Abstract
The aim of this work is to present the development of a bio-inspired approach for a robotic tail using Macro Fiber Composites (MFC) as actuators. The use of this technology will allow achieving closer to the nature approach of the tail, aiming to mimic a bird tail behavior. The tail will change its shape, performing morphing, providing a new type of actuation methodology in flapping control systems. The work is intended as a first step for demonstrating the potential of these technologies for being applied in other parts of the aerials robotics systems. When compared with traditional actuation approaches, one key advantage that is given by the use of MFC is their ability to adapt to different flight conditions via geometric tailoring, imitating what birds do in nature. Theoretical explanations, design, and experimental validation of the developed concept using different methodologies will be presented in this paper.

Summary
The use of Unmanned Aerial Systems (UAS) has increased exponentially in the last decade, including filming, surveillance, transportation, and inspection. Several approaches have been developed over the years for visual inspection [1,2,3]. UAS have been used for tasks involving physical interactions, adding actuators, and different end-effectors for performing manipulation or contact inspection, as can be seen in papers like [4] or [5]. Entire books have even been published involving this matter [6]. Multirotor systems are used in most of the above applications. The flight endurance is small and the rotors can be dangerous for persons or valuable objects nearby
