Three Ball Machines on a Turntable

I spent some time motorizing HEXBUG ball machines, also modifying the ball outputs to link modules together. Actually the most time spent was to improve reliability to get smooth operation… I am still not completely happy with the Pick and Drop machine that ejects a ball from time to time!
To facilitate video shooting, I also built a motorized turntable (based on Spider head parts). The ball machines speed alternates between full speed and 1/5 reduced speed for each turntable turn.


Beautiful video! Nice robot cooperation.
