摘要： Provided are a method, apparatus, and medium for measuring a distance using a radio frequency (RF) signal. The method of measuring a distance includes setting the transmitter power of an RF signal of a signal generating module to a minimum so as to measure the longest distance when no obstacle exists, measuring a distance between the signal generating module and a fixed module using the RF signal whose transmitter power is set to the minimum, if the measured distance between the signal generating module and the fixed module is available, determining that no obstacle exists therebetween, and if the measured distance is not available, determining that an obstacle exists therebetween, and determining the distance according to the result of the determination of existence of an obstacle.

摘要： An obstruction-determining apparatus for preventing a mobile robot from being obstructed in a niche and a boundary-estimation method and medium using the obstruction-determining apparatus are disclosed. More particularly, an obstruction-determining apparatus which can determine whether a mobile robot is obstructed in a niche, and enable a mobile robot to easily escape from an obstacle if the mobile robot is determined to be obstructed in the niche, and a boundary-estimation method and medium for estimating the boundaries of an obstacle with a niche using the obstruction-determining apparatus. The obstruction-determining apparatus includes a contact module which collides with an obstacle above the mobile robot, a contact-operating module which rotates or moves linearly as a result of the collision between the contact module and the obstacle, and a sensing module which detects the rotation or the linear movement of the contact-operating module and determines whether the mobile robot is obstructed in a niche.
