Abstract: There is provided a moving robot including a light projector, an image sensor and a processing unit. The light projector projects a vertical light segment and a horizontal light segment toward a moving direction. The image sensor captures, toward the moving direction, an image frame containing a first light segment image associated with the vertical light segment and a second light segment image associated with the horizontal light segment. The processing unit recognizes a plush carpet in the moving direction when a vibration intensity of the second light segment image is higher than a predetermined threshold, and an obstacle height calculated according to the first light segment image is larger than a height threshold.

Abstract: An anti-collision mechanism comprises a body, a collision baffle, a magnetic element, and a magnetic field sensor, and the anti-collision mechanism is configured to be applicable to a sweeping robot. The magnetic field sensor is arranged at a distance from the magnetic element, the magnetic field sensor is configured to detect a change in the magnetic field intensity caused by a change in the distance between the magnetic field sensor and the magnetic element. When the collision occurs, the magnetic element is closer to the magnetic field sensor to make the magnetic field intensity change, thus generating signals to stop or turn the sweeping robot, which can realize the obstacle avoidance of the sweeping robot and enhance the service life. The sweeping robot is also provided.

Abstract: Systems and methods for initializing a robot to autonomously travel a route are disclosed. In some exemplary implementations, a robot can detect an initialization object and then determine its position relative to that initialization object. The robot can then learn a route by user demonstration, where the robot associates actions along that route with positions relative to the initialization object. The robot can later detect the initialization object again and determine its position relative to that initialization object. The robot can then autonomously navigate the learned route, performing actions associated with positions relative to the initialization object.
