Abstract: The present invention relates to a method of controlling a robot for bridge inspection. In the present invention, whether a defect image is being received from a robot device is determined. As a result of the determination, when the defect image is being received, a current location of the robot device is stored. Whether a predetermined period of time has been elapsed after the storage of the current location is determined. When the predetermined period of time has elapsed, a control command for moving the robot device to a prestored location is output. Whether a defect image at a same location as the prestored location is being received is determined. When the defect image at the same location is being received, a defect image at a previous time is compared with a defect image at a current time. A result of the comparison is displayed.
