This arachnid looking creation is actually a musical genius. Well, genius for a homemade robot that is. Xilo is a machine made of Lego’s that can play the xylophone. Xilo strikes the metal tubes based on your movements.
To create this yourself you don’t necessarily need a xylophone, a wind chime would work just as well. Xilo uses a vision command system and a camera to watch your movements. Wherever you move, Xilo cheerfully follows with a musical chime. — Andrew Dobrow
