We describe the development of a tactile hemispherical soft fingertip (FT) of a size similar to that of a human thumb. The sensory core consists of a microscaled force/torque sensor that can output one component of force and two components of moment simultaneously, which was developed beforehand. This sensor is embedded in a polyurethane rubber(More)
In this paper, we describe the design, fabrication and calibration results of a 6-degree of freedom force-moment micro sensing chip utilizing the piezoresistance effect in silicon. The sensing chip is designed to be able to simultaneously detect three components of force and three components of moment in three orthogonal directions. Conventional p-type and(More)
We have investigated the deformation of a soft fingertip when it slides. This process was first simulated using the non-linear Finite Element Analysis (FEA) method. Based on the results of this simulation, we designed experiments to observe the sliding and object grasping of a soft fingertip, in which a 3-DOF (degree of freedom) micro force/moment sensor(More)
This paper describes our initial research on development of a tactile sensor, which can be employed in anthropomorphic soft fingertips, with multi-sensing points that uses 3-DOF micro force moment sensing chips (MFMS) which are able to measure forces up to nearly a Newton. Three sensing points are integrated on a compact printed circuit board with an(More)
In this paper, we show a novel tactile sensor fabricated by embedding a Micro-Force/Moment Sensor inside a hemispherical soft fingertip, which is applicable to the object manipulation using robotic hands. This sensor is produced by MEMS technology, designed to detect one force component (Fz) and two moment components (Mx,My). The structure is composed of a(More)
A prototype advanced robot for remote or automatic maintenance and inspection of nuclear power plant facilities has been developed by the 'Advanced Robot Technology' promoted by the Agency of Industrial Science and Technology. This paper deals with the prototype advanced robot and results of the experiments executed in a verification test facility. The(More)
This paper reports the theoretical and experimental investigations on the strain sensing effect of a two dimensions (2D) photonic crystal (PhC) nanocavity resonator. By using the finite element method (FEM) and finite difference time domain (FDTD) simulations, the strain sensitivity of a high quality factor PhC nanocavity was calculated. Linear(More)
With the development of data processing technology, the number of people using a computer is rapidly growing now. And they came to use it in the everyday life of ordinary homes. However, it is hard for elderly people and disabled persons to treat an interface device such as a mouse and a keyboard. For this reason, the dialog system is needed that permits(More)
