Safety was a major consideration during the development of the Greenbot, so the machine is equipped with a high-end safety system. If the Greenbot encounters an unknown obstacle in its path, it comes to an immediate stop. It then sends a text message to the user, reporting the stop. The Greenbot probably operates more safely than any professional driver who has to do two things at the same time. The precision of our controller is unprecedented, which is important if, for example, you want to spray fertiliser or pesticide.
