  1. 16. A comparison of genetic algorithm and reinforcement learning for autonomous driving

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

    Author : Ziyi Xiang; [2019]
    Keywords : Thesis; Machine learning; Genetic algorithm; Deep reinforcement learning; Autonomous driving; Thesis; Maskininlärning; Genetisk algoritm; Djup förstärkning lärande; självkörandebilar;

    Abstract : This paper compares two different methods, reinforcement learning and genetic algorithm for designing autonomous cars’ control system in a dynamic environment. The research problem could be formulated as such: How is the learning efficiency compared between reinforcement learning and genetic algorithm on autonomous navigation through a dynamic environment? In conclusion, the genetic algorithm outperforms the reinforcement learning on mean learning time, despite the fact that the prior shows a large variance, i. READ MORE

  4. 18. Autonomous Docking and Navigation of ships using Model Predictive Control

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

    Author : Mao-Wei Nilsson; [2018]
    Keywords : ;

    Abstract : Autonomous shipping is a coming field, where it will be important tooperate a ship without manual intervention. Although there are manyissues yet to be solved, not the least the legal ones, it would be interestingto investigate functions that already now would be possibleto use in today’s ship operation.

  5. 19. A Path Planning Approach for Context Aware Autonomous UAVs used for Surveying Areas in Developing Regions

    University essay from KTH/Mekatronik

    Author : Fredrika Kringberg; [2018]
    Keywords : Unmanned aerial vehicles; Autonomous vehicles; Area surveying; Navigation; Path planning; Potential field; Object detection;

    Abstract : Developing regions are often characterized by large areas that are poorly reachable or explored. The mapping and census of roaming populations in these areas are often difficult and sporadic. A recent spark in the development of small aerial vehicles has made them the perfect tool to efficiently and accurately monitor these areas. READ MORE

  6. 20. Autonomous Compaction Roller : Temporarily convert a non autonomous compaction machine to become autonomous during endurance testing

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Sebastian Tuma Fischer; Jojje Sundblad; [2018]
    Keywords : Autonomous system; Compaction machine; Endurance testing; Risk assessment; Self-driving; Autonomt system; Kompakteringsmaskin; Långtidsprov; Riskanalys; Självkörande;

    Abstract : How can a non-autonomous compaction roller be converted to become temporarily autonomous while it performs a 500hours endurance test? Particularlysince the compaction rollers in question is not built to be autonomous and shall not be autonomous after the endurance test is completed. The autonomous system shall also be adaptable to all compaction rollers which Dynapac is developing and shall be moved to another machine when the endurance test is completed. READ MORE
