What does it do?¶

This machine can automatically sort various things by type.

Sorter¶

Move the identified things to the location of the target receptacle and deposits the item into the open receptacle.

Box¶

The Iris Mechanism opening of the receptacle opens automatically (triggered by ultrasonic sensor) as the sorter tray approaches.

Image Recognition System¶

Image recognition by Rasberry Pi camera and Teachable Machine.

By loading a model that identifies things, it is possible to recognize them by type.

Who’s done what beforehand?¶

Recycle AI self-made recycling robot

A self-made sorting system that artificial intelligence automatically performs separation of such troublesome waste

Three boxes are lining up, which is different from the separation of garbage in Japan, but from the left”Recycling garbage” “Landfill waste” “Compost garbage”It is said that it is a sort of separation.

Image recognition and stepping motors are controlled using Raspbery pi3

they had training their deep learning algorithms. The sorts of things they’re solving for are particular objects like polyethylene terephthalate (PET) bottles along with other thermoset plastics that can be recycled. The bottles can either be full of air or crinkled, and also partially obscured by other bits of rubbish. The algorithm is able to handle all these cases in almost real-time with a very high degree of accuracy thanks to the powers of deep learning:

What questions were answered?¶

In performing a series of flows, does the machine ensure idempotency?

Ran the machine multiple times with the same results. (For example, trash that can be turned into charcoal is always taken to the charcoal-able box.)

How was it evaluated?¶

Check to see if the image recognition system allows the sorting machine to move and dump the things into the target Box.

The series of flows worked well.
Check to see Whether the machine is able to classify more than 3 types of things

Three types of things could be recognized. Trash separation and color-coding of plastic bottle caps.

What are the implications?¶

This project was initially started to solve a problem in Kuriyama-cho, which is that it is difficult for humans to separate garbage. This is because the garbage separation rules in Kuriyama-cho are very strict. As the project progressed, I found that in addition to garbage sorting, I could also color-code the plastic bottle caps used in the Precious Plastic Machine.

I would like to simplify the identification and sorting process in Kuriyama-cho with automatic sorting by AI.

License¶

I have decided to grant the following license

Because I want many people to be involved in this project, I have only granted the Attribution license

https://creativecommons.org/

I also need to grant a license for the Drag Chain I use to hide the wiring of the stepper motor in my project, so I am granting an equivalent license.
