Design and development of flying mode foldable ARM quadcopter

Abstract

Quadcopters are generally used for surveillance in both indoor and newlineoutdoor applications. It is difficult for the quadcopter to navigate from newlineoutdoor to indoor due to the narrow space in the indoor application. Also newlineQuadcopters designed with foldable arms are being used for easy of newlinetransportation on the ground. This has paved the way for this research work. newlineThe aim of this research is to design and develop a Quadcopter with newlinefoldable arms not only for the ease of transportation but also mainly capable newlineof flying in both Fold and Unfold Mode at various fold angles. This motivated newlineto design a quadcopter with foldable arms where arms in fold mode provides newlinemore agility as generally quadcopters with smaller arm length have, whereas newlinearms in unfold mode provides more stability as generally quadcopters with newlinebigger arm length have, so that same vehicle can be used for both indoor and newlineoutdoor applications. The vehicle can be flown in fold mode in order to newlinenavigate through narrow passages in indoor navigation and in unfold mode newlinefor aerial photography effectively. Hence, this research approaches a smooth newlinetransition between Flying Mode Foldable Arm Quadcopter modes both on newlinethe ground as well as in flying conditions. It is achieved successfully through newlinethe retraction and extension of the arms of the Quadcopter in flying mode, newlineresulting a reduction in arm-to-arm distance. Further these agility and stability newlineaspects are verified with Ecalc analysis software. The simulation results newlineconfirm that improved stability in unfold mode and also improved agility in newlinefold mode. An increase of about 4.9-km/h speed is achieved in the folded newlinemode than in unfold mode. newline
