  1. 1. Learning a Grasp Prediction Model for Forestry Applications

    University essay from Umeå universitet/Institutionen för fysik

    Author : Elias Olofsson; [2024]
    Keywords : Forwarder; Autonomous grasping; Deep learning; Multibody dynamics; Convolutional neural network;

    Abstract : Since the advent of machine learning and machine vision methods, progress has been made in tackling the long-standing research question of autonomous grasping of arbitrary objects using robotic end-effectors. Building on these efforts, we focus on a subset of the general grasping problem concerning the automation of a forwarder. READ MORE

  3. 2. Complexity Analysis and Structural Optimization for Architecture Models of Mechatronic Systems

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Yuanyang Zhang; [2023]
    Keywords : Mechatronic System Design; Architecture Model; DSM; Structural Complexity; Partitioning Optimization Design; Mekatronisk Systemdesign; Arkitektur Modell; DSM; Strukturell Komplexitet; Partitionering Optimering Design;

    Abstract : The design and development of mechatronic system are becoming an increasingly complex task due to the numerous disciplines involved, rapidly increasing scales, and the integration issues of different domains and technologies. The structural complexity of the architecture model design decides the quality of system design in many aspects: the scalability of the system design; usage of allocated resources which influences the computational overhead, etc. READ MORE

  4. 3. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Arvid Söderlund; [2023]
    Keywords : Harvester; Harvester head; Komatsu Forest; Hydraulics; Equalizer bar; Parallellstag; Stag; Skogsmaskin; Skördare; Aggregat; Skog;

    Abstract : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.

  5. 4. Control Method for an Automated Forest Machine Based on Deep Reinforcement Learning

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Youchen Sun; [2023]
    Keywords : ;

    Abstract : An automated forest machine was designed in order to improve the working environment of today’s forest machine operators. In order to realize the autonomous control of the forest machine, model-based methods such as A* and dynamic window were used in previous projects. READ MORE

  6. 5. Hästen i skogsbruket – kommuners erfarenheter

    University essay from SLU/School for Forest Management

    Author : Malin Carlsson; Pernilla Johansson; [2022]
    Keywords : skogshäst; arbetshäst; tätortsnära; skogsvårdsåtgärd; markskador;

    Abstract : Hästarna hade förr en stor betydelse i skogsbruket, då de avlastade människan när det gällde bär- och draghjälp. I början på 1900-talet fanns det cirka 600 000 hästar i Sverige som sedan kom att minska drastiskt efter andra världskriget. READ MORE
