Dual Connected Bi-Copter with New Locomotion Feasibility That Can Fly at Arbitrary Tilt Angle

Abstract

In our research, we focus on the information collection in multi-field by aerial vehicle. We develop hardware mechanism generating more efficient lift power to achieve the ability to tilt with continuous and infinite rotation and keep arbitrary tile angle while flying. In this work, we propose a new mechanism for aerial robot including four propellers separated to two mutually connected bi-copter modules. We call this new aerial robot Bi²Copter. With the proposed mechanism, we are able to realize take-off, landing and flight under vertical orientation of body, leading to the feasibility of image capture with full 360° spherical coverage as well as exploration and measurement parallel to the target surface of which curvature changes continuously. This paper presents the motivation to this new aerial robot, the design of proposed mechanism and flight control accompanied with experiment results.
