A bit of sun... and the ecorobotix does stop the weed from growing in your crop, by it's solar panel powered autonomous manoeuvring. For weed removal, herbice will be sprayed only on the location of the unwished plant. The machine is from Swiss. 
 
Becoming a mature field robot
Ecorobotix has experimented a lot and continued development towards this EVO model. In 2021 this field robot will be limited available, in order to continue more mature into next series. Next to the robot, Ecorobotix is also offering spot-spraying as a solution as a tractor attachement.
