  1. 1. Mobile Robot Traversability Mapping : For Outdoor Navigation

    Författare :Peter Nordin; Petter Krus; Jonas Nygårds; Nils Axel Andersen; Linköpings universitet; []
    Nyckelord :Traversability; Laser; Roughness; Mapping; Planning; Mobile robot; Navigation; Implementation;

    Sammanfattning : To avoid getting stuck or causing damage to a vehicle or its surroundings a driver must be able to identify obstacles and adapt speed to ground conditions. An automatically controlled vehicle must be able to handle these identifications and adjustments by itself using sensors, actuators and control software. LÄS MER

  3. 2. Towards Enabling Exploration of Planetary Subterranean Environments using Unmanned Aerial Vehicles

    Författare :Akash Patel; George Nikolakopoulos; Savvas Loizou; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

    Sammanfattning : This thesis presents a novel navigation framework established to enable the exploration of planetary subterranean areas with Unmanned Aerial Vehicles (UAVs). The key contributions of this thesis work form a robot-safe rapid navigation framework that utilizes a novel bifurcating frontier-based exploration approach. LÄS MER

  4. 3. Repeated Path Planning for Mobile Robots in Dynamic Environments

    Författare :Maarja Kruusmaa; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision-making; mobile robot; case-based reasoning; navigation; dynamic environments; path planning;

    Sammanfattning : This thesis presents a global navigation strategy for repeated traverse of mobile robots in dynamic environments. The research is motivated by the fact that most real-world applications of mobile robotics imply repeated traverse between predefined target points in large, uncertain real-world domains. LÄS MER

  5. 4. Terrain machine learning

    Författare :Viktor Wiberg; Martin Servin; Tomas Nordfjell; Eddie Wadbro; Todor Stoyanov; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; multibody dynamics simulation; rough terrain vehicle; autonomous vehicles; robotics control; discrete element method; sim-to-real; reinforcement learning; fysik; Physics;

    Sammanfattning : The use of heavy vehicles in rough terrain is vital in the industry but has negative implications for the climate and ecosystem. In addition, the demand for improved efficiency underscores the need to enhance these vehicles' navigation capabilities. LÄS MER
