor. After sensing the color, plate 3 will rotate and collect the m&m, with plate 4 rotating in unison but not uncovering the hole. Both motors keep rotating until the correct compartment is reached, where plate 4 will rotate a bit more to release the M&M. This change allows it to be more easily expandable in case a new color is added and has the same number of motors.

Fantastic!

[@jimbarchuk]

Excellent. Needs speed. There are way too many unsorted M&Ms out there. They won't wait! You know what happens when they're not sorted....

Monk does not like the light flash when you release the sweet.

[@StephenSpivack]

Wow, another cool project - how did you sample the color from each piece of candy prior to sorting it?

[@kurtbaehr5346]

Infrared returns different values reflected off different colors so a small ir sensor or hsv filters with a small camera maybe?

[@vishwajeet.743]

Can you send me details can it’s work on commercial production

[@ranemin3m]

I'm in awe this project gives me faith in humanity one day, all of the world's m&m's will be saved from the messiness that is unsorted

[@kyleeames8229]

Wait... There aren't equal numbers of all colors!? I feel lied to.

[@serdaraytemiz9978]

All fairness he used an uncontrolled batch for the test. I guess we will get a new video testing to see the number of M&M in one pack.

[@ToPProjectsCompilation]

Hey, the project is amazing. If you wish to feature it (no money involved), then kindly contact us.

"i'm not OCD i promise" lol

[@robstorms]

This caused me to go out at 1AM and buy M&M's . Are you Satan?

[@grantofat6438]

Most useless machine ever.

[@wfemp_4730]

The utility of the machine is irrelevant. This was an engineering course project to (from the author's website) "implement sensing, actuation, and autonomous sequencing". But I am curious. Using what objective criteria did you rate the utility of all machines ever built?
