1. 11. Reactive Navigation Methods for Autonomous Robots: Safety, Coordination, and Field Deployment

   Författare :Björn Lindqvist; George Nikolakopoulos; Christoforos Kanellakis; Alberto Bemporad; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Field Robotics; NMPC; Obstacle Avoidance; Collision Avoidance; Multi-agent Systems; Robot Navigation; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

   Sammanfattning : In the new era of intelligent systems, small-scale electronics, and advanced sensors, the application use-cases and operational capabilities of autonomous robots are exponentially increasing. Through their ability to execute complex tasks while relying only on onboard sensors and computation, autonomous field robots are showing promising results in inspection of infrastructure, search-and-rescue or surveillance, maintenance tasks, or in general operations in areas that prove to be dangerous or hazardous for human operators to enter, while also often increasing the efficiency of such tasks.

3. 12. Optimization of Manufacturing Cells Using Discrete Event Models

   Författare :Avenir Kobetski; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Flexible Manufacturing; Optimal Scheduling; Supervisory Control Theory; A*; Velocity Balancing; Discrete Events Systems; Mixed Integer Linear Programming; Timed Deterministic Finite Automata; Robot Coordination; Visibility Graphs;

   Sammanfattning : As the name suggests, this thesis is concerned with flexible manufacturing systems (FMS) and their way of living. More specifically, the main objective of this workis to generate working schedules for the moving objects of the manufacturing cells. LÄS MER

4. 13. Path integral control endowed robot planning under spatiotemporal logic specifications

   Författare :Péter Várnai; Dimos Dimarogonas; Theodorou Evangelos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The increasing level of autonomy and intelligence of robotic systems in carrying out complex tasks can be expected to revolutionize both the industry and our everyday lives. This thesis takes a step towards automation by leveraging the power of path integral control (PIC) methods for solving control problems under such task satisfaction constraints in both a stochastic control and a reinforcement learning setting.

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

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

   Sammanfattning : 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. LÄS MER

7. 15. Towards Dense Air Quality Monitoring : Time-Dependent Statistical Gas Distribution Modelling and Sensor Planning

   Författare :Sahar Asadi; Achim Lilienthal; Amy Loutfi; Dominque Martinez; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile robot olfaction; time-dependent gas distribution modelling; temporal sub-sampling; sensor planning; artificial potential field; gas monitoring;

   Sammanfattning : This thesis addresses the problem of gas distribution modelling for gas monitoring and gas detection. The presented research is particularly focused on the methods that are suitable for uncontrolled environments. LÄS MER
