Abstract: A robotic orchard spraying system having autonomous delivery vehicles (ADV), each autonomously delivering an amount of a premixed solution over a non-overlapping path verified by a forward-looking sensor, video, or both. Also, a mobile control center, configured to wirelessly inform the autonomous delivery vehicle of the path within the areas and to confirm that the autonomous delivery vehicle is following the path within the area. Additionally, a mapper vehicle generates the path within the area, the mapper vehicle being configured to communicate information about the path and the area to the command center. The mapper vehicle senses the path with a forward-looking LiDAR sensor, and senses the area with a GPS sensor. Moreover, a nurse truck has a reservoir of premixed solution for replenishing a tank of the ADV. ADVs and the control center communicate over a radio network, which may be a mesh network, a cellular network, or both.

Abstract: A safety bumper assembly for a vehicle shutting off a vehicle engine when the vehicle hits an obstacle, particularly an autonomous vehicle used for agricultural purposes. The assembly includes bumper shafts holding a bumper bar at a distance from a support structure of the vehicle and shuts off the vehicle engine in such fashion that the vehicle comes to a full stop before the bumper has reached its most inward position closer to the vehicle body. A vehicle equipped with the safety bumper assembly has vehicle frame integrating a support structure of the safety bumper assembly.
