1. 1. Programming by demonstration of robot manipulators

   Författare :Alexander Skoglund; Rainer Palm; Honghai Liu; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; programming-by-demonstration; imitation learning; hand-state; next-state-planner; fuzzy time-modeling approach; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap; Människa-dator interaktion; Human-Computer Interaction;

   Sammanfattning : If a non-expert wants to program a robot manipulator he needs a natural interface that does not require rigorous robot programming skills. Programming-by-demonstration (PbD) is an approach which enables the user to program a robot by simply showing the robot how to perform a desired task. LÄS MER

3. 2. Towards Manipulator Learning by Demonstration and Reinforcement Learning

   Författare :Alexander Skoglund; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Manipulation; learning; robot learning from demonstration; programming by demonstration; imitation in robotics.; Computer science; Datavetenskap;

   Sammanfattning : This thesis address how robotic arms, called manipulators, can learn a task demonstrated by a teacher. The concept of showing a robot a task, instead of manually programming it, is appealing since it makes it easier to instruct robots. LÄS MER

4. 3. Robot Task Learning from Human Demonstration

   Författare :Staffan Ekvall; Danica Kragic; Marcus Vincze; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robotics; Machine Learning; Artificial Intelligence; Computer Vision; Programming by Demonstration; Grasp Mappping; Grasp Recognition; Robot Grasping; Planning; Autonomous Robots; Computer science; Datalogi;

   Sammanfattning : Today, most robots used in the industry are preprogrammed and require a welldefined and controlled environment. Reprogramming such robots is often a costly process requiring an expert. By enabling robots to learn tasks from human demonstration, robot installation and task reprogramming are simplified. LÄS MER

5. 4. Look-ahead Control of Heavy Trucks utilizing Road Topography

   Författare :Erik Hellström; Lars Nielsen; Torkel Glad; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; predictive control; dynamic programming; Automatic control; Reglerteknik;

   Sammanfattning : The power to mass ratio of a heavy truck causes even moderate slopes to have a significant influence on the motion. The velocity will inevitable vary within an interval that is primarily determined by the ratio and the road topography. LÄS MER

7. 5. Approaches to accelerate methods for solving systems of equations arising in nonlinear optimization

   Författare :David Ek; Anders Forsgren; Jacek Gondzio; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nonlinear optimization; mathematical programming; interior-point methods; approximate solutions to systems of linear equations; method of conjugate gradients; quasi-Newton methods; modified Newton methods; Ickelinjär optimering; matematisk programmering; inre-punktsmetoder; approximativa lösningar till linjära ekvationssystem; konjugerade gradientmetoden; kvasi-Newtonmetoder; modifierade Newtonmetoder.; Optimization and Systems Theory; Optimeringslära och systemteori;

   Sammanfattning : Methods for solving nonlinear optimization problems typically involve solving systems of equations. This thesis concerns approaches for accelerating some of those methods. In our setting, accelerating involves finding a trade-off between the computational cost of an iteration and the quality of the computed search direction. LÄS MER
