Optical Three-axis Tactile Sensor for Robotic Fingers
Tactile sensors capable of sensing normal and shearing force produced on a robotic finger and an object are useful for fitting a dextrose hand that can be applied to tasks that require human-like handling. Examples include such manufacturing tasks as assembly, disassembly, inspection, and materials handing. Especially in the case of humanoid robots, grasping slippery or flexible objects is requ...
متن کاملSensing characteristics of an optical three-axis tactile sensor under combined loading
This paper describes precision enhancement of an optical three-axis tactile sensor capable of detecting both normal force and tangential force. The sensor’s single cell consists of a columnar feeler and 2-by-2 conical feelers. We have derived equations to precisely estimate the three-axis force from the area-sum and area-difference of the conical feelers’ contact areas by taking into account wr...
متن کاملFlexible Piezoelectric Tactile Sensor Array for Dynamic Three-Axis Force Measurement
A new flexible piezoelectric tactile sensor array based on polyvinylidene fluoride (PVDF) film is proposed for measuring three-axis dynamic contact force distribution. The array consists of six tactile units arranged as a 3 × 2 matrix with spacing 8 mm between neighbor units. In each unit, a PVDF film is sandwiched between four square-shaped upper electrodes and one square-shaped lower electrod...
متن کاملMeasurement Principles of Optical Three-Axis Tactile Sensor and its Application to Robotic Fingers System
A tactile sensor is a device that can measure a given property of an object or contact event through physical contact between the sensor and the object. Traditionally, tactile sensors have been developed using measurements of strain produced in sensing materials that are detected using physical quantities such as electric resistance and capacity, magnetic intensity, voltage and light intensity ...
متن کاملSensorization of Robotic Hand Using Optical Three-Axis Tactile Sensor: Evaluation with Grasping and Twisting Motions
Problem statement: Sensitization of robot hand is still remaining as crucial issue since most of robot hand systems nowadays are only capable to grasp a predefined specific object. It is still difficult for robot hand system to realize human-like tactile sensation. Some common problems in robot hand system are low accuracy sensing device, sensors are not robust enough for long time work and hea...
