Control Strategy of Pipeline Robot
Journal of Physics: Conference Series, 2021 Abstract The detection of pipeline in service is very important, but the existing manual detection has blind spots, long cycle, high risk, low precision and high cost. Therefore, it is very important to develop a mobile detection robot to replace manual inspection. This paper mainly introduces the control strategy of pipeline robot.
