  1. 1. Magnetic field separation for current prediction in three-phase systems : Regression-based current prediction

    University essay from Mälardalens universitet/Akademin för innovation, design och teknik

    Author : Sara Lenman; Sofia Blaad; [2023]
    Keywords : Alternating Current; Crosstalk Separation; Magnetic field sensors; Regression; Sensor technology; Three-phase system;

    Abstract : Current controls the motion of a manipulator. The manipulators at ABB are powered by a three-phase alternating current system where shunt resistors are utilised to measure the current to the motors. Magnetic field sensors are instead investigated to eliminate issues with power losses, the number of components and the cost of the shunt resistors. READ MORE

  3. 2. Experiments with Visual Odometry for Hydrobatic Autonomous Underwater Vehicles

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Somnath Balaji Suresh Kumar; [2023]
    Keywords : Hydrobatic AUVs; VO; Stonefish; ORB-SLAM2; VISO2; Hydrobatiska AUV:er; VO; Stonefish; ORB-SLAM2; VISO2;

    Abstract : Hydrobatic Autonomous Underwater Vehicles (AUVs) are underactuated robots that can perform agile maneuvers in challenging underwater environments with high efficiency in speed and range. The challenge lies in localizing and navigating these AUVs particularly for performing manipulation tasks because common sensors such as GPS become very unreliable underwater due to their poor accuracy.

  4. 3. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Arvin Razavi; [2023]
    Keywords : IMU wrist angle estimation; Wrist absolute angle; IMU-based human motion capture; orientation filter; Complementary filter; Kalman filter; IMU handledsvinkeluppskattning; handleds absolutvinkel; IMU-baserad mänsklig rörelsefångst; orienteringsfilter; komplementfilter; Kalman-filter;

    Abstract : Hand-intensive work is closely related to the prevalence of upper body and hand/wrist work-related musculoskeletal disorders (WMSDs) in office work, manufacturing, service industries, as well as the healthcare industry. Some risk factors include vibrations, forceful exertions, heavy manual handling, repetitive motions, and prolonged nonneutral wrist postures. READ MORE

  5. 4. Introducing disturbances to a chopped PIR sensor when investigating the performance in an office environment

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

    Author : Maria Sandahl; Joel Fröberg; [2023]
    Keywords : ;

    Abstract : This master's thesis, conducted in collaboration with Knowit Connectivity, aims to develop a booking device for meeting rooms. The focus of the project is to identify and mitigate disturbances in the C-PIR sensor introduced by Haili Liu et al. READ MORE

  6. 5. Assessment of Shoulder Biomechanics during Pull-up Techniques

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Mariah Sabioni; [2023]
    Keywords : strength training; biomechanics; motion analysis; shoulder; styrketräning; biomekanik; rörelseanalys; axel;

    Abstract : 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. READ MORE
