  1. 1. Terrain machine learning

    Author : Viktor Wiberg; Martin Servin; Tomas Nordfjell; Eddie Wadbro; Todor Stoyanov; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multibody dynamics simulation; rough terrain vehicle; autonomous vehicles; robotics control; discrete element method; sim-to-real; reinforcement learning; fysik; Physics;

    Abstract : The use of heavy vehicles in rough terrain is vital in the industry but has negative implications for the climate and ecosystem. In addition, the demand for improved efficiency underscores the need to enhance these vehicles' navigation capabilities. READ MORE

  2. 2. Automation in forestry : development of unmanned forwarders

    Author : Ola Ringdahl; Thomas Hellström; Tomas Nordfjell; Arto Visala; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Computer science; Datavetenskap; Forest engineering; Skogsteknik; computer and systems sciences; data- och systemvetenskap;

    Abstract : For the last 50 year, forestry operations have become more and more mechanized. In modern forestry in Europe two machines are typically used; a harvester that fells, debranches and cross-cuts the trees into logs and a forwarder that transports them to the nearest road. READ MORE

  3. 3. 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

  4. 4. A Methodology for Automation of Mechanized Forest Regeneration

    Author : Håkan Lideskog; Magnus Karlberg; Dan Bergström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Abstract : High quality forest regeneration is typically performed by a combination of site preparation through mounding and deep planting. These operations are performed either by mounders with subsequent manual planting, or by mechanized tree planting devices that creates mounds and, simultaneously, plant seedlings. READ MORE

  5. 5. Object Identification for Autonomous Forest Operations

    Author : Songyu Li; Magnus Karlberg; Ulf Bodin; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Maskinkonstruktion; Machine Design;

    Abstract : The need to further unlock productivity of forestry operations urges the increase of forestry automation. Many essential operations in forest production, such as harvesting, forwarding, planting, etc. READ MORE
