This LEGO ball machine was constructed using 10 motors and thousands of bricks. Its 14 balls move continually through the machine, taking approximately two minutes to complete a lap.
Two Mindstorms NXT bricks control the green lift, blue lift and ball counter. A combination of Power Functions and traditional 9V motors drive the remaining lifts. The machine is built entirely from LEGO -- even the balls are LEGO parts.
