  1. 1. Probability Based Path Planning of Unmanned Ground Vehicles for Autonomous Surveillance : Through World Decomposition and Modelling of Target Distribution

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Per Liljeström; [2022]
    Nyckelord :Probability based path planning; Unmanned ground vehicles; UGV; Autonomous surveillance; Cell decomposition; Spatial partitioning; Target distribution modeling; Decay function; Last-seen function; Stochastic processes; Markov chain; Markov process; Markov planner;

    Sammanfattning : The interest in autonomous surveillance has increased due to advances in autonomous systems and sensor theory. This thesis is a preliminary study of the cooperation between UGVs and stationary sensors when monitoring a dedicated area. The primary focus is the path planning of a UGV for different initial intrusion alarms. Cell decomposition, i. LÄS MER

  3. 2. Data-Driven Motion Planning : With Application for Heavy Duty Vehicles

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

    Författare :Oscar Palfelt; [2022]
    Nyckelord :Motion planning; Deep learning; Autonomous driving; Nonuniform sampling; Rörelseplanering; Djupinlärning; Autonom körning; Ojämn provtagning;

    Sammanfattning : Motion planning consists of finding a feasible path of an object between an initial state and a goal state, and commonly constitutes a sub-system of a larger autonomous system. Motion planners that utilize sampling-based algorithms create an implicit representation of the search space via sampling said search space. LÄS MER

  4. 3. Autonomous UAV Path Planning using RSS signals in Search and Rescue Operations

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Axel Anhammer; Hugo Lundeberg; [2022]
    Nyckelord :UAV; DQN; Deep Q Network; particle filter; point mass filter; MDP; POMDP; Markov decision process; partially observable Markov decision process;

    Sammanfattning : Unmanned aerial vehicles (UAVs) have emerged as a promising technology in search and rescue operations (SAR). UAVs have the ability to provide more timely localization, thus decreasing the crucial duration of SAR operations. LÄS MER

  5. 4. OTDOA-Based Positioning in Narrowband IoT

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Axel Berg; [2017]
    Nyckelord :IoT NB-IoT OTDOA Positioning; Technology and Engineering;

    Sammanfattning : This thesis considers the problem of improving the performance of observed time difference of arrival (OTDOA) based positioning for Narrowband Internet of Things (NB-IoT). A new iterative low-complexity algorithm based on expectation maximization successive interference cancellation (EM-SIC) is presented. LÄS MER
