The UAVs that are linked wirelessly are subject to cyber-physical or harmful assaults
to fool the control signals due to open communication lines. Such attempts represent a
significant risk to the unmanned aerial vehicle system in terms of private information
crash or theft, as well as mission failure. Moreover, the faking of control signals may harm
the UAV mission and make it harder to restore it. As a result, improving UAV wireless
communication’s safety and confidentiality element, which necessitates in-depth research
of security concerns covering the entire network protocol layers [

], is an important
open subject.
Visual harvesting of robots’ dynamic tracking of objects with great precision remains
an unresolved challenge. Further study should also aim to enhance the precision placement
and operation by merging smart behavior judgment, adequate fault tolerance, robot vision
with artificial intelligence technology for accurate placement, and function enhancement.
The recognition and location accuracy are impacted when the crop situation is varied due
to the lighting and unconstrained circumstances of the field ecosystem. A robot vision
approach would be efficient in harvesting crops correctly to increase the success rate of
robotic harvesting in such settings. The researchers used geometric features, novel image
algorithms, and intelligent decision theory to address the challenges. However, because
massive datasets are necessary to train efficient deep learning algorithms, further study
is needed [

]. Table

agriculture obstacles and benefits.
