Nonholonomic path planning with inequality constraints

Nonholonomic path planning with inequality constraints

引用

IEEE International Conference on robotics and Automation (ICRA)

作者： A.W. Divelbiss J. Wen New York State Center for Advanced Technology in Robotics and Automation and Department of Electrical Computer and Systems Engineering Rensselaer Polytechnic Institute Troy NY USA

This paper presents an algorithm for finding a kinematically feasible path which satisfies a given set of nonholonomic constraints while enforcing both equality and inequality constraints on the configuration vector. The path planning problem is transformed from a finite time nonlinear control problem into a static root finding problem which is iteratively solved. By using an exterior penalty function method, the constrained root finding problem is converted to an unconstrained problem. Convergence of the algorithm depends upon a certain gradient operator being full rank. It has recently been shown that, in the absence of any configuration inequality constraints, the full rank condition is generic. In this paper, we show the full rank condition for a special inequality constraint case. An experiment in which the algorithm is applied to an actual double tractor-trailer vehicle is presented.< >

IEEE International Conference on robotics and Automation (ICRA)

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

A general approach to model-based multisensor data fusion using a minimal representation size criterion is described. Each sensor is modeled by a general constraint equation which defines a data constraint manifold (DCM), and observed sensor data populate the measurement space according to these constraints. The choice of multisensor interpretations is based on a minimal representation size criterion which evaluates the complexity through correspondence and encoded errors weighted by relative sensor accuracy and precision. This general framework automatically selects subsets of data features called constraining data feature sets (CDFS) and chooses the CDFS corresponding to a minimal representation interpretation of the observed data. The resulting procedure fuses heterogeneous sensor readings into a single estimation method. The method is illustrated for a visual and tactile data fusion example. The approach generalizes to problems with non-geometric models, and can be used for multisensor system identification in other domains such as process control.< >

Robot 3D force-based surface-tracking

Robot 3D force-based surface-tracking

International Conference on Industrial Electronics, Control and Instrumentation

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

The problem of control of a robot manipulator performing compliant tasks is addressed. The force and position control is based on the Smith predictor design. For the overall control we are pursuing a behaviour-based architecture approach. The paper describes a 3D surface tracking behaviour controller. The tracking operation is performed in real-time using contact force feedback. Surface tracking is an important operation for self-teaching and exploratory tasks in unknown environments. It can be seen as a first step to the more general and important problem of surface following in contact. A method for tool tip contact frame calibration is presented. Results of simulations and real-time implementation are presented and discussed.< >

IEEE Computer Society Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)

作者： Joarder Raviv Robotics Center and Department of Electrical Engineering Florida Atlantic University Boca Raton FL USA Robot Systems Division National Institute for Standards and Technology Gaithersburg MD USA

The concept of visual looming can be used as a powerful visual cue for autonomous obstacle avoidance. In this paper a method that measures looming quantitatively by fixating a camera at a point on the surface of an object is presented. It is based on studying the texture and its temporal change near the fixation point. The surface may be tilted relative to the optical axis. Looming can be calculated from the relative change in texture density and from the local orientation of the surface. The orientation is obtained from a set of one-dimensional directional densities of the texture primitives. This visual cue is used as a feedback signal of a closed loop system to implement obstacle avoidance using a six-degree-of-freedom simulator.< >

A visual-motion fixation invariant

IEEE Computer Society Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)

作者： Raviv Ozery Robotics Center and Department of Electrical Engineering Florida Atlantic University Boca Raton FL USA Robot Systems Division National Institute for Standards and Technology Gaithersburg MD USA Florida Atlantic University Boca Raton FL US Robotics Center Florida Atlantic Univ. Boca Raton FL USA

The paper deals with a visual-motion fixation invariant. We show that during fixation there is a measurable nonlinear function of optical flow that produces the same value for all points of a stationary environment, regardless of the 3D shape of the environment. During fixated camera motion relative to a rigid object, e.g., a stationary environment, the projection of the fixated point remains (by definition) at the same location in the image, and all other points located on the 3D rigid object can only rotate relative to the 3D fixation point. This rotation rate of the points is invariant for all points that lie on the particular environment, and it is measurable from a sequence of images. This new invariant is obtained from a set of monocular images, and is expressed explicitly as a closed form solution. We show how to extract this invariant analytically from a sequence of images using optical flow information, and we present results obtained from real data experiments.< >

International Conference on Industrial Electronics, Control and Instrumentation

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

Adaptive-control experiments with the PUMA 560 robot manipulator are addressed. We analyse the effectiveness of the application of robust indirect adaptive-control schemes in controlling the force-position of a robot manipulator in the task coordinates system. The adaptive control scheme comprises a modified recursive least squares (MRLS) parameter estimation algorithm and a pole-placement controller. Results of real-time implementations are presented and discussed.< >

Improved Al/InP Schottky barriers by coimplantation of Be/P

Indium Phosphide and Related Materials Conference

作者： R. Tyagi T.P. Chow J.M. Borrego K.A. Pisarczyk Center for Integrated Electronics and Department of Electrical Computers and Systems Engineering Rensselaer Polytechnic Institute Troy NY USA

The development of conventional InP MESFET technology is strongly hampered by the low barrier height (0.3-0.4eV) obtained in InP, due to surface Fermi level pinning, and consequent high reverse leakage currents. As a result, several techniques are being applied to increase the Schottky barrier height on n-InP. The authors present a technique for obtaining improved Al/InP Schottky barriers on n-InP by using coimplantation of Be/P. Schottky barrier heights as high as 0.64 eV have been obtained, along with an ideality factor very close to unity. The reverse leakage current density is also reduced by almost four orders of magnitude.< >

International Symposium on Power Semiconductor Devices and Ics (ISPSD)

作者： T.P. Chow R. Tyagi Center for Integrated Electronics and Department of Electrical Computers and Systems Engineering Rensselaer Polytechnic Institute Troy NY USA

A critical evaluation of the performance capabilities of various wide-bandgap compound semiconductors for superior high-power and high-frequency unipolar electronic devices is presented. A wide range of semiconductors, including the III-V and II-VI compounds, various semiconducting oxides, and some pseudobinary intermetallic compounds, have been analyzed. In order to cover all possible features of power device performance, seven different figures of merit are evaluated for the various semiconductors. Besides diamond and SiC, it is found that AlN, GaN, ZnO, and the intermetallic compounds Ga/sub x/In/sub 1-x/N, Al/sub x/In/sub 1-x/N, Al/sub x/Ga/sub 1-x/N, and (AlN)/sub x/(SiC)/sub 1-x/ offer significantly improved unipolar power device performance over Si.< >

作者： Y.C. Kim K. Price Institute for Robotics and Intelligent Systems Departments of Computer Science and Electrical Engineering University of Southern California Los Angeles CA USA

The issues of using errorful data in motion estimation and of using feedback to improve feature extraction and matching in incremental analysis are addressed. Initial noisy correspondence data are continously refined by removing those parts that do not fit the estimated 3-D motion parameters. The extraction of a tracked region is guided by its expected properties obtained from the corresponding objects in the previous frames. The surfaces of objects are reconstructed from a sparse depth map.< >

IEEE International Conference on robotics and Automation (ICRA)

作者： A. Glatzl S.H. Murphy J.T. Wen P. Kopacek Institute for Handling Devices and Robotics University of Technology Vienna Austria Electrical Computer and Systems Engineering Department Rensselaer Polytechnic Institute Troy NY USA

It is shown, by both theoretical argument and experimentation, that sliding control with a boundary layer does not outperform proportional-derivative (PD) control due to the fact that the gain in the boundary layer cannot exceed the PD gain due to noise and discretization. A combined switching and PD control is proposed with the level of switching selected so that the position error is reduced but is slightly higher than the noise level in order that chattering will not occur. The switching level can be further adaptively updated based on the position error level. Through extensive experimentation of a six-degrees-of-freedom (DOF) arm, it is shown that the proposed controllers avoid chattering and reduce the transient and steady state position errors of the PD control alone.< >
