This is a concept model for a real structure that is powered by solar cells located on its roof. The solar cells power the automated lawn-mowing appendage whenever the sun is shinning. As the sun shines and makes the grass grow, the automated lawn-mowing appendage keeps the grass cut to a predetermined length as it rotates around the circular lawn from a center radius point.
