A system for use in maintaining a wind turbine blade includes a motorized apparatus sized to fit within an interior cavity of the wind turbine blade and configured to travel along a length of the wind turbine blade on an interior surface when the wind turbine blade is in a substantially horizontal position. The motorized apparatus includes a body, a drive system configured to move the body, and a camera coupled to the body. The camera is configured to capture at least one image of the interior surface. The system also includes a controller configured to map the at least one image onto a model of the interior surface. The system also includes an operator interface including a display device. The operator interface is configured to display the model on the display device and receive user input allowing an operator to interact with the model.
