  Aerial field robotics research represents the domain of study that aims to
equip unmanned aerial vehicles - and as it pertains to this chapter,
specifically Micro Aerial Vehicles (MAVs)- with the ability to operate in
real-life environments that present challenges to safe navigation. We present
the key elements of autonomy for MAVs that are resilient to collisions and
sensing degradation, while operating under constrained computational resources.
We overview aspects of the state of the art, outline bottlenecks to resilient
navigation autonomy, and overview the field-readiness of MAVs. We conclude with
notable contributions and discuss considerations for future research that are
essential for resilience in aerial robotics.
