With the development in egocentric vision, skill measurement has been recently proposed as a novel topic in this emerging field. In this report, we record the the experimenter’s first-person videos in Wet labratories (wetlab), and measure his/her operative skills. Specifically, given the videos of expert and amateur, we analyze their head motions, hands motions, eye-hand coordinations and key-m...

The paper describes the recent advancements gained on the MPI motion simulator project. The aim of this project is the use of an anthropomorphic robot as actuation system for a motion platform intended for real time flight simulation. Almost all commercially available motion platforms rely on the so called Stewart platform, that is a 6-DOF platform that can bear high payloads and can achieve hi...

Grasping and manipulation by hands can be considered as one of inevitable functions to achieve the performances desired in humanoid operations. When a humanoid robot manipulates an object by his hands, each finger should be well-controlled to accomplish a precise manipulation of the object grasped. So, the trajectory of each joint required for a precise finger motion is fundamentally necessary ...

BACKGROUND In the continuum between a stroke and a circle including all possible ellipses, some eccentricities seem more "biologically preferred" than others by the motor system, probably because they imply less demanding coordination patterns. Based on the idea that biological motion perception relies on knowledge of the laws that govern the motor system, we investigated whether motorically pr...

In this paper, we propose an entirely new strategy for dynamic manipulation of sheet-like flexible objects. As one example, we consider dynamic folding of a cloth by a highspeed robot system consisting of two high-speed multifingered hands mounted on two sliders and a high-speed vision system. First, the dynamic folding performed by a human subject is analyzed in order to extract the necessary ...

The actualization of a simple affordance task-grasping and moving wooden planks of different sizes using either one or two hands-was assessed in the context of task-relevant (plank sequence, plank presentation speed) and task-irrelevant (cognitive load) manipulations. In Experiment 1, fast (3 s/plank) and self-paced ( approximately 5 s/plank) presentation speeds revealed hysteresis; the transit...

This paper presents a robust control approach to control the movement of a prosthetic hand based on an estimation of the finger angles using surface electromyographic (sEMG) signals. All the available prosthesis uses the motion control strategy which is pre-programmed get initiated when some threshold value of the measured sEMG signal is reached for a particular motion set. Here we use a novel ...
