Design of a Highly Biomimetic and Fully-Actuated Robotic Finger

During design a mechanical structure such as a robotic finger, modeling parts and designing joints are two time-consuming steps. This paper presents a method for design and fabrication of a humanoid robotic finger that intends to mimic the human finger in ...

An Overview of Functional Magnetic Resonance Imaging Techniques for Organizational Research

Kerstin Preuschoff, Leyla Loued-Khenissi

Functional magnetic resonance imaging is a galvanizing tool for behavioral scientists. It provides a means by which to see what the brain does while a person thinks, acts, or perceives, without invasive procedures. In this, fMRI affords us a relatively eas ...

VIMO: Simultaneous Visual Inertial Model-Based Odometry and Force Estimation

Davide Scaramuzza

In recent years, many approaches to visual-inertial odometry (VIO) have become available. However, they neither exploit the robot's dynamics and known actuation inputs, nor differentiate between the desired motion due to actuation and the unwanted perturba ...

Automatic extraction of constraints in manipulation tasks for autonomy and interaction

Ana-Lucia Ureche

Tasks routinely executed by humans involve sequences of actions performed with high dexterity and coordination. Fully specifying these actions such that a robot could replicate the task is often difficult. Furthermore the uncertainties introduced by the us ...

Tracking discrete off-resonance markers with three spokes (trackDOTS) for compensation of head motion and B0 perturbations: Accuracy and performance in anatomical imaging

José Pedro Rebelo Ferreira Marques, Daniel Gallichan, João Pedro Forjaco Jorge, Frédéric Gretsch

PURPOSE: To develop a novel approach for head motion and B0 field monitoring based on tracking discrete off-resonance markers with three spokes (trackDOTS). METHODS: Small markers filled with acetic acid were built and attached to a head cap. Marker positi ...

Multi-contact tactile exploration and interaction with unknown objects

Nicolas Sommer

Humans rely on the sense of touch in almost every aspect of daily life, whether to tie shoelaces, place fingertips on a computer keyboard or find keys inside a bag. With robots moving into human-centered environment, tactile exploration becomes more and mo ...

Apparatus to apply forces in a three-dimensional space

Grégoire Courtine, Joachim von Zitzewitz

The present invention relates to a robotic system useful to unload an object/person from its weight. The robotic system is useful in locomotor rehabilitation programs and allows the manipulation of forces in a three-dimensional space with far lower actuato ...

Recent applications of UHF-MRI in the study of human brain function and structure: a review

Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques

The increased availability of ultra-high-field (UHF) MRI has led to its application in a wide range of neuroimaging studies, which are showing promise in transforming fundamental approaches to human neuroscience. This review presents recent work on structu ...

3D T 2-weighted imaging at 7T using dynamic kT-points on single-transmit MRI systems

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, Kieran O'Brien, Florent Eggenschwiler

OBJECTIVES: For turbo spin echo (TSE) sequences to be useful at ultra-high field, they should ideally employ an RF pulse train compensated for the B 1 + inhomogeneity. Previously, it was shown that a single kT-point pulse designed in the small tip-angle re ...
