  2. 1. Formations and Obstacle Avoidance in Mobile Robot Control

    Author : Petter Ögren; KTH; []
    Keywords : Mobile Robots; Robot Control; Obstacle Avoidance; Multi-robot system; Formation Control; Navigation Function; Lyapunov Function; Model Predictive Control; Receding Horizon Control; Gradient Climbing; Gradient Estimation.;

    Abstract : This thesis consists of four independent papers concerningthe control of mobile robots in the context of obstacleavoidance and formation keeping. The first paper describes a new theoreticallyv erifiableapproach to obstacle avoidance. READ MORE

  4. 2. Improving Fixed Wing UAV Endurance, by Cooperative Autonomous Soaring

    Author : Olov Andersson; Patrick Doherty; Mattias Villani; Petter Ögren; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Symbicloud; ELLIIT; WASP;

    Abstract : Robots are increasingly expected to go beyond controlled environments in laboratories and factories, to enter real-world public spaces and homes. However, robot behavior is still usually engineered for narrowly defined scenarios. READ MORE

  6. 4. On Informative Path Planning for Tracking and Surveillance

    Author : Per Boström-Rost; Gustaf Hendeby; Daniel Axehill; Petter Ögren; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis studies a class of sensor management problems called informative path planning (IPP). Sensor management refers to the problem of optimizing control inputs for sensor systems in dynamic environments in order to achieve operational objectives. READ MORE

  7. 5. Improving Manipulation and Control of Search and Rescue UGVs Operating Across Autonomy Levels

    Author : Fredrik Båberg; Petter Ögren; Paolo Robuffo Giordano; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datalogi; Computer Science;

    Abstract : Robots are often used for “dirty, dull and dangerous” jobs, where time, money or lives can be saved. A field with dangerous situations is search and rescue, with structural collapses and toxic environment. In those situations, robots have the potential to save lives. READ MORE
