2e conference AETOS "RESEARCH CHALLENGES FOR FUTURE RPAS/UAV SYSTEMS" - 9 & 10 septembre 2014

En parallèle du salon, se tiendra la 2e conférence internationale AETOS, avec la participation d’intervenants internationaux (Europe, Etats-Unis, Nouvelle Zélande…). Parmi les thématiques traitées cette année : l’optimisation de modèles mathématiques dans les domaines tels que le vol en formation, les essaims, l’autonomie des systèmes, l’insertion dans le trafic aérien, la résilience, la sécurité, ou encore les systèmes hybrides.

Qu’il s’agisse ou non d’UAS (la notion englobant à la fois RPAS et Systèmes Autonomes), il est évident que les drones feront partie de la boîte à outils de l'avenir pour les applications militaires et civiles. En visitant l'Exposition universelle de 1964, Isaac Asimov avait imaginé entrevu, 50 ans à l’avance de ce que serait l'Exposition de 2014 ! Ne reconnait-on pas aujourd’hui les systèmes sans pilotes dans les véhicules aux « cerveaux robots » qu’il décrit ?

Néanmoins, de nombreux problèmes techniques, juridiques et éthiques demeurent. L'objectif de cette 2e conférence AETOS est de les aborder. Elle se concentre sur les drones et les technologies support, des environnements logiciels et les questions clés de recherche associées. Un de ses objectifs est de rassembler la communauté et de donner l'occasion de partager les expériences, points de vue et tendances actuelles dans le domaine. Chaque année, de nouveaux sujets sont ajoutés au champ de la conférence ; cette année, il sera aussi question des applications et réels déploiements mondiaux.

Title: Image Based Visual Control of Aerial Robotic Vehicles

Abstract: Robert Mahony Affiliation: Research School of Engineering, Australian National University. Abstract: Vision systems provide a low-cost, light-weight and information rich sensing paradigm that offers significant potential for control of aerial robotic vehicles. Processing vision data to extract state and environment information requires significant computational power. Although recent results using visual SLAM and similar techniques are impressive, there will always be a place for low level visual control of aerial vehicles using simple visual cues that can be computed by embedded vision systems. In this talk I discuss several examples of image based visual control for aerial vehicles, including the use of optic flow for a range of terrain tracking, obstacle avoidance and landing manoeuvres, as well as using more classical image features for position and path control as well as formation control.

Title: Robust aerial docking of a ducted fan

Abstract: This talk focuses on the modeling and control of an innovative configuration of aerial robot obtained by combining a ducted fan aerial vehicle and a robotic arm. The overall system, denoted as aerial manipulator, is able to accomplish operations requiring the physical interaction with the surrounding environment, like docking a vertical surface, while remaining airborne. After introducing a dynamical model of the system and of the environment, a control law based on the impedance control paradigm is presented. The talk also presents possible control paradigms based on switching rules obtained by modeling the aerial system and the surrounding environment as an hybrid automaton.  Particular emphasis will be given to the robustness properties of the control solutions in presence of uncertainties in the environment and in the UAV dynamics. The effectiveness of the proposed control solutions are shown by presenting experimental results obtained within the European project AIRobots (www.airobots.eu).

Title: A Smooth-turn Mobility Model for Airborne Networks

Abstract: The design of effective routing protocols in airborne networks relies on suitable mobility models that capture the movement patterns of airborne vehicles. As airborne vehicles cannot make sharp turns as easily as ground vehicles do, the widely used mobility models developed for Mobile Ad Hoc Networks such as the Random Waypoint and the Random Direction will not be able to appropriately model the movement patterns of airborne vehicles.
In this talk, we introduce a novel mobility model, called the Smooth Turn mobility model that captures the correlation of acceleration of airborne vehicles across time and spatial coordinates. The proposed model is realistic in capturing the tendency of airborne vehicles towards making straight trajectories and smooth turns with large radii, and yet is tractable enough for connectivity analysis and routing protocol design. We first describe the mathematics of this model and then prove that the stationary node distribution of this mobility model is uniform. Moreover, due to the significance of degree of randomness in characterizing mobility pattern and routing protocol design, we introduce a metric to quantify the degree of randomness in mobility models, using entropy rate. Compared to the existing airborne network mobility models such as the flight plan-based model and the semi-random circular movement model, the proposed Smooth Turn mobility model has higher degree of randomness, but is less random than the Random Direction model because of the smooth-trajectory constraint that is unique to airborne vehicles. We conclude this talk with several possible variations to the basic Smooth Turn mobility model.

Title: Estimation and Control toward Autonomous Aerial Robot Systems

Abstract: The applicability of small-scale unmanned aerial vehicles to autonomous inspection, search and rescue, surveillance, and transport is driving rapid growth in the field of aerial robotics. Despite this growth, numerous research questions still exist when considering aerial robot systems in challenging environments at the fundamental levels of dynamics, estimation, and control and at the intersection of these research domains for single or multi-robot systems. In this talk, we discuss recent research with single and multiple aerial vehicles addressing these fundamental topic areas and building upon this work toward fully autonomous aerial systems able to operate in real-world domains. We will discuss topics on control toward aggressive maneuvers with quadrotors, state estimation and autonomous navigation in indoor and outdoor environments, and cooperative formation control and mapping. The talk will span the fundamental dynamics and control considerations required to achieve autonomous flight, continue with state and environment estimation and planning toward full autonomy, and close with a discussion on cooperative multi-robot control and mapping.

Biosketch: Nathan Michael recently joined the Robotics Institute at Carnegie Mellon University as an Assistant Research Professor. Prior to this appointment, he was a Research Assistant Professor in the Department of Mechanical Engineering at the University of Pennsylvania. He received a Ph.D. from the Department of Mechanical Engineering at the University of Pennsylvania in 2008 and transitioned to a position in the Research Faculty in 2010. His research interests include the topics of estimation and control for ground and aerial robots with extensions to multi-robot systems.

Title: Safe operation of UAS systems in risky operations

Abstract: This presentation considers UAS operations involving risk due to environment dynamic interactions.  First it considers the operation of a single UAS in critical operations such as the landing in mobile platforms or even the physical interactions with the environment of aerial robots in manipulation tasks. Then, it will address the cooperation of multiple UAVs in constrained spaces or involving the physical interactions between them, such as in joint load transportation. The presentation will include results of experiments in the indoor testbed of the Center for Advanced Aerospace Technologies and in outdoor flying tests.

Title: Towards a unified approach to the control of aerial vehicles

Abtract: Mechanical design and control of flying machines have historically evolved in parallel. From the middle of last century to these days modern aircraft autopilots have developed on the basis of linearized motion equations and Linear Control Theory. For decades helicopters, whose flight control is more complex than that of airplanes, have been deprived of automatic control devices. It is only recently that the most sophisticated of them have been installed with a variety of devices (attitude retention systems, stability augmentation systems) that assist the human pilot. The development of Unmanned Aerial Devices (UAV) --or drones--, and in particular of Vertical Take-Off and Landing (VTOL) vehicles, has more recently motivated nonlinear control studies. However, most of these studies are based on simplified dynamic models that neglect aerodynamic forces, so that they are not best suited to the control of vehicles moving fast or subjected to strong wind variations. This talk aims at presenting the basic principles of a unified approach to the control of aerial vehicles, either manned or unmanned, with fixed or rotary wings, subjected to varying drag and lift aerodynamic forces.

Biosketch: Claude Samson graduated from the Ecole Supérieure d'Electricité in 1977, and received his Docteur-Ingénieur and Docteur d'Etat degrees from the University of Rennes, in 1980 and 1983, respectively. He joined INRIA in 1981, where he is presently Directeur de Recherche. His research interests are in control theory and its applications to the control of mechanical systems. Dr. Samson is the coauthor, with M. Leborgne and B. Espiau, of the book "Robot Control. The Task-Function Approach" (Oxford University Press, 1991).

Title: Coping with time delay in tele-manipulation of flying vehicles

Abstract: It is well known in control that time delays have a destabilizing effect in a control loop. This is certainly the case when bilateral telemanipulation is implemented. Passivity is an effective tool in order to tackle the problem, but transparency together with the fact that a flying vehicle has pervasive dissipation create extra challenges to the problem. The presentation will introduce a methodology named "two layer approach" which presents a variable solution to the problem of telemanipulation of flying vehicles.
