Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In this technical report, we investigate modeling, control, and coordination of mobile manipulators. A mobile manipulator in this study consists of a robotic manipulator and a mobile platform, with the manipulator being mounted atop the mobile platform. A mobile manipulator combines the dextrous manipulation capability offered by fixed- base manipulators and the mobility offered by mobile platforms. While mobile manipulators offer a tremendous potential for flexible material handling and other tasks, at the same time they bring about a number of challenging issues rather than simply increasing the structural complexity. First, combining a manipulator and a platform creates redundancy. Second, a wheeled mobile platform is subject to nonholonomic constraints. Third, there exists dynamic interaction between the manipulator and the mobile platform. Fourth, manipulators and mobile platforms have different bandwidths. Mobile platforms typically have slower dynamic response than manipulators. The objective of the thesis is to develop control algorithms that effectively coordinate manipulation and mobility of mobile manipulators. We begin with deriving the motion equations of mobile manipulators. The derivation presented here makes use of the existing motion equations of manipulators and mobile platforms, and simply introduces the velocity and acceleration dependent terms that account for the dynamic interaction between manipulators and mobile platforms. Since nonholonomic constraints play a critical role in control of mobile manipulators, we then study the control properties of nonholonomic dynamic systems, including feedback linearization and internal dynamics. Based on the newly proposed concept of preferred operating region, we develop a set of coordination algorithms for mobile manipulators. While the manipulator performs manipulation tasks, the mobile platform is controlled to always bring the configuration of the manipulator into a preferred operating region. The control algorithms for two types of tasks -- dragging motion and following motion -- are discussed in detail. The effects of dynamic interaction are also investigated. To verify the efficacy of the coordination algorithms, we conduct numerical simulations with representative task trajectories. Additionally, the control agorithms for the dragging motion and following motion have been implemented on an experimental mobile manipulator. The results from the simulation and experiment are presented to support the proposed control algorithms."

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An integrated methodology for trajectory planning and tracking control has been a key need in the research of mobile robots that have a wide range of applications. Problems of planning and control can be considerably simplified if the system can be shown to have the differential flatness property. This thesis discusses how differential flatness theory can be used for planning and control of various types of mobile robots as an integrated framework. Three common types of mobile robots are proven to be differentially flat, and the property is used for planning and control for their kinematic and dynamic models. The mobile robots can have more practical applications if a manipulator arm is mounted on them. While mobile manipulators are usually designed with a fully actuated arm, under-actuation can be a viable solution to reduce the manufacturing and operating costs. Despite the under-actuation, which makes the system more difficult to plan and control, using the differential flatness theory, mobile manipulators can be designed to be capable of executing point-to-point maneuvers as a mobile manipulator with a fully actuated arm would do. The differential flatness property is achieved by inertia redistribution, with addition of torsional springs at un-actuated joints, and a wide range of designs is possible. Using this design methodology, either a two-wheeled differentially driven mobile robot or a car-like mobile robot can be used as the mobile base and the under-actuated manipulator arm can be mounted either horizontally or vertically on the mobile base. The structure of the differential flatness framework for integrated trajectory planning and control is extended to account for slip disturbances within the model. A feasible desired trajectory and the nominal control were determined for the model with slip, then a corrective control was added based on Lyapunov theory to overcome the disturbances due to the slip. The robust trajectory-tracking controller was developed based on the system's dynamic model as well as its kinematic model in the presence of slip. The simulation and experimental results validate the effectiveness of the proposed methodology and show that differential flatness presents a valuable and effective framework for integrated planning and control of mobile robots.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, there has been considerable research performed in the area of mobile manipulators subject to kinematic constraints. This thesis addresses the position control problem of mobile manipulators subject to kinematic constraints. The main objective is to develop practical controllers that can be easily implemented on a mobile manipulator in the presence of parameter uncertainty and unmodeled disturbances, such as terrain irregularity and unknown payload. In this thesis, two mobile manipulator controllers are developed: (i) a neural network-based hierarchical intelligent controller; and (ii) a hierarchical robust controller, each aiming at different control purposes. The proposed hierarchical intelligent controller is based on 'radial basis functions'. As such it has very good learning ability and adaptability, thus it is especially suitable for applications where mobile robots move in unknown and changing environments. When the adaptability is less demanding ('e.g.', the environment is partially or completely known), or when the available system resources, such as size of embedded memory and on-board computational capability are restricted, the hierarchical robust controller is suggested as an alternative. It has a simple control structure and a low computational load. Both proposed controllers require the measurement of velocity signals. In practice, velocity sensors may have to be omitted due to considerations of size and weight. In this case the velocity signals are determined by a first-order numerical differentiation of available position signals. This may introduce significant noise in the control signal and degrade its performance. To resolve this problem, in this thesis we propose a new reduced-order adaptive observer-based velocity measurement technique requiring only position measurements. Rigorous stability and performance analysis of the developed theory is also provided in the thesis. In addition, extensive experiments were conducted on a four-degree-of-freedom robotic manipulator. The experimental results validate the effectiveness of the proposed controllers.

Autonomous vehicles are currently being studied for use as reconnaissance/exploratory vehicles for planetary exploration, undersea, land and air environments, remote repair and maintenance, material handling systems for offices and factories, and even intelligent wheelchairs for the disabled. This reference is the first to deal directly with the unique and fundamental problems and recent progress associated with autonomous vehicles. The editors have assembled and combined significant material from a multitude of sources, and, in effect, now conviniently provide a coherent organization to a previously scattered and ill-defined field.
Download or read book Kinematic Control of Redundant Mobile Manipulators written by Mustafa Mashali and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A mobile manipulator is a robotic arm mounted on a robotic mobile platform. In such a system, the degrees of freedom of the mobile platform are combined with that of the manipulator. As a result, the workspace of the manipulator is substantially extended. A mobile manipulator has two trajectories: the end-effector trajectory and the mobile platform trajectory. Typically, the mobile platform trajectory is not defined and is determined through inverse kinematics. But in some applications it is important to follow a specified mobile platform trajectory. The main focus of this work is to determine the inverse kinematics of a mobile manipulator to follow the specified end-effector and mobile platform trajectories, especially when both trajectories cannot be exactly followed simultaneously due to physical limitations. Two new control algorithms are developed to solve this problem. In the first control algorithm, three joint-dependent control variables (spherical coordinates D, α and β) are introduced to define the mobile platform trajectory in relation to the end-effector trajectory and vice versa. This allows direct control of the mobile platform motion relative to the end-effector. Singularity-robust and task-priority inverse kinematics with gradient projection method is used to find best possible least-square solutions for the dual-trajectory tracking while maximizing the whole system manipulability. MATLAB Simulated Planar Mobile Manipulation is used to test and optimize the proposed control system. The results demonstrate the effectiveness of the control system in following the two trajectories as much as possible while optimizing the whole system manipulability measure. The second new inverse kinematics algorithm is introduced when the mobile platform motion is restricted to stay on a specified virtual or physical track.

Download or read book Wheeled Mobile Robot Control written by Nardênio Almeida Martins and published by Springer Nature. This book was released on 2021-08-12 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the development and methodologies of trajectory control of differential-drive wheeled nonholonomic mobile robots. The methodologies are based on kinematic models (posture and configuration) and dynamic models, both subject to uncertainties and/or disturbances. The control designs are developed in rectangular coordinates obtained from the first-order sliding mode control in combination with the use of soft computing techniques, such as fuzzy logic and artificial neural networks. Control laws, as well as online learning and adaptation laws, are obtained using the stability analysis for both the developed kinematic and dynamic controllers, based on Lyapunov’s stability theory. An extension to the formation control with multiple differential-drive wheeled nonholonomic mobile robots in trajectory tracking tasks is also provided. Results of simulations and experiments are presented to verify the effectiveness of the proposed control strategies for trajectory tracking situations, considering the parameters of an industrial and a research differential-drive wheeled nonholonomic mobile robot, the PowerBot. Supplementary materials such as source codes and scripts for simulation and visualization of results are made available with the book.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, control of a mobile manipulator system with a calibrated stereo rig is presented. Autonomous mobile manipulator equipped with a vision based target monitoring system can find and track a moving target and also manipulate it. The vision system is utilized to obtain task space feedback for mobile manipulator control. Using vision data, mobile platform (base) and manipulator are controlled with a hybrid visual servo controller and dynamic look and move methodology, respectively. This work also introduces a methodology concerning how the positioning error can be distributed between two mechanical subsystems: base and manipulator. In general these two systems have some degrees of freedom, which correspond to a task space motion capability in the same axis.
