Modelling, Analysis and Control of OmniMorph:an Omnidirectional Morphing Multi-rotor UAV

Abstract

We present the design, modelling, and control of a novel morphing multi-rotor Unmanned Aerial Vehicle (UAV) that we call the OmniMorph. The morphing ability allows the platform to switch between different configurations to achieve the required task. The uni-directional thrust (UDT) configuration can be used for energy-efficient navigation, while fully-actuated (FA) and omnidirectional (OD) configurations can be used for full pose tracking and make the platform assume any orientation while compensating the gravity. The platform is equipped with eight bi-directional propellers that are actively tilted in a synchronized fashion using only one additional degree of actuation
