摘要：A new drone system embedded with multiple
distance sensors was developed in this paper. Recently, drone
has been considered as an appropriate device for inspecting
building or social infra structure because it shows high mobility
and quick approachability by moving through free space in the
air. In general, it uses GPS as a fundamental tool to obtain
position of itself in the air because it provides sufficient
performance required for autonomous flight. However, in most
inspection applications a drone should move or keep hovering
near walls or artificial structures. Then, during such inspection
tasks, GPS is useless because of no or multi-paths problem of
radio signals from satellites. Moreover, a drone is required to
move and perform task according to commands given from
tele-operation by a user who exists far from objective point.
Therefore, a special function to detect walls as well as prevent
collision is essential to the drone for inspection works. This
research proposes a method to use multiple tiny distance sensors
embedded in a drone for detecting walls near itself. Besides, a
drone system installed with four distance sensors was developed,
and the usability of the proposed method was confirmed through
experiments.
