In this paper, we illustrate the low level reflex control used to govern an anthropomorphic artificial hand. The paper develops the position and stiffness control strategy based on dynamic artificial neurons able to simulate the neurons acting in the human reflex control. The controller has a hierarchical structure. At the lowest level there are the receptors able to convert the analogical sign...

This paper presents the current work progress of HIT/DLR Dexterous Hand. Based on the technology of DLR Hand II, HIT and DLR are jointly developing a smaller and easier manufactured robot hand. The prototype of one finger has been successfully built. The finger has three DOF and four joints, the last two joints are mechanically coupled by a rigid linkage. All the actuators are commercial brushl...

Engineering zinc finger protein motifs for specific DNA targets in genomes is critical in the field of genome engineering. We have developed a computational method for predicting recognition helices for C2H2 zinc fingers that bind to specific target DNA sites. This prediction is based on artificial neural network using an exhaustive dataset of zinc finger proteins and their target DNA triplets....

Two-sided pressure input is common in everyday interactions such as grabbing, sliding, twisting, and turning an object held between thumb and index finger. We describe and demonstrate a research prototype which allows for twosided multitouch sensing with continuous pressure input at interactive rates and we explore early ideas of interaction techniques that become possible with this setup. The ...

In this work, we report a novel method of fabricating Glass-PDMS-glass fluidic diode using CO2 laser ablation that avoids conventional laborious procedures such as spin coating and molding of PDMS. By using this type of fluidic diode we constructed a finger-driven microdevice that can meter and deliver (MAD) multiple solutions in parallel, and the efficiency and accuracy of the MAD function was...

We propose a novel interface in mobile environment called “Ubi-Finger” that realizes sensuous operations for PDA and information appliances by gestures of fingers. Since gestures are usual methods of non-verbal communications and enables sensuous operations for users, many researches on them carried out especially in the field of Virtual Reality. However most of those existing gesture-input sys...

This letter presents the design, prototype and kinematic model of a new adaptive underactuated finger with an articulated skin/surface that is able to bend and, at same time, provides active rolling motion along its central axis while keeping configuration (see Fig. 1). The design based on planar chain overlapping spherical phalanxes are tendon-driven. has surface made external hollow universal...

background: as students' hookah use has become a widespread problem in the developing countries, it is time to understand the cognitive determinants of students' decisions to do so. this study aimed to investigate the roles of psychological and demographic factors associated with hookah use among male high school students. method s: this descriptive-analytical study was performed among 601 high...

This paper presents the design of a new low-cost, easy operation hand having three 1 dof anthropomorphic fingers with human size. Experimental results on human cylindrical grasping have been used for designing a 1 dof anthropomorphic finger having human size. The mechanical design of this finger has been mainly focused on a suitable articulated mechanism. This mechanism transmits the power to t...
