Development of Finger-Shaped Tactile Sensor Using Hemispherical Optical Waveguide
A finger-shaped tactile sensor that uses an optical waveguide to detect the contact location and the surface normal of the contacted object has been developed. The hemispherical optical waveguide is covered with an elastic cover, and LEDs are installed for the light source on the edge of the waveguide. A fiber optics plate (FOP), consisting of high-density bundled optical fibers and a position ...
متن کاملDesign and Construction of a Novel Tactile Sensor for Measuring Contact-Force, Based on Piezoelectric Effect
In this paper, design and construction of a tactile sensor for measuring contact-force is presented. Mechanism of measuring contact-force in this tactile sensor is based on impedance changing of piezoelectric crystal and voltage of different points in circuit as a result of applying force on the crystal. By considering a specific point in the circuit and recording the changes of its voltage, ma...
متن کاملContact Region Estimation Based on a Vision-Based Tactile Sensor Using a Deformable Touchpad
A new method is proposed to estimate the contact region between a sensor and an object using a deformable tactile sensor. The sensor consists of a charge-coupled device (CCD) camera, light-emitting diode (LED) lights and a deformable touchpad. The sensor can obtain a variety of tactile information, such as the contact region, multi-axis contact force, slippage, shape, position and orientation o...
متن کاملA Finger-Shaped Tactile Sensor for Fabric Surfaces Evaluation by 2-Dimensional Active Sliding Touch
Sliding tactile perception is a basic function for human beings to determine the mechanical properties of object surfaces and recognize materials. Imitating this process, this paper proposes a novel finger-shaped tactile sensor based on a thin piezoelectric polyvinylidene fluoride (PVDF) film for surface texture measurement. A parallelogram mechanism is designed to ensure that the sensor applie...
متن کاملDesign, Modeling, and Construction of a New Tactile Sensor for Measuring Contact-Force
This paper presents the design, modeling, and testing of a flexible tactile sensor and its applications. This sensor is made of polymer materials and can detect the 2D surface texture image and contact-force estimation. The sensing mechanism is based on the novel contact deflection effect of a membrane. We measure the deflection of the membrane with measuring the strain in the membrane with emb...
