Meet Sisyphus Mini: a beautiful robotic system that creates works of art in the sand using a magnet and a steel ball. It can play path files like a music player plays an mp3 file. It has a usable sand field diameter of 9″ to 12″. All models run on 12VDC.
The Mini EX comes with all the moving parts beautifully enclosed and LED lighting around the sand field. The Mini ES is a cheaper version that lets you see Sisbot’s movements.
