S56 - 2 Bin Detection System

S56 Prototype Goal

The goal of S56 is the same as S57's, which is to separate trash from recyclable material.

This model is the most recent prototype and consists of Acrylic, HDPE, and 3-D printed parts. The ideal process for this design is to have two bins, one for recycling plastics, and the other for recycling metals. The ideal result would be for each lid to open with respect to their corresponding components. For the lids to open accordingly, both bins use an ultrasonic sensor and a capacitance sensor. This will determine whether an object is in front of the lid and whether the lid should open or not.

My Contribution

For this prototype, I designed the preliminary CAD model and the manufacturing model, and manufactured and assembled what has currently been fabricated.

This model is made to be placed on any type of bin, with only minimal changes to the design interior design.

This is the full CAD of the manufacturing model

CAD Demo

This shows what the movement of the trash will be when the right material is detected.

Current Progress

We currently have about 95% of the first bin completed. The sensors were already tested and respond to any metal and currently we have

These are pictures of the connecting piece between the lid and the servo motor, the shaft, and the interior for the first bin.

This is is the connector that allows the servo-motor to move the bottom lid up and down. It has a piece specifically created for the motor inside the left portion where the hole is.

This is a general photo of what the interior would look like. It contains the shaft (black), the top lid (beige), and the component mount (clear), as well as some of the electrical components.

This is a photo of the water jet cut bottom lid (white), as well as the shaft (black) and the mount spacer (black) which is at the bottom of the mount.

Next Steps

All that is left is to create a second bin with the same exact components as the first and to laser cut the component holder, so that the servo-motor will fit with the mount.
