Lars is 8 and lives in Belgium. He designed and built a bird with Lego Boost bricks, that pecks iron beads with its beak and sorts them by colour. It's a small robot with 2 Lego motors, connected to the computer via Bluetooth. Lars recorded his voice to let the bird speak. It says the colours of the beads it sees (using the Lego colour and distance sensor). The programming of the bird was done in Scratch.
