determine a target location corresponding to the
medical situation, (c) select a UAV from the fleet of
UAVs, where the selection of the UAV is based on
a determination that the selected UAV is
configured for the identified medical situation, and
(d) cause the selected UAV to travel to the target
location to provide medical support.
