Have there been any enhancements to AI-based Lego sorters? Like many people, I’ve got bins full of mixed sets of Legos. A world where you can recognize pieces from a set and divide them up would be amazing!

There are lots of people who have made a business out of lego sorting - you send them mixed lego in boxes, and they'll send you back (for a fee) sets of sorted lego.

  What I would really like is to group Legos back into their sets. Or to recognize the particular sets that are contained in the jumble. I was hoping more advances had been made in recent years.

  What does "sorted" mean in this context? What is in each set?

With practice and the right methods, its possible to sort lego for well under 1% of the retail selling price using humans alone.

But I enjoy sorting things myself! I mean it's quite telling I've spent more time sleeving, sorting and storing my MTG cards than I have playing the actual game, lol.

Not really a sorter, but https://brickit.app/ https://brickit.app/ was mentioned on HN a while back, and does AI-based lego identification. I haven’t tried it, but it says it can show you where the pieces you need for a specific set are in a photo, so theoretically it should be able to show you everything that belongs in a particular bin as well.

  I tried this once but the results were poor. I got only very simple objects, nothing with more than 20 bricks.

I spend literally 2 months sorting lego by type and color and then recreate about 50 lego sets. I still have about 30 to go. I tried brickit app. Doesnt work so good when you have a lot of lego. The sorting and search efficiency can be improved with some tricks. But it takes a lot of time. Fun nevertheless.

I can't believe nobody created a lego-sorting-l machine out of lego yet

dang that's a good one. i was going to ask about training a model to assemble based on this corpus of instructions. but i think the hard part is making a machine with the tactility of a human.

What I want is a machine with these specs: Input: lego bricks, assembly manual. Output: assembled model
