Summary:PURPOSE: A method and a device for detecting an obstacle of a robot are provided to deal with the situation properly and determine the situation and the operation of a robot by estimating a position of an obstacle quickly. CONSTITUTION: A vision sensor(10) detects an image. A database stores information related to the previously obtained image. A comparison image extractor(30) extracts the past image to compare with the current position from the database. A comparison region selector(40) selects the comparison image commonly existing in the extracted image sensor and the inputted current image from the image sensor. An image converter converts one of the past image and the current image to the image corresponding to the other position based on the characteristic of the comparison region. An obstacle detector(60) estimates the obstacle position by comparing the converted image with the other.
