[0277] 3. This paper solves the mechanical motion design problems such as precise positioning of core samples, grabbing of samples of different specifications, batch transmission, wiping process and sample flow route. For the research and development of mechanical transmission and weighing arms, it is necessary to finely design the arm movement route, and through multiple simulation tests and corrections, the accuracy and success rate required for the test are achieved to reach more than 95%.

Based on the porosity calculation formula and the analysis and judgment experience of the data correctness, the porosity and accuracy of the samples are calculated and judged, and the sample numbers in doubt are proposed. In addition, automatic calibration can be achieved to reduce the time and cost of the experiment.
