  1. 1. A personalized quasi-passive ankleexoskeleton using human-in-the loop optimization approaches

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

    Author : Ho Ming Kong; [2023]
    Keywords : ;

    Abstract : Passive ankle exoskeletons have been proven to successfully decrease muscle demand for walking. The movement of the user’s ankle drives a mechanical clutch and spring, which eventually stores and returns mechanical energy to the user. READ MORE

  2. 2. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

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

    Author : Jesper Jansson; Wilhelm Nordgren; [2023]
    Keywords : Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Abstract : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

  3. 3. Method to statistically secure field test results for rock drilling tools

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Frida Olander; [2023]
    Keywords : Statistics; Probability; Hypothesis test; Linear regression;

    Abstract : The aim of this project is to find a statistical method that describes survival and outcome of a prototype drilling tool from several references and determine how many references are needed for a statistically secure result. The project also answers which variables that affects the outcome. READ MORE

  4. 4. Anomaly Detection for Condition Monitoring in Robot Systems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Mingjie Huang; [2023]
    Keywords : ;

    Abstract : This thesis addresses the detection of wear patterns in robot joints as an indication of the increase in wear level or impending failures. The main challenges include identifying key wear features, developing efficient anomaly detection algorithms, ensuring generalization across different joints and operating conditions, and enabling real-time monitoring.

  5. 5. Sensorless Hybrid Field-Oriented Control Two-Phase Stepper Motor Driver

    University essay from Linköpings universitet/Reglerteknik

    Author : Emil Lydell; [2023]
    Keywords : Stepper motor; Field-Oriented Control; FOC; Driver; Two-Phase; 2-Phase;

    Abstract : Hybrid stepper motors are small electrical motors with high torque production, compared with other electrical motors of the same size. Hybrid stepper motors are reliable in open-loop systems, in Sinusoidal mode, but with a drawback of high power consumption. READ MORE
