Ah, a lift mechanisim would probably solve all of your problems. They are used in forms of kinetic art called "Rolling Ball Scuptures". There are two basic kinds: there is a bicycle chain lift that has prongs that can carry a ball upwards, and there is (my favorite) a screw lift-basically a vertical screw that spins and lifts the ball up to the top. There are other types of lifts-just search for "Rolling Ball Sculpture" and you'll find lifts as well as other elements you might want to look at. Try www.eddismind.com first.

A conveyor belt type elevator might be the easiest. There would be no controller necessary, it just runs. A scoop on the belt will pick up a marble, take it to the top, drop it off, scoop goes back down and around to get another marble.

Good call....I have taken some rolled roofing ...hooked up a motor and belt and pulley and it seems to work....I found out that with the rubber roofing material that all I have to do is staple the belt together to get the right tension and to make the buckets I stapled them too. Son of a gun if it didn't work! Thank You for the concept.
