Mobile robot and navigating method for mobile robot

A mobile robot comprising,

• a processor module, and a distance sensor, an auxiliary obstacle avoiding module, and an interacting module which are all connected with the processor module;
• the distance sensor is configured to scan an operating space of the mobile robot to build an environmental map, and indicate location of obstacle in the environmental map, the distance sensor sending the environmental map to the processor module, the processor module controlling movement of the mobile robot according to the environmental map;
• the auxiliary obstacle avoiding module is configured to detect obstacle and cliff boundary in a sensing blind area of the distance sensor while the mobile robot is moving, and transfer position information of the obstacle and cliff boundary in the sensing blind area to the processor module, the processor module marking the position information of the obstacle and cliff boundary in the sensing blind area on the environmental map, and delivering the environmental map to the interacting module so as to enable a subscriber to input virtual obstacle information as needed into the environmental map through the interacting module, the virtual obstacle information being fed back to the processor module;
• the processor module is configured to update the environmental map according to the virtual obstacle information, and plan movement path for the mobile robot according to the environmental map.
