PROBLEM TO BE SOLVED: To provide a method for detecting the position of a mobile robot and an apparatus therefor, which can precisely and minutely detect the position of the mobile robot, on the basis of the time difference between infrared signal and ultrasonic signal. SOLUTION: The position of the mobile robot is detected, by serially performing a step of receiving the infrared signal and the plurality of ultrasonic signals and for calculating the time difference between the infrared signal received and each ultrasonic signal, and a step of detecting the position of the mobile robot on the basis of the calculated time difference values and a plurality of distance values between a plurality of ultrasonic wave oscillation parts for oscillating the ultrasonic signals stored in advance.
