An apparatus and a method for detecting a position of a mobile robot in
accordance with the present invention can accurately detect a position of
a mobile robot by calculating time taken for each ultrasonic signal
generated by ultrasonic signal oscillating means of a charging station to
reach the mobile robot on the basis of a point of time at which an RF
(Radio Frequency) signal emitted from the mobile robot is generated;
calculating a distance between the charging station and the mobile robot
based on the calculated reaching time; and calculating an angle between
the charging station and the mobile robot based on the calculated
distance value and a preset distance value between the ultrasonic signal
oscillating means.
