Abstract
In a learning phase, a cleaning robot is started into an area to be cleaned. The robot measures and records the distances to left and right boundaries as it travels to determine the plan of the area. Using the measurements, it steers down the center of the area until it encounters a forward obstacle. It then determines a path for cleaning the area. In a cleaning phase, the robot follows the determined path.
