The invention discloses a blind guide robot, a blind guide system and a blind guide method. The blind guide robot comprises a bearing moving part and a traction part, wherein the bearing moving part of the blind guide robot is provided with a control module and an ultrasonic obstacle-avoiding module which is connected with the control module, and the ultrasonic obstacle-avoiding module comprises asteering engine and an ultrasonic scanner. When moving forwards, the blind guide robot scans a front obstacle and judges whether the distance is lower than a preset threshold or not, if the distanceis lower than the preset threshold, the control module controls the steering engine to rotate a certain angle, the blind guide robot conducts scanning and judges the distance again until the distancecorresponding to the rotating angle is the safe distance, the rotation angle corresponding to the safe distance is fed back to the control module, and the control module controls the blind guide robotto make a turn to move. The blind guide robot can actively monitor the obstacle in front of a blind person, distance measurement and angle adjusting are conducted in real time so as to detect the obstacle and guide the blind person, and the mechanical structure is simple and efficient. Moreover, a plurality of steering engines and a plurality of ultrasonic scanners can be arranged, the detectionprecision is improved.

The invention relates to a detecting method and a detecting system for detecting rectangular metal bars. The detecting method includes the steps: 1 mounting a flat probe and a TR probe on a detecting device; 2 rapidly pre-scanning the rectangular metal bars to be detected at a high speed and a large distance; 3 detecting defects by the TR probe when the defects close to the surfaces of the rectangular metal bars to be detected are displayed by means of rapid pre-scanning, or detecting defects by the flat probe when the defects on cores of the rectangular metal bars to be detected are displayed by means of rapid pre-scanning; and 4 reconstructing the shapes of the rectangular metal bars according to detecting values of the flat probe and the TR probe. When detecting instructions are inputted by an input device, a driving device drives a scanning device so that the probes scan the rectangular metal bars to be detected, and detecting signals are transmitted to an industrial personal computer through an ultrasonic scanner and an ultrasonic acquisition card. After the detecting signals are processed by the industrial personal computer, detecting results are outputted.
