During the spraying operation, it is important to consider environmental conditions, particularly wind velocity. Droplets carried by out of spray zone may be onto nearby plants, soil, water bodies, residential areas, etc. Various measures have been developed and used reduce droplet drift address this problem. Robotic systems, such as unmanned aerial vehicles robots, are now increasingly being used. The influence lateral winds on processes these systems has not yet extensively investigated.
