  1. 21. On Robot Feedback from Range Sensors : Reliable Control by Active Reduction of Uncertainty and Ambiguities

    Författare :Jonas Nygårds; John Hallam; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robot gripping and docking; LQG-feedback; posture estimation; Gaussian sum; optronic sensing; sheet of light range camera; time-of-flight laser; specular reflection s; multiple scattering; range ghosts ; active reduction of ambiguities; reliability; uncertainty; tolerances;

    Sammanfattning : This thesis is on modelling and experimental tests when non contact sensing isused for feedback control in robotics. The motion of the robot is to be controlled relative to objects in the surrounding workspace during operations like gripping/docking, surface following, shape measuring etc. LÄS MER

  3. 22. Process Development for Electron Beam Melting of 316LN Stainless Steel

    Författare :Stefan Roos; Lars-Erik Rännar; Andrei Koptioug; Jonas Danvind; Lars Pejryd; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; beam deflection rate; electron beam melting; energy input; material properties; microstructure; powder bed fusion; process parameters; 316LN stainless steel;

    Sammanfattning : Additive manufacturing (AM) is a technology that inverts the procedure of traditional machining. Instead of starting with a billet of material and removing unwanted parts, the AM manufacturing process starts with an empty workspace and proceeds to fill this workspace with material where it is desired, often in a layer-by-layer fashion.

  4. 23. Cooperative Planning Control and Formation Control of Multi-Agent Systems

    Författare :Alexandros Nikou; Dimos Dimarogonas; Julien Hendrickx; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Cooperative planning control is an active topic of research, with many practical applications including multi-robot systems, transportation, multi-point surveillance and biological systems. The contributions of this thesis lie in the scope of three topics: formation control, time-constrained cooperative planning control and probabilistic control synthesis, all of the them in the framework of multi-agent systems.

  5. 24. The Office - An Explorative Study : Architectural Design's Impact on Health, Job Satisfaction & Well-being

    Författare :Christina Bodin Danielsson; Magnus Rönn; Lennart Bodin; Frank Becker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; employees; office environment; office type; architectural features; functional features; architecture; experience; satisfaction; dissatisfaction; health; job satisfaction; perception; Architecture; Arkitektur;

    Sammanfattning : This doctoral thesis examines the office environment’s influence on employees’ perception oftheir workplaces, their organizations and their job satisfaction, as well as their health and wellbeing.It is based on an empirical study of 491 office employees from twenty-six companies anddivisions in large companies.

  7. 25. Reactive control and coordination of redundant robotic systems

    Författare :Yuquan Wang; Petter Ögren; Abderrahmane Kheddar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reactive control; dual-arm manipulation; mobile manipulation; ambulance positioning.; Computer Science; Datalogi;

    Sammanfattning : Redundant robotic systems, in terms of manipulators with one or twoarms, mobile manipulators, and multi-agent systems, have received an in-creasing amount of attention in recent years. In this thesis we describe severalways to improve robotic system performance by exploiting the redundancy. LÄS MER
