1. 11. Learning for Task-Oriented Grasping

   Författare :Mia Kokic; Danica Kragic; Barbara Caputo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; robotics; computer vision; Computer Science; Datalogi;

   Sammanfattning : Task-oriented grasping refers to the problem of computing stable grasps on objects that allow for a subsequent execution of a task. Although grasping objects in a task-oriented manner comes naturally to humans, it is still very challenging for robots. Take for example a service robot deployed in a household. LÄS MER

3. 12. Planning, Projects, Practice : A Human Geography of the Stockholm Local Investment Programme in Hammarby Sjöstad

   Författare :Jonas R Bylund; Elisabeth Lilja; Bo Lenntorp; Stefan Anderberg; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Stockholm; LIP; Hammarby Sjöstad; Sustainability; Innovation; Planning; Policy; Translation; Actor-Network Theory; Laboratory; Project; Urban Specialists; Human geography; Kulturgeografi;

   Sammanfattning : Programmes and policies to support ecological sustainable development and the practice of implementation is a question of innovation rather than known and taken for granted procedure. This thesis argues a priori models concerning stability in the social sciences, and human geography especially, are less able to help us understand this practice and planning in such unstable situations.

4. 13. Wearable systems and sensors for the assessment of motor control : Development and validation of methods for clinical assessment of idiopathic normal pressure hydrocephalus

   Författare :Tomas Bäcklund; Nina Sundström; Anders Eklund; Jan Malm; Kaj Lindecrantz; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gait; step-width; heel-heigt; balance; trunk sway; idiopathic normal pressure hydrocephalus; IMU; Inter-rater reliability; kinematics; medical informatics; medicinsk informatik;

   Sammanfattning : Human gait and balance are controlled by automatic processes in the central nervous system, and in sensory and proprioceptive systems. If a disturbance occurs in any of these complex structures, it may lead to balance and gait problems. LÄS MER

5. 14. Adaptive control for robots to handle uncertainties, delays and state constraints

   Författare :Viswa Narayanan Sankaranarayanan; George Nikolakopoulos; Sumeet Gajanan Satpute; Christos Verginis; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adaptive control; barrier funciton; nonlinear control; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

   Sammanfattning : The stability and safety of robotic systems are heavily impacted by delays and parametric uncertainties due to external disturbances, modeling inaccuracies, reaction forces, and variations in dynamics. This work addresses the effects of parametric uncertainties in the application of payload transportation by robotic systems that involve time delays and state constraints. LÄS MER

7. 15. Learning Object Properties From Manipulation for Manipulation

   Författare :Püren Güler; Danica Kragic; Jeremy L. Wyatt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; manipulation; object properties; simulation; machine learning; object tracking; active exploration; sensory integration; Computer Science; Datalogi;

   Sammanfattning : The world contains objects with various properties - rigid, granular, liquid, elastic or plastic. As humans, while interacting with the objects, we plan our manipulation by considering their properties. For instance, while holding a rigid object such as a brick, we adapt our grasp based on its centre of mass not to drop it. LÄS MER
