  1. 16. Semi-Automating Forestry Machines : Motion Planning, System Integration, and Human-Machine Interaction

    Författare :Simon Westerberg; Anton S. Shiriaev; Klas Nilsson; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry Robotics; Forest Machine Automation; Trajectory Planning; Hydraulic Manipulators; Teleoperation; Virtual Environments; Interaction Methods; Head Tracking;

    Sammanfattning : The process of forest harvesting is highly mechanized in most industrialized countries, with felling and processing of trees performed by technologically advanced forestry machines. However, the maneuvering of the vehicles through the forest as well as the control of the on-board hydraulic boom crane is currently performed through continuous manual operation. LÄS MER

  3. 17. Topics in Machining with Industrial Robot Manipulators and Optimal Motion Control

    Författare :Björn Olofsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Two main topics are considered in this thesis: Machining with industrial robot manipulators and optimal motion control of robots and vehicles. The motivation for research on the first subject is the need for flexible and accurate production processes employing industrial robots as their main component. LÄS MER

  4. 18. High-Speed Vision and Force Feedback for Motion-Controlled Industrial Manipulators

    Sammanfattning : Over the last decades, both force sensors and cameras have emerged as useful sensors for different applications in robotics. This thesis considers a number of dynamic visual tracking and control problems, as well as the integration of these techniques with contact force control. LÄS MER

  5. 19. Time-Optimal Cooperative Path Tracking for Multi-Robot Systems

    Författare :Hamed Haghshenas; Anders Hansson; Mikael Norrlöf; Anders Robertsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Robotic systems are nowadays the key technology in a wide variety of applications. The increasing demand for performance of robotic systems is often met by employing a team of cooperating robots for a specific task. LÄS MER

  7. 20. Towards Manipulator Learning by Demonstration and Reinforcement Learning

    Författare :Alexander Skoglund; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Manipulation; learning; robot learning from demonstration; programming by demonstration; imitation in robotics.; Computer science; Datavetenskap;

    Sammanfattning : This thesis address how robotic arms, called manipulators, can learn a task demonstrated by a teacher. The concept of showing a robot a task, instead of manually programming it, is appealing since it makes it easier to instruct robots. LÄS MER
