Abstract

A method for confining and/or modifying the movement of robotic devices by means of a boundary component. The boundary component is placed within an area co-located with the robotic device. The boundary component has a predetermined surface indentation pattern that may be discerned by a sensor component installed onto the robotic device. A robotic device configured with a line laser emitting diode, an image sensor, and an image processor detects predetermined indentation patterns of surfaces within a specific environment. The line laser diode emits the line laser upon surfaces within the filed of view of the image sensor. The image sensor captures images of the projected line laser and sends them to the image processor. The image processor iteratively compares received images against a predetermined surface indentation pattern of the boundary component. Once the predetermined indentation pattern is detected the robotic device may mark the location within the working map of the environment. This marked location, and hence boundary component, may be used in confining and/or modifying the movements of the robotic device within or adjacent to the area of the identified location. This may include using the marked location to avoid or stay within certain areas or execute pre-programmed actions in certain areas.
