  1. 1. Movement Estimation with SLAM through Multimodal Sensor Fusion

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Jimmy Cedervall Lamin; [2024]
    Keywords : slam; discrete-slam; continuous-slam; synchronous; asynchronous; computer vision; BRISK; opencv; ceres; visual; inertial; sensor fusion; multimodal; Simultaneous Localization and Mapping; time offset; pose estimation; quaternions; movement estimation;

    Abstract : In the field of robotics and self-navigation, Simultaneous Localization and Mapping (SLAM) is a technique crucial for estimating poses while concurrently creating a map of the environment. Robotics applications often rely on various sensors for pose estimation, including cameras, inertial measurement units (IMUs), and more. READ MORE

  3. 2. Vibrations in a high frequency clt floor panel - Measurement, prediction and evaluation

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : André Wirthig; [2023]
    Keywords : Vibrations; High frequency floors; Sensitive equipment; Technology and Engineering;

    Abstract : There is an increased need for floors that can accommodate different type of sensitive equipment [1]. Further, it is recommended to design these floors as high frequency floors (HFF) to be able to meet the stringent vibration criteria [1]. READ MORE

  4. 3. Smart Scooter : Solving e-scooter safety problems with multi-modal, privacy-preserving sensor technology and machine learning

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

    Author : Beatrice Lovely; [2022]
    Keywords : Smart Devices; Machine Learning; Sensors; Radar; Inertial Measurement Unit; Computer Vision; Smarta Saker; Maskininlärning; Sensorer; Radar; Tröghetsmåttenhet; Dator- seende;

    Abstract : Micromobility ride-share scooters (e-scooters) have become a popular mode of transport in several major cities around the world, yet several safety and accessibility issues stem from how these scooters are operated, including sidewalk riding, unsafe parking and wrong-way riding. This thesis tackles these issues through a novel, privacy-preserving, end-to-end sensor system that employs lightweight machine learning models to provide real-time feedback to users to present unsafe scooter operation.

  5. 4. Estimation of Input Forces on a Cutting Tool using Strain Output Signals

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Ram Pradip Mahato; Jiacheng Ma; [2022]
    Keywords : Lathe tool; Multiple sensor signals; Modal analysis; Input force calculation; embedded sensor force; MATLAB;

    Abstract : Lathes are frequently used in industrial production. It is an important parameter to calculate the force exerted by the cutter head on the raw material. Knowing the force acting on the cutting tool will aid in predicting the displacement of the cutting edge as well as predict displacement of the workpiece. READ MORE

  6. 5. Predicting Location-Dependent Structural Dynamics Using Machine Learning

    University essay from KTH/Industriell produktion

    Author : Markus Zink; [2022]
    Keywords : machine learning; artificial intelligence; gradient boosting; LightGBM; multilayer perceptron; prediction; chatter; vibration; structural dynamics; modal parameters; machine tool; tool centre point; work envelope;

    Abstract : Machining chatter is an undesirable phenomenon of material removal processes and hardly to control or avoid. Its occurrence and extent essentially depend onthe kinematic, which alters with the position of the Tool Centre Point, of the machine tool. READ MORE
