Our work has been focused on developing a methodology for process control of bulk deformation-specifically, extrusion. A process model is required for control. The difficulties with currently available models are stated. An appropriate decomposition and associated assumptions are introduced, permitting construction a real-time process model via spectral approximation to solve the axi-symmetric, 2D transient heat conduction equation with heat generation and loss. This solution, simulation results, and model execution times are provided.

American Control Conference (ACC)

The passivity property of dissipative mechanical structures has long been exploited in designing passive controllers that provide robust stability even in the presence of unmodeled dynamics of the system. For an input/output map of a flexible structure to be passive, collocation of the actuators and sensors is required and also the sensors should measure the velocity of the system. The so-called smart structures frequently have more sensors than actuators. Therefore, the passive controller can at best utilize only a subset of the sensors. In this paper we consider the design of a squaring down matrix which would render a system passive subject to some additional performance considerations. The problem of obtaining the synthesized passive output is cast as a set of linear matrix inequalities (LMIs) which can be efficiently solved by the LMI Toolbox in Matlab. We apply this procedure with the assumption that the sensors provide both displacement and velocity information which is generally not true. We show that the passive controllers can be implemented without the use of velocity information. By using synthesized passive outputs in addition to naturally occurring passive outputs, we obtain better system performance. We present experimental results involving a single flexible beam with torque input and hub angular position and strain gage outputs.

IEEE International Symposium on Industrial Electronics (ISIE)

作者： R. Araujo U. Nunes A.T. de Almeida Institute of Systems and Robotics (ISR) Electrical Engineering Department University of Coimbra Coimbra Portugal

Humans perform many tasks with relative ease. In spite of this, many tasks are difficult to model explicitly and it is difficult to design and program automatic control algorithms for them. The development, improvement, and application of learning techniques taking advantage of sensory information would enable the acquisition of new robot skills and avoid some of the difficulties of explicit programming. This paper describes an approach for the generation of skills for the control of multidegree of freedom robotic systems. In the method, the acquisition of skills is done online by self-learning. Instead of generating skills by explicit programming of a perception to action mapping, they are generated by trial and error learning, guided by a performance evaluation feedback function. The structure of the controller consists of two fuzzy subsystems both implemented by feedforward multilayer neural networks. The action fuzzy subsystem has the purpose of generating command actions for the system under control. The evaluation-prediction fuzzy subsystem predicts the future value, a function that evaluates the performance of the controller. Simulation results concerning the application of the approach to learning a robot manipulator force control skill are presented.

International Conference on Pattern Recognition

作者： J. Batista H. Araujo A.T. Almeida ISR-Institute of Systems and Robotics-Department of Electrical Engineering University of Coimbra Coimbra Portugal

The main purpose of this paper is not to present a new camera calibration algorithm or a new pose estimation method, but just to analyse the stability of the camera pose estimation using the Haralick observation which is based on the fact that there is sufficient information on the 2D perspective projection of a rectangle of unknown size in 3D space to determine the three camera look angles. A brief description of the camera look angles computation is presented and a model for the expected stability of the camera look angles computation front noisy image data is described. A stability analysis as a function of the pose of the camera is also described, and the influence of the camera pose is confirmed with simulated data. As a result, camera pose view strategies for accurate camera orientation computation can be extracted from this pose view stability analysis.

International Conference on Multisensor Fusion and Integration for Intelligent systems (MFI)

作者： J. Batista P. Peixoto H. Araujo ISR-Institute of Systems and Robotics Department of Electrical Engineering University of Coimbra Coimbra Portugal

An active vision system has to enable the implementation of reactive visual processes and of elementary visual behaviors in real time. In this paper we describe the real-time implementation of several visual behaviors in an active vision system. Issues related to the real-time implementation are discussed, namely in what concerns the modelling of the measurements made in the image. Even though in most applications a fully calibrated system is not required, we also describe a methodology for calibrating the camera head, taking advantage of its degrees of freedom. These calibration parameters are used to evaluate the performance of the system. Another important issue of the operation of active vision binocular heads is their integration into more complex robotic systems. We claim that higher levels of autonomy and integration can be obtained by designing the system architecture based on the concept of purposive behavior. At the lower levels we consider vision as a sensor and integrate it in control systems (both feedforward and servo loops) and several visual processes are implemented in parallel, computing relevant measures for the control process. At higher levels the architecture is modeled as a state transition system. Finally we show how this architecture can be used to implement a pursuit behavior using optical flow. Simultaneously vergence control can also be performed using the same visual processes.

An active vision system has to enable the implementation of reactive visual processes and of elementary visual behaviors in real time. Therefore the control architecture is extremely important. In this paper we discuss a number of issues related with the implementation of a real-time control architecture and describe the architecture we are using with our "binocular heads". Another important issue of the operation of active vision binocular heads is their integration into more complex robotic systems. We claim that higher levels of autonomy and integration can be obtained by designing the system architecture based on the concept of purposive behavior. Finally we describe a system where the integration of an active vision stereo head in a mobile robot has been performed, with real-time performance.

IEEE International Workshop on Intelligent Robots and systems (IROS)

作者： G.J. Hamlin A.C. Sanderson Center for Advanced Technology in Automation Robotics and Manufacturing and Department of Electrical Computer and Systems Engineering Rensselaer Polytechnic Institute Troy NY USA

TETROBOT is a modular system for the design, implementation, and control of a class of highly redundant parallel robotic mechanisms. This paper describes new experimental results based on evaluation of prototype configurations with up to 18 nodes, 48 links and 15 actuators. TETROBOT is an actuated robotic structure which may be reassembled into many different configurations while still being controlled by the same hardware and software architecture. Implementations of a double octahedral platform, a tetrahedral arm and a six-legged walker, constructed from the same set of parts, are described. The TETROBOT system addresses the needs of application domains, such as space, undersea, mining, and construction, where adaptation to unstructured and changing environments and custom design for rapid implementation are required.

Parallel robots can be built by linking together unit cells in configurations which retain the static determinacy of the overall structure. In the Tetrobot system, the kinematics of these concatenated structures can be solved by propagation of solutions through connected graphs of linked modules. In this paper, we examine the synthesis of unit cells which could be used in creating these structures and retain the ability to compute the kinematics for control of the actuated system. Admissible unit cells are shown to form families in two- and three-dimensions, and a set of synthesis rules is described which generates the members of these families recursively for each generations. The resulting set of modules comprises a broad set of useful cells which can be used to design parallel robots and guarantee the computability of their kinematics on a cell-by-cell basis.

IEEE International Conference on robotics and Automation (ICRA)

作者： R. Joshi A.C. Sanderson NYS Center for Advanced Technology in Automation Robotics and Manufacturing and Electrical Computer and Systems Engineering Department Rensselaer Polytechnic Institute Troy NY USA

This paper presents an application of feature-based visual servoing to achieve accurate and robust 3D filament alignment. Two orthogonal cameras are used to localize the five degrees of freedom of an axi-symmetric filament. An algorithm for precisely estimating the center and orientation features of a filament in a camera view is described. The use of feature-based servoing overcomes the difficulty of 3D camera calibration in a factory environment. These features drive a PID control loop for each view. The two views are coupled in one degree of freedom, and the multiple-view controller switches between two single-view controllers to achieve 3D servoing. The overall accuracy achieved is in thousandths of an inch. Experimental results on the performance of the control algorithm are discussed. Models explaining the system behavior are presented. The use of visual servoing in this application far exceeds the positioning accuracy and the repeatability of human operators.
