I've gotta find plans for this "Cup and Balls Robot".
It would be so cool, if it was made out of Brass, Aluminum, Stainless, Copper, Bronze, Steel, Etc.

How the heck does that work? Iím thinking there has got to be 2 or 3 balls and some deal to hold them in the cup. I want one just to rip into it and figure out what the heck makes it tick . . . my Mom always complained that even as a little kid I only wanted toys so I could take them apart. ;)



EDIT: Oh . . . I think I have it! Little magnet in each cup and a strong magnet under the table indexing to one ball at a time.

Think that's right, if you watch closely, you can see an arm or two do a sideways 'jerk' that would correspond to the under table magnet moving away from, or towards it
