  1. 1. Agile robotic arm for vertical applications - Evaluation, design and development

    Master-uppsats, Lunds universitet/Maskinelement

    Författare :Rasmus Gren; [2023]
    Nyckelord :Robotic arm development; HKM; Kinematics; Product development; Technology and Engineering;

    Sammanfattning : Existing pick and place robots are either heavy or have a limited workspace for vertical operations. Since there is no robot today that are both light and have a good vertical workspace, this leads to a gap in the market. LÄS MER

  3. 2. The Influence of Electric Currents on Performance of Grease Lubricated Rolling Element Bearings

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Bharath Chanamolu; [2022]
    Nyckelord :Angular contact bearings; Bearing currents; Shaft voltages; Film thickness estimation; Electrical-capacitance method; Frictional moment measurements; Lubricant starvation; Vinkelkontaktlager; Lagerströmmar; Axelspänningar; Filmtjockleksuppskattning; Elektrisk-kapacitansmetod; Friktionsmomentmätningar; Smörjmedelsvält..;

    Sammanfattning : The technological advancement in electrical machinery represents the need to understand the lubricant behaviour in the electrical environment. As shaft voltages are unavoidable in electrical machinery, developing new grease formulations and studying their performance against electric loads is required. LÄS MER

  4. 3. Elbow Design, Servo Motor Selection and Control Implementation of the Agile Parallel Kinematic Manipulator

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Hampus Farmängen; Felix Lundblad; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The purpose of this work was to contribute to the creation of a prototype of a new type of robot called Agile Parallel Kinematic Manipulator or AgilePKM for short. Designing, building and controlling a new type of robot is a task which goes beyond the scope of any master thesis project, but there are subtasks which are more suitable to handle within the available time frame.

  5. 4. Evaluation of Journal Bearings in Manual Transmissions

    Master-uppsats, Maskinkonstruktion; Institutionen för ekonomisk och industriell utveckling

    Författare :Joachim Vidar; Jonas Mellstedt; [2009]
    Nyckelord :journal bearing; manual transmission; efficiency; wear; gearbox;

    Sammanfattning : This thesis work is an evaluation of journal bearings in manual transmissions in automobiles. Today both journal- and needle bearings can be positioned into the gearboxes and in order to reduce the power loss developed by friction when a relative angular velocity arises, the right type of bearing must be chosen.
