【 摘 要 】

Along with the rapid development in technology, geophysical methods emerge as one of the research alternatives. Some research requires non-destructive test to determine characteristics of an object without causing any damage, such as core rock samples. Ultrasound tomography is non-destructive methods that reconstructing cross-sectional image of the internal structure of an object by analysing the propagation of ultrasound wave. The conventional method to measure core samples that usually use for determining the position of transducer and receiver sensors is by dragging manually. This manual measurement have weaknesses in terms of efficiency and accuracy. In this research, we design prototype of the Robot RTDs-U100 to improve the quality and efficiency measurements of core samples. The magnetic sensor used to control the rotation of transducer and receiver sensors. With this robotic rotation, the position of sensors is more precise and it takes less time. Our findings of core laboratory measurements show that Robot RTDs-U100 improved measurement error from 0,32% with manual measurement to 0,12% after using Robot RTDs-U100.
