Location Holding System of Quad Rotor Unmanned Aerial Vehicle (UAV) using Laser Guide Beam

摘要

Recently, unmanned aerial vehicle (UAV) has been developed in industrial applications. UAV usually has fixed-wing aircraft and rotor-type aircraft. The rotor-type aircraft is divided by single-rotor type and multi-rotor type. Quad-rotor aircraft (QRA) is flying using rotor with two pairs of symmetrical to each other. In this study, we chose to quad-rotor aircraft, because it is able to do vertically take-off and landing and hovering function. UAV are used at hard-to-reach areas for human, such as transmission tower or high-rise buildings. In the vicinity region of these buildings, radio disturbance by high-voltage power lines tends to occur in. Generally, GPS is used in order to detect the UAV position. Hence GPS cannot detect UAV position in the radio disturbance areas. In this paper, we show location holding system of UAV using laser guide beam. That system enables a multi rotor helicopter to hover in the radio disturbance areas distributed around high-rise buildings. This system consists of a photo-transistor array position sensor mounted on in the UAV and laser guide beam on the ground.
