  1. 1. On Robot Control using Range Sensors : with Special Reference to Active Uncertainty Reduction

    Author : Bernt Nilsson; Aarne Halme; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Robot Gripping and Docking; Gripper-Object Feedback; Non-contact Sensing; Laser Ranging; Flexible Arm; Mobile Robot; Probing; Dual Control; LQG-Feedback;

    Abstract : This thesis addresses the problem of positioning robots relative to objects in the surrounding work space. The object's position and orientation (posture) are measured using a non-contact sensor on-board the robot. For gripping/docking tasks the goal posture is specified relative to the object and not in a fixed coordinate system of the robot. READ MORE

  2. 2. On Robot Feedback from Range Sensors : Reliable Control by Active Reduction of Uncertainty and Ambiguities

    Author : Jonas Nygårds; John Hallam; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot gripping and docking; LQG-feedback; posture estimation; Gaussian sum; optronic sensing; sheet of light range camera; time-of-flight laser; specular reflection s; multiple scattering; range ghosts ; active reduction of ambiguities; reliability; uncertainty; tolerances;

    Abstract : This thesis is on modelling and experimental tests when non contact sensing isused for feedback control in robotics. The motion of the robot is to be controlled relative to objects in the surrounding workspace during operations like gripping/docking, surface following, shape measuring etc. READ MORE

  3. 3. Surface Status Classification, Utilizing Image Sensor Technology and Computer Models

    Author : Patrik Jonsson; Hans-Erik Nilsson; Benny Thörnberg; Jörgen Bogren; Torbjörn Eltoft; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road condition; NIR; infrared; remote sensing; signal processing; classifiers;

    Abstract : There is a great need to develop systems that can continuously provide correct information about road surface status depending on the prevailing weather conditions. This will minimize accidents and optimize transportation. READ MORE

  4. 4. Heterogeneous Integration of Silicon and Printed Electronics for Intelligente Sensing Devices

    Author : Li Xie; Lirong Zheng; Donald Lupo; KTH; []
    Keywords : ;

    Abstract : Driven by the exploding popularity of the Internet-of-Things (IoT), the demand for thin, flexible, lightweight intelligent sensingdevices is growing rapidly. Two attractive examples are intelligent packaging and wearable healthcare monitoring devices, which help to connect and track / monitor everything / everybody at any time and in any place. READ MORE

  5. 5. Low Frequency Acoustic Excitation and Laser Sensing of Vibration as a Tool for Remote Characterization of Thin Sheets

    Author : Etienne Mfoumou; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nondestructive testing; remote acoustics; slow dynamics; nonequilibrium dynamics; resonance frequency; material characterization; vibration-based technique; fracture toughness;

    Abstract : There is a need to monitor the existence and effects of damage in structural materials. Bulk components provide a much publicized example, but the need exists in a variety of other structures, such as layered materials used in food packaging industries. READ MORE
