Week TechVideo, 2012 #04 - Sorting Plant

Kenneth & Lasse that you may remember from the "C5 - The Flying NXT Blimp" project, returned with a massive creation!
They have now created a sorting plant, that sorts 2x4 and 1x2 bicks in size and color. This is a model commissioned by Dynaway and it is used to demonstrate their manufacturing execution system. The model was designed to fit inside a large flight case, so that it can be easily transported among demonstration events.

The bricks get sorted directly into pallets in a high bay storage system. When a new color is detected, an empty pallet in the high bay storage is assigned to the color. When a pallet is full, a robot retrieves it, and returns a new empty pallet.

There are 7 NXTs in the plant and they all communicate with each other and a PC application over Bluetooth. The software was written in leJOS, which is a java language for LEGO MINDSTORMS.

Together with these, there are many more NXT motors and sensors. You should visit the BrickIt team's website, for more details.

Pretty fast sorter there!

It's impressive and, as far as my limited knowledge of the area goes, realistic, but, in terms of ingenuity, I admire much more the single-motor-no-NXT sorter presented on TBs earlier.

I'm quite sure the image on the right is from a model build with SR 3D Builder (I can recognize my software images), so, please, can anyone report this information also?

Hi Sergio!

Love your software!!!
The images are made with LD-View. But we've used your software to design sub-models, and then gathered everything in ML-Cad before rendering with LD-View.
If you have further questions, don't hesitate to send us a mail on
