3D SCANNER: This is a 3d scanner: you place an object below the axle (here you can see a Roman Colisseum mini figure) and start scanning. The axis goes up and down registering the depth of every point by using a rotation sensor. When it finishes a scan line, it rolls a bit and makes another, gathering "every" point´s coordinate. The visual basic program creates a matrix with these coordinates, and makes a 3d graph, allowing you to rotate the object.
With this robot I´ve won the february-march expert contest at Lego Mindstorms (R) web site!
