Abstract: Aiming at the difficulties of ultrasound scattering detection for multidegree of freedom pose adjustment, analyzing ultrasonic testing parallel robot in kinematic model was introduced. Ultrasonic backscatter detection and parallel robot integration technology was used to improve the problem. Because of the specific control requirements for ultrasonic transducer′s position, testing robot mathematical was modeled. A method to calculate the pose control was proposed. Pose analysis was simulated through Matlab. Through this pose analysis, the result was anticipated to provide accurate control parameters for computercontrolled transducer of surface testing. At Cscan experiments, comparing the percentage of the noise area, the experimental results indicate that ultrasonic testing parallel robot improved the accuracy of ultrasonic transducer′s pose. Noise is reduced, and signal to noise ratio is improved.
