Idea - Lego Color Sorter

I spent parts quarantine sorting my lego collection and realized that there should be a better way to do it. I thought that this would be a good opportunity to make a machine to sort my collection. Similar machines have been made; in the link below there is a video about a machine that sorts legos by type and depostis the legos into bins.
Here is a link to that video


in that video he identfys 3 main problems in sorting legos atomaticly They are
- geting a single peace at a time from a pile(the fillter)
- identify the peace in the video he uses ai I dont know what i will do for this yet(the sort)
- puting the items in there designated bins(the place)

I agree that these are the tree big chalinges in aotomated lego sorting


My Plan

my plan I have is broke into three problem into three parts the sort, the pick, and the place. my plan is to work on the Sort first then the Place and lastly the Fillter.

  1. The Sort -this is the device that identifys the lego brick as a color
  2. The Place -This is the device that will take the identifyed part and place it in its corisponding bin
  3. The fillter -The is the mecinsm that will take one peace from the pile

The Rough Draft

This is the rough draft that I made in week one.

Fustion Modeling

Here is my design as of week two.

Applications and Implications Questions and Ansers

This leads to the Desgin questions that Neil asked us to anser during week 16

Applications and Implications Questions and Ansers

Budget as of 5 - 20

I ordered more parts then I will need to build the desine as of now. this is so if the design changes I wont have to order more parts.
