California farmers have mastered unmanned tractors: they are cheaper, greener and more productive.

Instead of a driver, such a tractor has a remote operator who monitors and receives alerts in real time. The vehicle is equipped with a full range of cameras and sensors, so you can instantly determine exactly which crop the device is working with, as well as collect data on the state of the crop and soil. The tractor is also equipped with sensors to detect livestock, crops and workers: the machine will stop until there are no obstacles in its path.
