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

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

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

    Sammanfattning : 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. LÄS MER

  4. 3. Design av en hydraulisk bandspännare

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Nils Forsman; [2023]
    Nyckelord :skogsmaskinsband; skogsmaskin; hydraulik;

    Sammanfattning : Olofsfors AB tillverkar bland annat boggiband för skogsmaskiner. Dessa band kräver en extern spännare vid montering som i dagsläget finns i manuellt och skruvdragardrivet utförande. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Sammanfattning : 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.

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

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Youchen Sun; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
