Full textWe describe models and algorithms designed to produce efficient and physically consistent dynamic simulations. These models and algorithms have been implemented within the RobotΦ system\cite(RAP95) which can potentially be configured for a large variety of interven\-tion-style tasks such as dextrous manipulations with a robot hand; manipulation of non-rigid objects; tele-programming of the motions of an all-terrain vehicle; and some robot assisted surgery tasks (e. G. Positioning of an artificial ligament in knee surgery). The approach uses a novel physically based modeling technique to produce dynamic simulations which are both efficient and consistent according to the laws of the Physics. The main advances over previous works in Robotics and Computer Graphics fields are twofold: the development of a unique framework for simultaneously processing motions, deformations, and physical interactions; and the incorporation of appropriate models and algorithms for obtaining efficient processing times while insuring consistent physical behaviors

Full textA key challenge for autonomous systems is operating under real-world uncertainties. Robots rely on models of their environment and themselves for decision- making, but these models are inherently approximations. Consequently, uncertain parameters can lead to significant discrepancies be- tween the intended and actual system behavior. This thesis addresses the issue of para- metric uncertainties by developing trajectories that are intrinsically robust. Through optimizing these trajectories within the closed-loop system using novel concepts of state and in- put sensitivities introduced in this work, the approach enhances robot performance in uncertain conditions. The primary goal of this thesis is to extend and apply these sensitivity-based methods for robust trajectory planning. The validity of the proposed optimization frame- work is empirically assessed through extensive statistical campaigns, both in simulations and real-world experiments, on two widely- used robotic platforms: a quadrotor drone and a robotic manipulator

Full textControl system theory has first been built for analog controllers. In this context, it was relevant to use a continuous framework to design a control feedback function. Nowadays, digital technologies are supplanting analog solutions due to several advantages (cost, noise, resistance, integration...). Signal is held constant between periodic triggers given by a digital clock.Event-based (or event-triggered) control aims to improve the periodic sampling scheme by proposing a method in which updates are triggered by an event function.In this thesis new event-based designs are detailled and tested on real-time systems.The most original contribution of this thesis is the use of an event-triggered design for a problem of collision avoidance between a quadrotor and a known environment

Full textThe classical approach for Multi-Agent System (MAS) Control, especially autonomous and robotic ones, deals first from a microscopic point of view: each agent embed a control program with communication/synchronization primitives that enable cooperation between agents. The emergence of a global behaviour from a macroscopic point of view can only be observed afterwards. In this context, MASL offers a macroscopic and unified approach with heterogeneous and distributed calculations over deliberative, reactive or hybrid agents. In this high level language, regardless of the runtime, each concurrent agent locally decides its participation in a collective execution block named an e-block. Each e-block is an anonymous collective program that runs over an agent network following local conditions. The orchestral mode (scalar, asynchronous, synchronous) is statically fixed by a shared block attribute. The communication use shared memory, events, synchronous messages passing, and asynchronous messages passing. Heterogeneous agents are managed with heritage and polymorphism. Permeability mechanism, dealing with agent autonomy, allows an agent to dynamically filter calls to its interface in respects to the sender position in the e-block hierarchy. In dynamic task allocation of agents, auto failover and recovery, agent replacement in a robot fleet (case of agent failure, loss of a mandatory functionality for the mission) an e-block is an entry point of a collaborative work. In the case of synchronous e-block, the programming paradigm is the data parallel model with iterative task for waves of agents. Finally, MASL offers advances in the field of MAS (dynamic belonging to groups, accuracy of the pace of actions to undertake to enable a desired cooperation) and for the management of errors

Full textRobotics has experienced an increasing evolution and interest from the society in recent years. Robots are no longer produced exclusively to perform repetitive tasks in factories, they have been designed to collaborate with humans in several important application domains. Robotic systems that control these robots are therefore becoming larger, more complex, and difficult to develop. In this scenario, Service-Oriented Architecture (SOA) has been investigated as a promising architectural style for the design of robotic systems in a flexible, reusable, and productive manner. Despite the existence of a considerable amount of Service-Oriented Robotic Systems (SORS), most of them have been developed in an ad hoc manner. The little attention and limited support devoted to the design of SORS software architectures may not only hamper the benefits of SOA adoption, but also reduce the overall quality of robotic systems, which are often used in safety-critical contexts. This thesis aims at improving the understanding and systematization of SORS architectural design

Full textThe discovery of sensorimotor contingencies and their structurationinto skills are both important topics in the field of robotics. In particular,robots need the ability to learn skills which are both semantically rich and as general as possible. During this thesis, we studied the question of merging robotic skills into more general skills. After formally defining the notions that can be found in the litterature of skills and parameterized skills, we established a link between paramaterized skills and inverse models, then mirrored the dualism between forward and inverse models to propose a dual type of parameterized skills:forward-parameterized skills. We went on to determine when merging skills into a forward-parameterized skill is relevant and when it’s not. The problem is then formulated as a regression problem, and algorithms inspired by the Occam Razor principle are proposed to find a mixture of experts that solves it with minimal complexity. Those algorithms are then applied to simulated object-manipulation data

Full textThis work seeks to mitigate the effects of constraints on mobile robotic systems. To this end, auxiliary control loops and robust tuning techniques are proposed. The former are proposed to mitigate the effects of constraints on the input and output of the systems through the modification of the motion parameter in path following applications.Then, PID controllers are considered as a structural constraint, given its wide use in robotics particularly at low control level. A robust tuning methodology considering this constraint is proposed which achieves good performancelevels even when facing disturbances. Finally, to deal with robustness in presence of robots nonlinearity constraints, an analysis and tuning tool for sliding mode controllers is proposed. The particularity of this tuning method, based on global optimization and interval techniques,is that it allows generating tuning maps of the parameter regions where the desired performance criterion is fulfilled. All the proposed strategies are put into practice, through real experimentation or invalidated simulators, over the AUV Ciscrea available at ENSTA Bretagne

Full textThanks to the advances in the fields of robotics and intelligent transportation systems (ITS), the autonomous vehicles of the future are gradually becoming a reality. As autonomous vehicles will have to behave safely in presence of other vehicles, pedestrians and other fixed and moving objects, one of the most important things they need to do is to effectively perceive both their motion and the environment around them. In this thesis, we first investigated how bio-inspired visual sensors, giving 1-D optic flow using a few pixels based on the findings on the fly’s visual system, could be used to improve automatic parking maneuvers. We subsequently tested a novel bio-inspired silicon retina, showing that the novel pixel, called M2APix, can auto-adapt in a 7-decade range and respond appropriately to step changes up to ±3 decades, while keeping sensitivity to contrasts as low as 2%. We lastly developed and tested a novel optic flow sensor based on this auto-adaptive retina and a new robust method for computing the optic flow, which is robust to the light levels, textures and vibrations that can be found while operating on the road. We also constructed a car-like robot, called BioCarBot, which estimates its velocity and steering angle by means of an extended Kalman filter (EKF) using only the optic flow measurements delivered by two downward-facing sensors of this kind

Full textToday, robotic manipulators are being called upon to perform an increasingly wide range of tasks that extend beyond the conventional ones required in traditional applications. One such type of application is physical human-robot interaction. In order for such systems to be safe, it can be desirable to decrease their weight and strength by reducing the size of their actuators.Indeed, reducing the size of the actuators increases safety in two manners, the inertia of the manipulator decreases and the torques generated by the motors are greatly reduced. However, the main drawback of such manipulators is the reduction of their payload capacity.Therefore, better usage of the limited joint efforts is required to enable them to perform tasks that they would normally not be able to accomplish. Thus, this thesis presents a study of two main types of tasks where an effective trajectory optimisation strategy can be particularly valuable. The first task is that of lifting heavy objects, i.e., objects that exceed the conservative estimate of the payload capacity of a manipulator. Studying this task could lead to the design of lighter,more capable manipulators. This work focuses on studying trajectory generation methods to enable manipulators with relatively weak actuators to lift heavy payloads by fully utilizing their dynamics. The second task studied in this thesis is the task of throwing objects. Specifically, the distance throwing capabilities of manipulators is studied where the maximum distance that an object can be thrown with a given manipulator is sought. This task is studied at three levels of complexity: finding the maximum possible throwing capacity of manipulators with velocity constraints, finding the maximum throwing capacity considering a full trajectory with kinematic constraints, and finding the maximum throwing capacity considering a full trajectory with dynamic constraints. Finally, performance criteria are established from these two types of tasks in order help in the process of designing a new manipulator. Thus, a simple design optimisation simulation is performed as a proof of concept.

Full textThis thesis is part of the European project VERE (Virtual Embodiment and Robotics re-Embodiment). The goal is to propose a software framework integrating a set of control strategies and information feedback based on the "task function" in order to embody a human operator within a humanoid robot or a virtual avatar using his thoughts. The underlying problems can be shown by considering the following demonstrator. Let us imagine an operator equipped with a brain-computer interface; the goal is to extract the though of the human operator from these signals, then translate it into robotic commands and finally to give an appropriate sensory feedback to the operator so that he can appropriate the "body", robotic or virtual, of his avatar. A cinematographic illustration of this objective can be seen in recent movies such as "Avatar" or "Surrogates". In this thesis, we start by discussing specific problems that we encountered while using a brain-computer interface for the control of robots or avatars, e.g. the arising need for multiple behaviours or the specific problems induced by the sensory feedback provided by the robot. We will then introduce our main contribution which is the concept of object-oriented brain-computer interface for the control of humanoid robot. We will then present the results of a study regarding the role of sound in the embodiment process. Finally, we show some preliminary experiments where we used electrocorticography (ECoG)~--~a technology used to acquire signals from the brain that is implanted within the cranium~--~to control a humanoid robot

Full textThe goal of this thesis is to add to the efforts toward the long-sought objective of secure and safe robots with predictable and a priori known behavior. For the reasons given above, formal methods are used to model and verify crucial properties, with a focus on the functional level of robotic systems. The approach relies on automatic generation of formal models targeting several frameworks. For this, we give operational semantics to a robotic framework, then several mathematically proven translations are derived from such semantics. These translations are then automatized so any robotic functional layer specification can be translated automatically and promptly to various frameworks/languages. Thus, we provide a mathematically correct mapping from functional components to verifiable models. The obtained models are used to formulate and verify crucial properties (see examples above) on real-world complex robotic and autonomous systems. This thesis provides also a valuable feedback on the applicability of formal frameworks on real-world, complex systems and experience-based guidelines on the efficient use of formal-model automatic generators. In this context, efficiency relates to, for instance, how to use the different model checking tools optimally depending on the properties to verify, what to do when the models do not scale with model checking (e.g. the advantages and drawbacks of statistical model checking and runtime verification and when to use the former or the latter depending on the type of properties and the order of magnitude of timing constraints)

Full textThe objectives of our work were, on the one hand, to determine the impact of data-transmission latency in robotic telesurgey, and on the other hand, to validate the role of robotic simulator in robotic surgery training. Two studies were realized in the part concerning latency. It was proved that surgical performance deteriorates exponentially as latency increases. It is preferable to perform telesurgey with a delay less than 200 ms. The delay higher than 800 ms is not suitable for telesurgery. On the other hand, surgeons had demonstrated the capacity to adapt to delay through training. In the second part, we developed a curriculum on a robotic simulator for a urologic surgical procedure. Another study was realized to determine the validity of a new robotic simulator (the XTT) as an evaluation tool of robotic surgical assistance skills

Full textImprovement of the robot’s performances is a major challenge in the industrial field. In general, improvement objectives are increasing workspace, transportable capacity, speed and precision of the robot. To achieve these objectives, it must increase rigidity, reduce weight and increase damping capacity of the robot. Currently, the robots are generally made of metals: aluminum or steel, which limits their performances due to low damping capacity of these materials.Composite materials present an advantage to combine different materials, which leads to a variety of composite material properties. Among the types of reinforcements, carbon fibers show high modulus that enables robotic parts with high static rigidities to be designed. However, carbon fibers have generally a low damping capacity. Natural fibers have low density, good specific properties and high damping capacity.This thesis focuses on the improvement of the performances of the 3CRS parallel robot by using the composite material to redesign robot parts initially made of aluminum. The thesis begins with static and dynamic characterizations of the original robot. Then, the shape of segments of the robotic arms is optimized with respect to applying force on the robot. A hybrid laminated composite reinforced with carbon fibers and flax fibers is proposed for the use. This combination enables to combine the advantages of two fiber types in a composite for using in high loaded components. The structure of the new hybrid laminated composite is optimized and a composite segment is then fabricated in order to validate the design. Finally, the analysis of the new robot with composite arms is executed. The result shows that the new robot has a slightly higher rigidity, lighter mass and considerably greater damping capacity in comparison with the original robot. Therefore, the application of the hybrid composite could improve the static and dynamic performances and increases considerably the accuracy in operation of the robot 3CRS

Full textInspired by the optical properties of the fly compound eyes and the observation of its retinal periodic micro-movements, several visual sensors established that the localization of a contrast can be made very precisely. It was the first demonstration of the visual hyperacuity of the fly compound eye.In this thesis, an artificial compound eye with a wide field of view was used. Thanks to a novel algorithm fusing the visual signals, the sensor embedded onboard an aerial robot measures its displacement and enables the robot to hover above a textured environment.The localization of a contrast precisely over the whole field of view is still difficult. A second algorithm improved the localization of a bar thanks to a calibration. But it has a dependency to the contrast and the illuminance variations.In order to avoid a calibration process, a third algorithm was proposed to localize two contrasts. It is based on the work of Heiligenberg and Baldi, which showed that an array of Gaussian receptive field can provide a linear estimation of a stimulus position. For the first time, we applied a modified version of their estimation to an artificial compound eye. This sensor mounted on a rover allows following a target precisely at a constant distance.Finally, an artificial compound eye with a coarse spatial resolution can be endowed with hyperacuity and enables a robot to follow a target with precision. A step forward has been made toward bio-inspired target localization and pursuit

Full textOne of the most challenging tasks in software engineering for multi-agent robotic systems is to ensure correctness properties of safety and liveness. As these systems have concurrency, and often have dynamic environments, the formal specification and verification of these systems along with step-wise refinement from abstract to concrete concepts play a major role in system correctness. The problem statement is: How can a safe multi-agent robotic system be developed? Here by safe the focus is on correctness properties which can be described by a combination of safety and liveness. How can safety and liveness properties be enforced during the development of multi-agent robotic system? Our objectives are to propose a development approach based on a combination of methods and techniques that allow for formal verification and evaluation during specification definition and that is also flexible. An approach which supports analysis with respect to functional, as well as non-functional properties by step-wise refinement from abstract to concrete specifications and then formal verification of these specifications. We have analysed the development process of a robotic multi-agent system after classifying it in the major phases of requirement specifications, verification specifications, architecture specifications and implementation. Formal methods and languages are based on a solid mathematical foundation. To catch up with the complexity problems in multi-agent systems and get significant results with formal analysis, we must cope with complexity at every stage of development: from the specification phase to the analysis, design and verification phase. Formal verification can be used for exhaustive investigation of system space thus ensuring that undetected failures in the behaviour are excluded. We construct the system incrementally from subcomponents, based on software architecture. State reduction is achieved by hiding actions and minimising; property checks remain in the minimised subcomponents. Each component of a specification is described as LTS, which has all the possible states a component may reach and all possible transitions it may perform. The reasons for having a formal foundation for the languages and tools are: (1) to enable rigorous analysis of system properties; (2) to be as certain as possible that the specifications, transformations, and implementation are property-preserving and error-free; (3) to improve rigor and quality of the whole development process; (4) to provide a firm foundation during the adaptation and evolution process; (5) to improve documentation and understanding of specifications. A solution has been proposed for formal specification and verification of safety and liveness properties. Our contributions are (1) an approach based on a combination of methods to allow for formal verification and evaluation during requirement specifications, verification specifications, architecture specifications, and implementation; (2) checking safety and liveness properties of correctness during each development phase; (3) a multi-agent robotic system case study to exemplify formal specifications and verification; (4) a combination of process algebra and finite automata based techniques to define the formal specifications of our system, using a model-checking method and verifying all possible flow of concurrent executions; (5) identifying the benefits of formal methods for multi-agent robotic systems. We have used the Gaia multi-agent method for requirement specifications; Labelled Transition Systems (LTS) based finite automata techniques, which take Finite State Process (FSP) as input language for verification specification; The π-ADL dot NET is used to define architecture specifications and check the static, as well as dynamic aspects of architecture; Then the system is implemented by using Service-Oriented Architecture (SOA) based Microsoft Robotics Developer Studio (MRDS) simulation environment

Full textOver the last years, autonomous navigation for mobile robot systems has known an increasing interest from the scientific community. This is mainly due to the diversity of its applications and the different challenges that it represents. Without any human intervention, autonomous navigation must be safe, reliable and accurate. Nevertheless, it may be subject to various degradations that could compromise its objective. Indeed, external disturbances, as well as sensor and actuator faults, may affect the different aspects of autonomous navigation, which are localization, path planning and trajectory tracking. This is why we are devoting this thesis to the design of new algorithms that contribute to make the navigation system robust against external disturbances and tolerant to sensor and actuator fauts. We have adopted a residual generation based fault-diagnosis strategy combined with a robust sliding mode controller that is robust against a certain class of perturbations that are not necessary uniformly bounded. The proposed diagnostic layer is purely informational. It is based on the use of two information filters with different evolution models, and the divergences of Bhattacharyya and Kullback-Leibler for residual design. These residuals are evaluated using statistical methods, in order to detect, isolate then exclude sensor and actuator faults from the navigation system. The proposed approach is applied to different differential drive mobile-robot systems. Experimental results obtained by using the CRIStAL robotic platform, so-called PRETIL, are presented and discussed

Full textRobotic systems that continuously adapt to their environment and physically interact with human are increasingly used in various fields like personal assistance or factory work. They are characterised by their ability to adapt to the environment, to take decision in the light of their perception of the environment and particularly of the human. As the failure of such systems may lead to catastrophic consequences, analysis and justification of the level of confidence in these systems with regards to safety, and furthermore their certification is a real challenge. The construction of a Safety Case is one of the means that can be used to support the certification of such systems. It is aimed at describing and justifying how every hazard has been mitigated and its severity maintained as low as reasonably possible. However, for robotic systems that have to deal with many uncertainties, there is a lack of a systematic approach to support the construction of their Safety Case and the assessment of its underlying confidence. Our research aims at contributing to the development of such a systematic approach starting with a risk analysis focusing on human-robot interactions, followed by Safety Case construction from formalized models and finally an automatic assessment of the confidence in safety argumentation. As a case study, the safety of a rehabilitation robot for strolling is analysed and justified based on the approaches developed in this thesis

The work of thisthesis focuses on solving a specific industrial case, which is unresolved and of practical interest :the assembly of heavy-duty tire treads, the part that comes into contact with the road, which isstill a manual process. This industrial process is proposed by the industrial partner Michelin wi-thin the SoftManBot consortium, a Horizon20 program of the European Union with the ambitionto automate the industrial production of deformable objects. The manipulation of deformable ob-jects raises several problems that rigid objects do not present : a modeling problem, a perceptionproblem, a shape servoing problem, and a system engineering problem to make all the precedingcomponents work together.In this thesis, we propose two major contributions. The first one, Optimal Shape Servoing, is astate feedback control based on optimal control that improves the state of the art in shape controlby adding an implicit management of the deformation trajectory - how the object reaches its finaldeformation. Furthermore, the control strategy allows for decoupling and weighting shape andposition errors. Finally, this thesis presents a demonstration-based learning of controller parametersusing a genetic algorithm to mimic the behavior of an object manipulated by a human, in orderto reproduce this deformation during manipulation tasks. Identifying these parameters throughmachine learning strategies combines the best of both worlds - both explainable operation andbehavior close to that performed by a human.Our second contribution, Holistic Architecture for Deformable Object Software, addresses thesystem engineering problem by proposing a modular software architecture that formalizes theneeds and interfaces required for deformable object manipulation problems, both in the labora-tory and in an industrial context, from user interface to gripper drivers. This architecture has beenvalidated and tested through the integration of numerous software components - models, controls,perception, user interfaces, robot controllers, camera drivers, gripper drivers. These componentsare objectively compared using industrial metrics governing the quality of a final product, allowingnot only the automation of the proposed task but also the selection of the most suitable combinationof modules for the same task

Full textThis thesis focuses on exploring unknown environments using a group of reactive autonomous robots. Autonomous exploration is used in different domains, from vacuum robots to search and rescue robots used in natural disasters (fires, landslides) or military contexts.The work achieved during this thesis was financed by Safran Electronics & Defense in support of the FURIOUS project (FUturs Innovative Robotic Systems as Tools for the benefit of the embarked and disembarked fighter) of the French General Direction of Armaments. It follows the Cart-O-Matic project, which was one of the five projects founded by the French National Research Agency (ANR) for its participation in the robotics competition "Défi CAROTTE" organized by the "Direction Générale pour l'Armement," and which won this competition.Many approaches to autonomous exploration exist in the state of the art. In this thesis, we have tried to efficiently explore an indoor environment while limiting the amount of computation and communication. Reducing the amount of computation required saves robot batteries and makes it easier to use a large number of robots. Reducing communications saves energy but is also interesting in a military setting to limit the risks of compromising the presence of robots. A local exploration algorithm has been proposed to significantly reduce communications and computations while maintaining a high level of performance and was published at the 27th Journées Francophones sur les Systèmes Multi-Agents.We then proposed a new semantic map approach, allowing us to segment the environment into rooms and corridors, and a new constraint-based exploration algorithm. This new approach allows robots to understand better the environment in which they evolve and to reduce localization and perception errors specific to the sensors which equip them. Our constraint-based approach allows operators to define robot objectives and priorities better, thus meeting the operational needs of various missions, including search and rescue and military support

Full textMobile robotic systems are becoming more and more complex with the integration of advanced sensing and acting components and functionalities to perform the real required missions. For these technical systems, the requirements are divided into two categories: functional and non-functional requirements. While functional requirements represent what the robot must do to accomplish the mission, non-functional requirements represent how the robot performs the mission. Thus, the quality of service and energy efficiency of a robotic mission are classified in this category. The autonomy of these systems is fully achieved when both functional and non-functional requirements are guaranteed without any human intervention or any external control. However, these mobile systems are naturally confronted with resource availability and energy capacity constraints, particularly in the context of long-term missions, these constraints become more critical. In addition, the performance of these systems is also influenced by unexpected and unstructured environmental conditions in which they interact. The management of resources and energy during operation is therefore a challenge for autonomous mobile robots in order to guarantee the desired performance objectives while respecting constraints. In this context, the ability of the robotic system to become aware of its own internal behaviors and physical environment and to adapt to these dynamic circumstances becomes important.This thesis focuses on the quality of service and energy efficiency of mobile robotic systems and proposes a hierarchical run-time management in order to guarantee these non-functional objectives of each robotic mission. At the local management level of each robotic mission, a Mission Manager employs a reinforcement learning-based decision-making mechanism to automatically reconfigure certain key mission-specific parameters to minimize the level of violation of required performance and energy objectives. At the global management level of the whole system, a Multi-Mission Manager leveraged rule-based decision-making and case-based reasoning techniques monitors the system's resources and the responses of Mission Managers in order to decide to reallocate the energy budget, regulate the quality of service and trigger the online learning for each robotic mission.The proposed methodology has been successfully prototyped and validated in a simulation environment and the run-time management framework is also integrated into our real mobile robotic system based on a Pioneer-3DX mobile base equipped with an embedded NVIDIA Jetson Xavier platform
