Who is the “Little Prince”?
“Little Prince” is a robot gardener, namesake of the book by Saint Exupery. It was made to find on Mars the necessary elements for plants to live in the planet. It has to learn how to find nutrients for the plant it carries in its body.
When it is in the right place, the robot stops to absorb the nutrients, and the sprout grows. This learning is transmitted to its friends robots gardeners, making easy the exchange of learning among them.
