Full textThis work is based on the multi-agent system / multi-vehicles. This thesis especially focuses on formation control of multiple nonholonomic mobile robots. The objective is to design suitable controllers for each robot according to different control tasks and different constraint conditions, such that a group of mobile robots can form and maintain a desired geomantic pattern and follow a desired trajectory. The leader-follower formation control for multiple nonholonomic mobile robots is investigated under the backstepping technology, and we incorporate a bioinspired neurodynamics scheme in the robot controllers, which can solve the impractical velocity jumps problem. The distributed formation control problem using consensus-based approach is also investigated. Distributed kinematic controllers are developed, which guarantee that the multi-robots can at least exponentially converge to the desired geometric pattern under the assumption of "perfect velocity tracking". However, in practice, "perfect velocity tracking" doesn’t hold and the dynamics of robots should not be ignored. Next, in consideration of the dynamics of robot with unknown parameters, adaptive torque controllers are developed such that the multi-robots can asymptotically converge to the desired geometric pattern under the proposed distributed kinematic controllers. Furthermore, When the partial knowledge of dynamics is available, an asymptotically stable torque controller has been proposed by using robust adaptive control techniques. When the dynamics of robot is unknown, the neural network controllers with the robust adaptive term are proposed to guarantee robust velocity tracking

Full textThe research presented in this report deals with the improvement of the autonomous mobile robots locomotion capacities on natural terrains. In this work, an adaptive locomotion system with a redundant wheel-legged hybrid kinematic structure was designed and realized. Indeed, this kind of mechanism has the capacities to adapt itself to uneven grounds. The autonomy of the robot is linked to both its kinematics capacities of adaptation and to its energetic dependence. When the vehicle reconfigurates itself, while moving on an uneven field, a big amount of energy is needed by its internal mobilities. That is why, a posture control aiming at minimizing the number of reconfigurations of the robot has been developed. The goal is to modify the posture of th erobot only when its integrity, i. E. Its stability is jeopardized. The use of a posture control command law based on the potential fields allow to obtain the wanted behaviour of the robot. The command of the movements of the robot relies on the inverse of the differential kinematic model. In this model, the different terms are split, ensuring so both the trajectory and the change of the posture of th erobot. The robot reconfigurates itself when its stability reached a pre-determined value. The principle of this control is validated through numeric simulations representing the dynamic behavoiur of the robot moving on a natural terrain

Full textEvery year more than 5 million people worldwide become hemiplegic as a direct consequence of stroke. This neurological deficiency, often leads to a partial or a total loss of standing up abilities and /or ambulation skills. In order to propose new supporting solutions lying between the wheelchair and the walker, this thesis comes within the ANR TECSAN project named VHIPOD “self-balanced transporter for disabled persons with sit-to-stand function”. In this context, this research provides some answers for two key issues of the project : the sit-to-stand assistance (STS) of hemiplegic people and their mobility through a two wheeled self-balanced solution. These issues are addressed from a robotic point of view while focusing on a key question : are we able to extend the use of Takagi-Sugeno approach (TS) to the control of complex systems ? Firstly, the issue of mobility of disabled persons was treated on the basis of a self-balanced solution. Control laws based on the standard and descriptor TS approaches have been proposed for the stabilization of gyropod in particular situations such as moving along a slope or crossing small steps. The results have led to the design a two-wheeled transporter which is potentially able to deal with the steps. On the other hand, these results have also highlighted the main challenge related to the use of TS approach such as the conservatisms of the LMIs constraints (Linear Matrix Inequalities). In a second time, a test bench for the STS assistance based on parallel kinematic manipulator (PKM) was designed. This kind of manipulator characterized by several closed kinematic chains often presents a complex dynamical model (given as a set of ordinary differential equations, ODEs). The application of control laws based on the TS approach is often doomed to failure given the large number of non-linear terms in the model. To overcome this problem, a new modeling approach was proposed. From a particular set of coordinates, the principle of virtual power was used to generate a dynamical model based on the differential algebraic equations (DAEs). This approach leads to a quasi-LPV model where the only varying parameters are the Lagrange multipliers derived from the constraint equations of the DAE model. The results were validated on simulation through a 2-DOF (degrees of freedom) parallel robot (Biglide) and a 3-DOF manipulator (Triglide) designed for the STS assistance

Full textThis work investigates the contribution of differential algebra to two main issues of wheel mobile robotics, localization and navigation. The first issue is to be able to tell where the robot is in its environment. We assume that we have a number of landmarks in space whose coordinates are known in this area. Depending on the number of landmarks, it is possible or not to localize the robot. This notion of localizability is defined and studied in the algebraic framework. We show that this framework is more interesting than the geometric framework in the sense that it not only allows the study of localizability, but it also allows us to construct estimators states to reconstruct the posture of the robot. This study was conducted in five cases study for four of the five classes of wheeled mobile robots. The second problem studied is that of a robot decentralized swarm navigation in a complex environment. This work presents an architecture that can be used in a wide class of problems and enjoying the benefits of discrete approaches and continuous approaches. Indeed, high-level block strategy specifies the goal, constraints and parameters as well as the cost function, a low-level block is used to compute a trajectory that minimize the cost function in accordance with the objective and the problem constraints. This minimization is done on a sliding window so it is possible to take changes in the environment or mission during navigation into account

Full textThis thesis focused on the issue of the preseving of the integrity of mobile robots in off-road conditions. The objective is to provide control laws to guarantee the integrity of a vehicle during autonomous displacements in natural environments at high speed (5 to 7 m.s -1 ) and more particularly in The framework of precision farming. Integrity is here understood in the broad sense. Indeed, control of the movements of a mobile robot can generate orders that affect its physical integrity, or restrains the achievement of its task (rollover, spin, control stability, maintaining accuracy , etc.). Moreover, displacement in natural environments leads to problems linked in particular to relatively variable and relatively low adhesion conditions (especially since the speed of the vehicle is high), which results in strong sliding of wheels on the ground, or to ground geometries that can not be crossed by the robot. This thesis aims to determine in real time the stability space in terms of permissible controls allowing to moderate the actions of the robot. After a presentation of the existing modelings and observers that allow the use of these modelizations for the implementation of predictive control law for trajectory tracking, a new method of estimation of side-slip angles based on a kinematic observation is proposed. It permit to address the problem of variable speed of the vehicle (and in particular the case of zero values) and also to allow the observation during a displacement without reference trajectory. This new observer is essential for the further development of this thesis, since the rest of the work is concerned with the modulation of the speed of the vehicle. So, in the further work, two predictive control laws acting on the speed of the vehicle have been set up. The first one provides a solution to the problem of the saturation of steering actuators, when the speed or side-slip angles make the trajectory inadmissible to follow with respect to the physical capacities of the vehicle. The second one adress the problem of guaranteeing the accuracy of trajectory tracking (keeping the vehicle in a corridor of displacement). In both cases, the control strategy is similar: the future state of the vehicle is predicted according to the current conditions of evolution and the simulated one for the future evolution (obtained by simulating the evolution of dynamics models of the vehicle) in order to determine the value of the optimum speed so that the target variables (in one case the value of the steering and in the other the lateral deviation from the trajectory) comply with the imposed conditions (not exceeding a target value). The results presented in this thesis were realized either in simulations or in real conditions on robotic platforms. It follows that the proposed algorithms make it possible : in one case to reduce the speed of the vehicle in order to avoid the saturation of the steering actuator and therefore the resulting over and under steering phenomena and thus make it possible to preserve the vehicle’s controllability. And in the other case, to ensure that the lateral deviation from the trajectory remains below a target value
Guillet, Audrey. "Commande locale décentralisée de robots mobiles en formation en milieu naturel." Thesis, Clermont-Ferrand 2, 2015. http://www.theses.fr/2015CLF22609/document.
Full textThis thesis focuses on the issue of the control of a formation of wheeled mobile robots travelling in off-road conditions. The goal of the application is to follow a reference trajectory (entirely or partially) known beforehand. Each robot of the fleet has to track this trajectory while coordinating its motion with the other robots in order to maintain a formation described as a set of desired distances between vehicles. The off-road context has to be considered thoroughly as it creates perturbations in the motion of the robots. The contact of the tire on an irregular and slippery ground induces significant slipping and skidding. These phenomena are hardly measurable with direct sensors, therefore an observer is set up in order to get an estimation of their value. The skidding effect is included in the evolution of each robot as a side-slip angle, thus creating an extended kinematic model of evolution. From this model, adaptive control laws on steering angle and velocity for each robot are designed independently. These permit to control respectively the lateral distance to the trajectory and the curvilinear interdistance of the robot to a target. Predictive control techniques lead then to extend these control laws in order to account for the actuators behavior so that positioning errors due to the delay of the robot response to the commands are cancelled. The elementary control law on the velocity control ensures an accurate longitudinal positioning of a robot with respect to a target. It serves as a base for a global fleet control strategy which declines the overall formation maintaining goal in local positioning objective for each robot. A bidirectionnal control strategy is designed, in which each robot defines 2 targets, the immediate preceding and following robot in the fleet. The velocity control of a robot is finally defined as a linear combination of the two velocity commands obtained by the elementary control law for each target. The linear combination parameters are investigated, first defining constant parameters for which the stability of the formation is proved through Lyapunov techniques, then considering the effect of variable coefficients in order to adapt in real time the overall behavior of the formation. The formation configuration can indeed be prone to evolve, for application purposes and to guarantee the security of the robots. To fulfill this latter requirement, each robot of the fleet estimates in real time a minimal stopping distance in case of emergency and two avoidance trajectories to get around the preceding vehicle if this one suddenly stops. Given the initial configuration of the formation and the emergency behaviors calculated, the desired distances between the robots can be adapted so that the new configuration thus described ensures the security of each and every robot of the formation against potential collisions

Full textThe problem of this thesis concerns the control of the movements and the equilibrium of humanoid robots that have a mobile base with omnidirectionnal wheels. The developed methods aim to reach high dynamical performances for this type of robot, while ensuring it stability and equilibrium. Humanoid robots have generally a center of mass relatively high compared to its contact surface with the ground. Therefore, the slightest acceleration of the robot bodies induces a large variation of the distribution of the contact forces with the ground. If they are not properly controlled, the robot can fall. Moreover, the robot having a mobile base with wheels, a disturbance can easily bring it to tilt on two wheels. Finally, a specific interest have been provided about the realisation of a real time controler implemented on the embedded system of the robot. This implies some constraints about the computationnal time of the control law. In order to answer these problems, two linear models of the robot have been developed. The first allows to modelize the dynamics of the robot when it has all of its wheels in contact with the ground. The second allows to modelize the dynamics of the robot when it tilts on two of its wheels. These models have been developed by taking into account the mass distribution of the robot. These models have been subsequently used in two predictive control laws, allowing to take into account at every instant the dynamical constraints as weel as the future behavior of the robot. The first allows to control the movements of the robot when it has all of its wheels in contact with the ground, preventing it for tilting. The second allows the robot to recover itself in a situation when a disturbance bring it to tilt, in order to bring back all of its wheels in contact with the ground. Also, a supervisor that has a state machine has been made in order to define which control law has to be executed at each instant. This supervisor uses the available sensors on the robot in order to observe its tilt state. Finally, in order to validate experimentally the results of the developments of this thesis, a series of experiments has been presented, demonstrating some aspects of the control law. In particular, some tests have been made concerning the tracking of non physically feasible trajectories, the reject of disturbances applied on the mobile base, the stabilisation of the robot during its tilt, and the compensation of the variations of the ground inclination

Full textThe research presented in this thesis report focuses on the optimization of crossing capabilities for "wheel-legged" hybrid mobile robots. We consider that a robot is able to overcome an obstacle if he is able, for each geometric configuration of the contact points encountered during the crossing , to balance the external forces applied to it while maintaining contact adhesion. Our approach consist in using two features of poly-articulated robots in order to optimize the distribution of contact forces. Firstly, the actuation redundancy allows the application of internal forces. Secondly, the kinematic redundancy allows to change the CoM position, changing the set of possible solutions to the force distribution problem. The criterion used for the optimization measures the contacts stability robustness relatively to uncertainties in the force control. It was chosen based on a comparative analysis of different criteria used in the field of grasping. The resulting control algorithm allows for simultaneous control of both robot movements and contact forces. Experimental results on robot HyLoS 2 show that the algorithm allow for the crossing of an obstacle represented by a slope of 60\char6 with a height of 19 cm, while the wheels radius is only 7 cm

Full textThis project is concerned with an investigation of simple communication between ANN-controlled mobile robots. Two robots are trained on a (seemingly) simple navigation task: to stay close to each other while avoiding collisions with each other and other obstacles.
A simple communication scheme is used: each of the robots receives some of the other robots’ outputs as inputs for an algorithm which produces extra inputs for the ANNs controlling the robots.
In the experiments documented here the desired cooperation was achieved. The different problems are analysed with experiments, and it is concluded that it is not easy to gain cooperation between autonomous mobile robots by using only output from one robot as input for the other in ANNs.

Full textThis work addresses the automatic control problem of wheeled mobile robots via the higher order sliding mode approach. After presenting aspects of modelling of wheeled mobile robots, as flatness approach to planning, different sliding mode control strategies are elaborated. Under the assumption of pure rolling of wheels without sliding (non holonomic constraints satisfied), the first strategy solves the problem of the stabilization of the car at a fixed point by switching of control laws between second and third order sliding mode controllers. The latter is based on geometric homogeneity property with a discontinuous term. The second strategy solves the problem of the trajectory tracking. Two second order sliding mode control laws are then developed. The first rests on the Lyapunov type approach, while the second uses the input/output linearization techniques of flat systems. Both control laws have been tested in simulation and validated experimentally on the platform Robucar. In order to study the robustness of our approach to unmatched disturbances (sliding and skidding effects of the wheels), a third higher order sliding control strategy is proposed. In the case of pseudo-sliding, we have developed for the unicycle and the car a control law based on the sliding surfaces ensuring the asymptotic convergence of both lateral and longitudinal errors. However, due to the sliding and the skidding effects, those errors are only stabilized in an arbitrarily small neighborhood of the origin

Full textThis dissertation work addresses the obstacle avoidance for wheeled mobile robots. The supervisory control framework coupled with the output regulation technique allowed to solve the obstacle avoidance problem and to formally prove the existence of an effective solution: two outputs for two objectives, reaching the goal and avoiding the obstacles. To have fast, reliable and robust results the designed control laws are finite-time, a particular class very appropriate to the purpose. The novelty of the approach lies in the easiness of the geometric approach to avoid the obstacle and on the formal proof provided under some assumptions. The solution have been thus extended to control a leader follower formation which, sustained from the previous result, uses two outputs but three controls to nail the problem. The Leader role is redesigned to be the reference of the group and not just the most advanced agent, moreover it has a active role slowing down the formation in case of collision avoidance manoeuvre for some robots. The proposed method, formally proven, makes the group move together and allow each agent to avoid obstacles or collision in a decentralized way. In addition, a further contribution of this dissertation, it is represented by a modification of the well known potential field method to avoid one of the common drawback of the method: the appearance of local minima. Control theory tools helps again to propose a solution that can be formally proven: the application of the definition of Input-to-State Stability (ISS) for decomposable sets allows to treat separate obstacles adding a perturbation which is able to move the trajectory away from a critic point

Full textCloud robotics is a modern approach to robotics based on cloud computing, cloud storage and other Internet services that robots can benefit from to overcome fundamental limitations in on-board computation and memory scalability. This new subfield of robotics is driven by the rapid progress of wireless communications and easy-toaccess cloud infrastructure provided by large industries such as Google, Amazon, and Microsoft. The goal of this project consists of the design and implementation of a prototype for indoor mobile robot localization with RGB-D cameras leveraging the cloud. Localization is a fundamental problem in autonomous robotics surveyed in this report. In addition, extraction of features for localization from depth images is also addressed. As a result of this project, a new system for cloud-based robot localization is presented. The system makes use of modern opensource software such as ROS and GraphLab. Finally, experiments are presented to analyse the improvements and limitations achieved by our approach.

Full textWe developed a mobile robot system for teleoperation using a robot mounted camera as a primary sensor. This system functions in a partially-known environment for which a 3D geometric map is available. In this thesis we describe aspects of the system related to enhanced reality, that is the augmentation of the returned video data with information extracted from the world knowledge base. If during robot navigation our sensor data (returned video) experiences transmission delays or becomes too noisy or obstructed, we superimposed artificially generated graphics (using the model representation) onto a regular video picture. Once a clear transmission was recaptured or the obscuring obstacle shifted from its old position, video data covering that area of the image was redisplayed for consequent navigation. This task of fusing these two representations together simultaneously, in an efficient and realistic fashion during robot teleoperation, was the goal of our research.

Full textPosition calculation of mobile objects has challenged engineers and designers for years and is still continuing to do so. There are many solutions available today. Probably the best known and most widely used outdoor system today is the Global Positioning System (GPS). There are very little systems available for indoor use. An absolute positioning system was developed for this thesis. It uses a combination of ultrasonic and Radio Frequency (RF) communications to calculate a position fix in doors. Radar techniques were used to ensure robustness and reliability even in noisy environments. A small mobile robot was designed and built to test and illustrate the use of the system.
