Coin Sorter
Coin Sorter
This sorts pennies from other coins and pushes them different ways

It takes input from the color sensor to decide if the coin is a penny. It then uses a servo with an attachment I made to push the coin either left or right for the respective color. In the future, I plan to then have it sort the silver coins by size.
I think it is cool how you got the camera to be able to detect what type of coin this is.
Hi Isaac! Cool robot, I especially love the little loop you’re using to grab and throw the coins
Love the idea. Really useful especially if dealing with lots of change. Great use of the color sensor!
I think the idea is really cool. It’s really useful to sort different coins. Maybe in the future, sort more coins like quarters and dimes?
I am definitely going to try. That was my original idea, but I couldn’t get the camera to work right in time sorting by size.
Cool idea. I was very impressed with how fast the robot was able to identify if the coin was a penny or not.
I think the motor does a good job sorting the coins and the idea is great.

I like the execution a coin sorter, I think having a way to catch coins as they are sorted would make it even better
Agreed! Not having to pick them up from the floor would have made it much more useful
I love the use of the aggressive servo to sort the coins quickly. Did you use ML to learn what color is a penny or just hard code it? I can’t wait to see the next revision with size sorting.
I think this is a super useful idea that could definitely help someone get change or even count their money. Do you think you will maybe implement some sort of dispenser so multiple coins could be sorted as once. That addition would be super helpful because placing the individual coins in the tray kind of defeats the purpose of an automatic sorter, but otherwise, this was done super well!!
Does this work with those really gross/old pennies?
It doesn’t work with pennies that are more black than copper, but duller ones work best because the color sensor can see what color they are better. The super shiny ones sometimes act too much like mirrors and makes the robot think they are silver.
Amazing idea Isaac! This definitely has so many useful applications from sorting to counting change. I can’t wait to see the end product you have in mind!
I love this idea! Do you plan to keep working/improving on it in the future?
