摘要：A robot includes an obstacle sensing mechanism for sensing an angle formedbetween a first wall and a forward travel direction of the robot. The robot then travelsparallel to the first wall while the obstacle sensing mechanism senses a front distance ofthe robot from a wall located in front of the robot and sideward distances of the robotfrom walls located to respective sides of the robot. In response to the sensing ofchanges in the sideward distances, the robot is able to divide the area into separate cellswhich together define an environmental map of the area. That map is stored in therobot's memory.
