Field robotics is an area that is impelled by an application-driven approach by its nature. In this paper, I first review certain actual application areas of field robotics. Then, I discuss the current status of the application of field robotics in three common technologies: (1) mapping and path planning; (2) self-localization, recognition, and decision-making; and (3) dynamics and control. I then conclude by presenting future perspectives.
