Abstract
A self-propelled electronic device comprising a housing: when an obstacle is detected ahead while the housing is moving straight forward along a outbound or a return path while it travels in a zigzag manner in a closed region, the housing travels along the obstacle such that the obstacle is located on a predetermined side of the housing, and when the housing advances by a predetermined pitch width in a direction orthogonal to a back-and-forth direction during traveling along the obstacle, the housing changes its direction and moves straight forward along a next return path or outbound path, whereas, when the housing again returns to the outbound path or return path along which it has traveled before, during traveling along the obstacle, wherein if its orientation is reversed based on its orientation when the housing has traveled along the outbound path or the return path, the housing ends traveling.
