Autonomous mobile robot and control method thereof

An autonomous mobile robot, adapted to move on a surface according to a moving datum plane, the autonomous mobile robot comprising:

• a first distance sensor configured to detect a first detecting distance between the first distance sensor and the surface along a first axial direction;
• a second distance sensor configured to detect a second detecting distance between the second distance sensor and the surface along a second axial direction, the first distance sensor has a first projection on the moving datum plane along the first axial direction, the second distance sensor has a second projection on the moving datum plane along the second axial direction, a distance between the first projection and the autonomous mobile robot is larger than the distance between the second projection and the autonomous mobile robot;
• and
• a control unit configured to control the autonomous mobile robot to move in a speed limited mode in response to the first detecting distance being within a first distance range that is greater than a safe distance range for which the speed of the mobile robot is not reduced, and configured to control the autonomous mobile robot to stop moving when the second detecting distance is larger than a second pre-determined distance.
