A dynamic tactile sensor on photoelastic effect
Certain photoelastic materials exhibit birefringent characteristics at a very low level of strain. This property of material may be suitable for dynamic or wave propagation studies, which can be exploited for designing tactile sensors. This paper presents the design, construction and testing of a novel dynamic sensor based on photoelastic effect, which is capable of detecting object slip as wel...
متن کاملPhotoelasticity Based Dynamic Tactile Sensor
The paper presents design, construction and testing of a photoelasticity based dynamic sensor which is capable of detecting slip as well as providing normal force information. Starting with investigations into mechanism of slip, an approximate model of the sensor has been developed. This model explains the design improvements necessary to provide continuous signal during slip. The theoretical m...
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 کاملA novel sensor for dynamic tactile information
We present a novel tactile sensor, which is useful for dextrous grasping with a simple robot gripper. The novel part consists of an array of capacitive sensors, which couple to the object by means of little brushes of fibers. These sensor elements are very sensitive (with a threshold of about 5 mN) but robust enough not to be damaged during grasping. They yield two types of dynamical tactile in...
متن کاملDynamic Conditions of Reflection-Type Tactile Sensor
Considering tactile sensors there are two ways to acquire object information. These are spatial sensing with two dimensional devices and fast sensing with simple devices. Because the reflection-type tactile sensor uses a reflection image, both methods can be employed. Though there exist some dynamic characteristics in these two ways. In this study, we first validate the hysteresis of the reflec...
