A robotic device is manually driven along a perimeter of a Region Of Interest (ROI) or along a Path Of Interest (POI) for future autonomous operation. An Initial Point (IP) is established by identifying a unique machine recognizable feature, for example, a Radio Frequency Identification (RFID) tag located at the IP. The robotic device is then manually driven along the perimeter or along the path and sensors carried by the robotic device collects data to characterize the ROI or POI. The sensors may include sonar, vision systems, laser, or radar devices for measuring relative positions of a wall, stairs, or obstacles. Wheel odometry may be used to track distances traveled and data fusion exercised to combine the odometry data with the sonar and/or laser measurements to model the ROI or POI. Characterization is performed by collecting points along a wall, fitting a line to the points, and finding the intersections of consecutive lines.
