Flying control of small-type helicopter by detecting its in-air natural features

Abstract

Control of a small type helicopter is an interesting research area in unmanned aerial vehicle development. This study aims to detect a more typical helicopter unequipped with markers as a means by which to resolve the various issues of the prior studies. Accordingly, we propose a method of detecting the helicopter location and pose through using an infrastructure camera to recognize its in-air natural features such as ellipse traced by the rotation of the helicopter's propellers. A single-rotor system helicopter was used as the controlled airframe in our experiments. Here, helicopter location is measured by detecting the main rotor ellipse center and pose is measured following relationship between the main rotor ellipse and the tail rotor ellipse. Following these detection results we confirmed the hovering control possibility of the helicopter through experiments. Crown

“…With the evolution of computers and related technologies, several studies have been conducted on robots that can perform tasks deemed too risky or difficult for humans. To that end, the focus has been on developing wheeled robots [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ], flying robots [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ], and snakelike robots [ 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. Many recent studies focus on developing not only robots that perform risky or difficult tasks for humans, but also production robots in workplaces that face labor shortages [ 27 , 28 , 29 , 30 ], cleaning robots to support housework to meet the demands of our busy lives [ 31 , 32 , 33 , 34 , 35 ], and robots to support the medical sector.…”
