Raspberry Pi is at the coronary heart of this AI–powered, automatic sorting equipment that is capable of recognising and sorting any LEGO brick.

And its maker Daniel West thinks it to be the to start with of its kind in the environment!

Greatest ever

This mega-equipment was two many years in the generating and is a LEGO creation itself, created from more than 10,000 LEGO bricks.

Impression: Daniel West.

It can form any LEGO brick you place in its input bucket into a person of 18 output buckets, at the price of a person brick each and every two seconds.

Whilst Daniel was influenced by past LEGO sorters, his creation is a substantial phase up from them: it can recognise unquestionably each and every LEGO brick ever produced, even bricks it has hardly ever witnessed ahead of. As a result the ‘universal’ in the identify ‘common LEGO sorting machine’.

Program

The artificial intelligence algorithm powering the LEGO sorting is a convolutional neural network, the go-to for graphic classification.

What will make Daniel’s undertaking a ‘world first’ is that he qualified his classifier working with 3D product visuals of LEGO bricks, which is how the equipment can classify unquestionably any LEGO brick it’s faced with, even if it has hardly ever witnessed it in real existence ahead of.

Daniel has built a whole added video clip (higher than) conveying how the AI in this undertaking works. He shouts out all the open supply computer software he applied to operate the Raspberry Pi Camera Module and access 3D education visuals and so forth. at this place in the video clip.

LEGO brick separation

The vibration plate in motion, feeding single areas into the scanner

Daniel needed the input bucket to very carefully decide on out a single LEGO brick from the mass he chucks in at when.

This is obtained with a primary and secondary belt slowly pushing areas on to a vibration plate. The vibration plate utilizes a tremendous fast LEGO motor to shake the bricks all-around so they are not sitting on leading of every single other when they attain the scanner.

A Raspberry Pi Camera Module captures video clip of every single brick, which Raspberry Pi 3 Design B+ then procedures and wirelessly sends to a a lot more effective pc equipped to operate the neural network that classifies the areas.

The classification final decision is then sent back again to the sorting equipment so it can spit the brick, working with a collection of servo-managed gates, into the suitable output bucket.
