![]() ![]() Oil storage tank is an essential and important infrastructure in the petroleum, chemical, and other industries. ![]() In addition, by measuring the acoustic emission distance, the three-point positioning algorithm can be used to achieve the calculation of the robot position detection in the proposed method, and the average positioning error on the spiral path is only 0.0748 ± 0.0032. Compared with the state-of-the-art, the RPF method reduced the average RMSE by 9.49%. We obtained accurate and smooth planning results. Specifically, we design a preset spiral path according to the shape of the tank bottom, and a rotating potential field (RPF) near the obstacle is added to avoid the problem of path planning falling into a local minimum. This article proposes a path planning and location algorithm for the large tank bottom detection robot. Besides, the positioning of the tank bottom detection robot is not accurate. However, the existing path planning algorithm of the tank bottom detection robot is easy to fall into the local minimum, and the path is not smooth. With the development of robot technology, inspection robots have been applied to the defect detection of large tanks. ![]()
