  1. 1. Improving Behavior Trees that Use Reinforcement Learning with Control Barrier Functions : Modular, Learned, and Converging Control through Constraining a Learning Agent to Uphold Previously Achieved Sub Goals

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jannik Wagner; [2023]
    Nyckelord :Behavior Trees; Reinforcement Learning; Control Barrier Functions; Robotics; Artificial Intelligence; Verhaltensbäume; Verstärkendes Lernen; Kontrollbarrierefunktionen; Robotik; Künstliche Intelligenz; Beteendeträd; Förstärkningsinlärning; Kontrollbarriärfunktioner; Robotik; Artificiell Intelligens;

    Sammanfattning : This thesis investigates combining learning action nodes in behavior trees with control barrier functions based on the extended active constraint conditions of the nodes and whether the approach improves the performance, in terms of training time and policy quality, compared to a purely learning-based approach. Behavior trees combine several behaviors, called action nodes, into one behavior by switching between them based on the current state. LÄS MER

  3. 3. Design and evaluation of a solid-state LiDAR system : for wireless distance measurements

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och system

    Författare :Christian Hagstedt; Sebastian Jönsson; [2022]
    Nyckelord :Solid-state; LiDAR; Python; Raspberry Pi; Switching regulator; PCB; 3D Printing;

    Sammanfattning : The advent of smarter vehicles coupled with declining costs for solid-state light detection and ranging (LiDAR) sensors unlocks the potential of cheaper devices that experience less mechanical wear while providing smaller form factors. The early state of the market makes evaluating the limited supply of available sensors interesting. LÄS MER
