REMOTE CONTROL METHOD AND A SYSTEM OF A MOBILE ROBOT USING A FUZZY OBSTACLE AVOIDANCE TECHNOLOGY, CAPABLE OF AUTONOMICALLY AVOIDING AN OBSTACLE BY A ROBOT WHILE OPERATING BY A REMOTE CONTROL

摘要

PURPOSE: A remote control method and system of a mobile robot using a fuzzy obstacle avoidance technology are provided to improve the reliability of a remote control because a self-regulated obstacle avoidance of a robot is proceed by using modus ponens and modus tollens of a fuzzy obstacle.;CONSTITUTION: A remote control method of a mobile robot using a fuzzy obstacle avoidance technology is as follows. When a robot operates by a remote control, first output fuzzy sets are composed because input fuzzy sets according to an angle between the robot and a target and second input fuzzy sets according to a distance between the robot and target are applied for a modus ponens(S110). Third input fuzzy sets are composed according to an angle between the robot and an obstacle obtained by an ultrasonic sensor of the robot and fourth input fuzzy sets are composed according to the distance between the robot and obstacle. The third and fourth input fuzzy sets are applied for a modus tollens so that second output fuzzy sets are composed(S120). A relevance with respect to the first output fuzzy sets is calculated by using the relevance with respect to the first to the forth input fuzzy sets(S130). A avoidance angle of the robot is calculated by using the relevance with respect to the first output fuzzy sets(S140).;COPYRIGHT KIPO 2012
