  2. 1. Principles for planning and analyzing motions of underactuated mechanical systems and redundant manipulators

    Author : Uwe Mettin; Anton Shiriaev; Alin Albu-Schäffer; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motion Planning; Underactuated Mechanical Systems; Redundant Manipulators; Virtual Holonomic Constraints; Orbital Stabilization; Human Movement; Walking Robots; Hydraulic Manipulators; Electrical engineering; Elektroteknik; Automatic Control; reglerteknik;

    Abstract : Motion planning and control synthesis are challenging problems for underactuated mechanical systems due to the presence of passive (non-actuated) degrees of freedom. For those systems that are additionally not feedback linearizable and with unstable internal dynamics there are no generic methods for planning trajectories and their feedback stabilization.

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

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

    Abstract : 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. READ MORE

  5. 3. Virtual Holonomic Constraints: from academic to industrial applications
