METHOD OF DETECTING OUTLINES OF OBSTACLES, A MOBILE ROBOT AND A REMOTE CONTROLLER, CAPABLE OF CONTROLLING STABLY A MOBILE ROBOT BY RECOGNIZING SURROUNDING ENVIRONMENT INSTEAD AN ACCURATE MAP

摘要

PURPOSE: A method of detecting outlines of obstacles, a mobile robot and a remote controller are provided to enhance recognition rate of a user over an obstacle by extracting outlines of obstacles using an ultrasonic sensor.;CONSTITUTION: A method of detecting outlines of obstacles is as follows. Data is supplied from an ultrasonic sensor part of a mobile robot. Data indicates a first distance from the mobile robot to an obstacle(20). The outlines coordinates of the obstacle is obtained based on the first distance and a direction angle of the mobile robot. The outline of the obstacle is drawn on a map using the outlines coordinates. The mobile robot approaches to the obstacle within a specific distance. Data is supplied from an infrared sensor unit of the mobile robot. Data indicates a second distance from the mobile robot to the obstacle. The outlines of the obstacle are drawn with different colors on a map with the outlines coordinates connected in the predetermined direction according to the second distance.;COPYRIGHT KIPO 2010
