I think it’s always good to dig a bit deeper on these things.

This seems ridiculous to you, compared to a very obvious win with a Lego sorting vacuum.

Lego isn’t niche, and the explanation isn’t a weird technical thing that only experts would get and understand how important or valuable it is.

Yet it’s not being done.

Is there nobody who has realised this gap but you? Has nobody managed to convince people with money that it’s worthwhile? Have you tried but failed?

Or is it not many many thousands of people who are wrong but you?

Is the problem harder than you think? I’ve worked with robotics but not for a long time and I think the core manipulation is either not really solved or not until recently. I don’t know about yours but my kids also don’t fully dismantle their Lego creations either so would the robot need to take them apart too? That’s a lot of force. And some are special.

How people want Lego sorted is pretty broad. Kids don’t even need it sorted that much. And the volume can be huge for smaller buckets of things.

Is the market not as big as you think? Is it big enough for the cost, I’d buy one for £100 but £1000? £10,000?

How does it compare for most people against having the kids play on a blanket and then tipping it into a bucket? Or those ones that are a circle of cloth with a drawstring so it’s a play area and storage all in one? I 3d printed some sieves and that’s most of the issue right there done.

People are solving actual problems, but lots of problems are hard, and not all of them are profitable.

As a gut feeling, there is such a large overlap of engineers and large Lego collections and willingness to spend lots of money and time saving some time sorting Lego that the small number of implementations usually split over many years is very telling about the difficulty.

For what it’s worth I want this too.
