    Sammanfattning : Forests represent one of the biggest terrestrial ecosystems of Earth, that can produce important raw renewable materials such as wood with the help of sun, air and water. To efficiently extract these raw materials, the tree harvesting process is highly mechanized in developed countries, meaning that advanced forestry machines are continuously used to fell, to process and to transport the logs and biomass obtained from the forests.

  3. 3. Semi-Automating Forestry Machines Motion Planning, System Integration, and Human-Machine Interaction

    Detta är en avhandling från Umeå : Umeå Universitet

    Författare :Simon Westerberg; Umeå universitet.; [2014]
    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

  4. 4. Cooperative Motion and Task Planning Under Temporal Tasks

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Meng Guo; KTH.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Temporal-logic-based languages provide a formal and accurate way to specify complex motion and action missions for autonomous robots, beyond the classic point-to-point navigation task. The first part of the thesis is devoted to the nominal scenario: an autonomous robot is given a motion task specified as Linear-time Temporal Logic (LTL) formulas. LÄS MER
