Feasibility Study of a Novel Cross Assembled Multi-quadrotor Unmanned Aerial Vehicle

Abstract

In this paper, a feasibility study for construc- tion and control of a novel design of a Multi-quadrotor unmanned aerial vehicle (UAV) is presented. This novel concept tests four identical Quadrotors assembled in a bigger cross structure. And, it also tests the ability of using the same controller that is used to control a single quadrotor to fly the novel design of cross assembled four quadrotor UAV. The main objective here is to improve redundancy and robustness and load carrying capacity of quadrotor UAVs. Even though there are four quadrotors, there is only one controller involves. When each individual Quadrotor works on a certain flight maneuver, it is expected that the assembled UAV of four of these in a cross structure to also be able to demonstrate the same maneuver. The prototype of the novel UAV was designed and built, and has been experimentally tested for a proof of concept where it was able to stabilize the new UAV with the same controller that is used in typical quadrotors with minimal modifications. New UAV will provide the user with the ability to lift more weight while also allowing plug-and-play replacement of individual Quadrotors in the assembly.
