Optical Fiber Proximity Sensor For Robotics Applications

The paper presents a conception of an optical fiber proximity sensor designed for applications in robotics. A theoretical model of the sensor is offered as well as its computer analysis, including an examination of the effects of the sensor design parameters on its characteristics.Some results of experimental studies on the sensor are presented together with an example of the sensor's application in an industrial robot for the detection of obstacles on the robot arm's trajectory and control of their avoidance.
