Abstract: Recently, many robots are used in the factory. So it is necessary that they are equipped with the safety sensor to avoid a collision between the man and the robots. The laser distance meter is generally expensive because it needs the high frequency-driven counter. A new type of area sensor with Distance-voltage transfer method by semiconductor laser, which does not need such a counter, has been studied. In this method, the time difference in proportion to the distance is observed by the averaged voltages which are obtained as the logical product between the transmitted and the received signals. The reflectivity of the obstacle depends on the surface. This sensor is designed to avoid the influence of the obstacle reflectivity. This sensor is able to detect a distance up to 3m within 10cm error. Also, it is possible to detect some obstacles around the sensor by scanning the laser. This study will realized the safety system that can observe the varying danger area synchronizing to the robot's motion.
