    Sammanfattning : Today’s electric excavators uses standard hydraulics to control external tools. To increase the degree of freedom the excavator is equipped with a tiltrotator placed between arm and bucket. LÄS MER

  3. 2. Reaction Wheel Control System for a Self-balancing Bike : Reaction wheel based control mechanism for a small scale prototype bike

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

    Författare :Reman Soryani; [2023]
    Nyckelord :Mechatronics; Control Theory; Reaction Wheel; PID Controller; Robotics; Mekatronik; Reglerteknik; Mekanik; PID reglering; Robotik;

    Sammanfattning : In this thesis, the design of a self balancing prototype bike with a reaction wheel as balancing mechanism will be investigated. Bikes are inherently unstable systems, that dynamically resemble an inverted pendulum at a stand still. LÄS MER

  4. 3. Assessment of Shoulder Biomechanics during Pull-up Techniques

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Mariah Sabioni; [2023]

    Sammanfattning : CrossFit® has gained popularity as a functional training method that caters to individuals with varying levels of fitness, including those with little to no athletic background. Regardless, shoulders represent the highest injury rate in this sport, most frequently associated with pull-up variations. LÄS MER

  5. 4. Size effect in wood : Characterization of mechanical properties using digital image correlation method

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

    Författare :Amir Saeidi; Olafur Johannsson; [2023]
    Nyckelord :compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

    Sammanfattning : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. LÄS MER

  7. 5. A Mechatronic Jar Opener : A Design Study of a Motorized Home Appliance for Improved Accessibility

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

    Författare :Charlotte Paulson Ramel; Sofia Mobrin; [2023]
    Nyckelord :Mechatronics; Improved accessibility; Torque; Planetary Gear; Arduino; Motorized Home Appliance.; Mekatronik; Förbättrad tillgänglighet; Vridmoment; Planetväxel; Arduino; Hemelektronik.;

    Sammanfattning : Mechatronics is a rapidly growing field that combines elements of mechanical, electrical, and software engineering to design and develop intelligent systems. One area where mechatronics still has the potential to have a significant impact is personal appliances and aids for people with disabilities, which this report aims to explore. LÄS MER
