  1. 1. To grip and not to slip sensorimotor mechanisms in reactive control of grasp stability

    Författare :Charlotte Häger Ross; Roland S. Johansson; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; human; hand; precision grip; grasp force; friction; cutaneous mechanoreceptors; sensorimotor integration; motor control;

    Sammanfattning : The reactive control of fingertip forces maintaining grasp stability was examined in man during a prehensile task. Blindfolded subjects used the precision grip between the tips of index finger and thumb to restrain an object that was subjected to unpredictable load forces. These were delivered tangential to the parallel grip surfaces of the object. LÄS MER

  2. 2. Learning to Assess Grasp Stability from Vision, Touch and Proprioception

    Författare :Yasemin Bekiroglu; Danica Kragic; Erhan Oztop; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robotic grasping; Machine Learning; Tactile Sensing;

    Sammanfattning : Grasping and manipulation of objects is an integral part of a robot’s physical interaction with the environment. In order to cope with real-world situations, sensor based grasping of objects and grasp stability estimation is an important skill. LÄS MER

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

    Detta är en avhandling från Umeå : Integrativ medicinsk biologi

    Författare :Ingvars Birznieks; [2003]
    Nyckelord :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; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; fysiologi; Physiology;

    Sammanfattning : 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. LÄS MER

  4. 4. Holistic Grasping: Affordances, Grasp Semantics, Task Constraints

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Martin Hjelm; Danica Kragic; Markus Vincze; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; robotics; robotic grasping; grasping; cognition; embodied cognition; computer vision; machine learning; artificial intelligence; AI; Gaussian process; Gaussian process latent variable model; GPLVM; 3D vision; point cloud features; robotik; manipulation; datorseende; maskininlärning; artificiell intelligens; kognition; Datalogi; Computer Science;

    Sammanfattning : Most of us perform grasping actions over a thousand times per day without giving it much consideration, be it from driving to drinking coffee. Learning robots the same ease when it comes to grasping has been a goal for the robotics research community for decades. LÄS MER

  5. 5. Adaptive Grasping Using Tactile Sensing

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Emil Hyttinen; Danica Kragic; Renaud Detry; Giacomo Spampinato; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robotics; Grasping; Tactile Sensing; Computer Science; Datalogi;

    Sammanfattning : Grasping novel objects is challenging because of incomplete object data and because of uncertainties inherent in real world applications. To robustly perform grasps on previously unseen objects, feedback from touch is essential. In our research, we study how information from touch sensors can be used to improve grasping novel objects.
