  2. 1. Learning Object Properties From Manipulation for Manipulation

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

    Abstract : 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. READ MORE

  4. 2. Safe Robotic Manipulation to Extract Objects from Piles : From 3D Perception to Object Selection

    Author : Rasoul Mojtahedzadeh; Achim J. Lilienthal; Todor Stoyanov; Abdelbaki Bouguerra; Erik Schaffernicht; Patric Jensfelt; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Object Selection; Object Pose Refinement; Gravitational Support Relation; Inter-penetration Resolving; 3D Ranging Sensor Evaluation; Datavetenskap; Computer Science;

    Abstract : This thesis is concerned with the task of autonomous selection of objects to remove (unload) them from a pile in robotic manipulation systems. Applications such as the automation of logistics processes and service robots require an ability to autonomously manipulate objects in the environment. READ MORE

  5. 3. Tactile Sensory Control of Dexterous Manipulation in Humans

    Author : Ingvars Birznieks; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; cutaneous sensibility; tactile afferents; fingertip force; grasp stability; human hand; manipulation; object shape; precision grip; sensorimotor control; coding; Fysiologi; Physiology; Fysiologi; fysiologi; Physiology;

    Abstract : During dexterous manipulation with the fingertips, forces are applied to objects' surfaces. To achieve grasp stability, these forces must be appropriate given the properties of the objects and the skin of the fingertips, and the nature of the task. READ MORE

  6. 4. Learning Structured Representations for Rigid and Deformable Object Manipulation

    Author : Michael C. Welle; Danica Kragic; Dimitry Berenson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Representation learning; Object Manipulation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The performance of learning based algorithms largely depends on the given representation of data. Therefore the questions arise, i) how to obtain useful representations, ii) how to evaluate representations, and iii) how to leverage these representations in a real-world robotic setting. READ MORE

  7. 5. To select one hand while using both : neural mechanisms supporting flexible hand dominance in bimanual object manipulation

    Author : Anna Theorin; Roland Johansson; Fredrik Ullén; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; object manipulation; bimanual coordination; action selection; cerebral cortex; functional laterality; humans; hand; magnetic resonance imaging; transcranial magnetic stimulation; electromyography; Physiology; Fysiologi; fysiologi; Physiology;

    Abstract : In daily activities, the brain regularly assigns different roles to the hands dependingon task and context. Yet, little is known about the underlying neural processes. Thiscertainly applies to how the brain, where each hemisphere primarily controls onehand, manages the between-hand coordination required in bimanual objectmanipulation. READ MORE
