How can football save crops?

Rosper is a robot that looks like a football. However, it can be a perfect tool in the fight against drought.

Due to increasingly obvious climate changes, field crops fail more and more often. In order to solve the problem of irrigation and beat long-lasting droughts, Spanish scientists have invented Rosper.

This robot detects which part of the field needs to be watered, that is, which part requires more water and which one should be less watered. Besides, it also sends out information on parasites.

The price of this robot is quite affordable, so it is assumed that Rosper will have a wide application in agriculture.
