Patent attributes
Autonomous vehicle navigation is disclosed. An example lawn mower includes a vision sensor configured to capture an image of an area being approached. The lawn mower includes a processor in communication with the vision sensor and configured to divide the image into a grid of separate image sections. Each of the image sections corresponds to a respective portion of the area being approached. For each of the image sections in the grid the processor is further configured to calculate a percentage of the image section categorized as corresponding with unmowable material and assign a result value based on a comparison between the calculated percentage and one or more movement thresholds. The lawn mower includes a drive system in communication with the processor and configured to control movement of the lawn mower based on an arrangement of the result values in the grid of the image sections.
