2. 1. Learning Object Properties From Manipulation for Manipulation

   Author : Püren Güler; Danica Kragic; Jeremy L. Wyatt; KTH; []
   Keywords : 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. Thin metal films on weakly-interacting substrates : Nanoscale growth dynamics, stress generation, and morphology manipulation

   Author : Andreas Jamnig; Kostas Sarakinos; Gregory Abadias; Gregory Thompson; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin films; magnetron sputter-deposition; in situ and real-time characterization; early film growth stages; residual stress; manipulation of morphology; Couches minces; pulvérisation magnétron; caractérisation in situ en temps réel; premiers stades de croissance; contraintes résiduelles; manipulation de morphologie;

   Abstract : Vapor-based growth of thin metal films with controlled morphology on weakly-interacting substrates (WIS), including oxides and van der Waals materials, is essential for the fabrication of multifunctional metal contacts in a wide array of optoelectronic devices. Achieving this entails a great challenge, since weak film/substrate interactions yield a pronounced and uncontrolled 3D morphology. READ MORE

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

   Author : Ingvars Birznieks; Umeå universitet; []
   Keywords : 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. Ultrasonic Fluid and Cell Manipulation

   Author : Mathias Ohlin; Martin Viklund; Hans Hertz; Peter Glynne-Jones; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D cell culture; Acoustic streaming; Acoustofluidics; Cell manipulation; High-resolution imaging; Multi-well; Microplate; Natural killer cell; Piezo; Radiation force; Solid tumor; Solubilization; Spheroid; Standing wave; Temperature control; Transducer; Trapping; Ultrasonic; Fysik; Physics; Biological Physics; Biologisk fysik;

   Abstract : During the last decade, ultrasonic manipulation has matured into an important tool with a wide range of applications, from fundamental cell biological research to clinical and industrial implementations. The contactless nature of ultrasound makes it possible to manipulate living cells in a gentle way, e.g. READ MORE

7. 5. A behavior-based control system for mobile manipulation

   Author : Zbigniew Wasik; Alessandro Saffiotti; Dimiter Driankov; Bruno Siciliano; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; behavior-based systems; vision-based manipulation; mobile manipulation; fuzzy logic; intelligent control; autonomous robotics; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

   Abstract : The field of industrial robotics can be defined as the study, design and use of robot manipulators for manufacturing. Although the problem of designing a controller for industrial robots has been subject of intensive study, a number of assumptions are usually made which may seriously limit the applicability of these robots.
