Abstract
A path tracking method and device for an in-oil inspection robot for a storage tank bottom plate in an invisible environment are provided. The method includes: determining a current position of a robot in a rasterized storage tank bottom plate drawing; when the current position is located in an inspected area, searching a cell of an uninspected area closest to the current position as a target point, and planning a moving path to the target point and a scanning path for inspecting the uninspected area where the target point is located; controlling the robot to move to the target point using a path tracking algorithm; and completing inspection of the uninspected area where the target point is located with the target point as a starting point. According to the method, a path of the robot can be planned and tracked automatically, improving inspection efficiency.
