چکیده

This paper presents a unique design for tactile sensing: embedding as many receptors as possible randomly in soft material so as to provide different kinds of sensing modalities. Based on this design principle, an anthropomorphic fingertip has been developed. The fingertip consists of two silicon rubber layers of different hardness containing two kinds of receptors, strain gauges and PVDF (polyvinylidene fluoride) films distributed randomly as receptors. The experimental results are shown to demonstrate its sensing ability such as object discrimination.

Sensing the texture of surfaces by anthropomorphic soft fingertips with multi-modal sensors

This paper describes the development of a humanlike multi-modal soft finger and its ability to sense the texture of objects. This fingertip has two silicon rubber layers of different hardness; strain gauges and PVDF films are randomly distributed as tactile sensors. Owing to the dynamics of the silicon between sensors, the fingertip is supposed to have several sensor modalities. Preliminary exp...

iCub Tactile Sensing System: Current State and Future Directions

Robots that can dexterously manipulate objects are important in applications such as domestic robots, industrial robots and emergency response robots. Several tactile sensors have been proposed, however, only a few can be fully integrated with robotic hands. A typical problem that prevents integration is lack of sensors that can be deployed on curved surfaces. In this paper we present a new fin...

Transverse Sensing of Simply Supported Truncated Conical Shells

Modal signals of transverse sensing of truncated conical shells with simply supported boundary condition at both ends are investigated. The embedded piezoelectric layer on the surface of conical shell is used as sensors and output voltages of them in considered modes are calculated. The Governing sensing signal displacement equations are derived based on the Kirchhoff theory, thin-shell assumpt...

An approach to integrated tactile perception

This paper presents an integrated approach to tactile perception, both in terms of data acquisition and of data interpretation. In humans, touch sensing is implemented through a number of different sensing elements embedded in: the skin. The interpretation of perceived data to the level of detection of basic features, such as material, shape of surjface, shape of contact, is achieved by integra...
