Embodiment Construction

[0023] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0024] Such as figure 2 As shown, in an example of the present invention, it includes a housing, an infrared light emitting module 1, an infrared light emitting lens group 2, an infrared light receiving lens group 3, an optical signal processing unit (epc chip) 4, and a single-phase DC motor 5 , fixed-ratio parallel shaft gearbox, slip ring and corresponding drive circuit.

[0025] (1) After the infrared emission module 1 receives the measurement command, it drives the infrared LED to emit infrared light in a current modulation mode, and after being focused by the infrared light emission lens group 2, it directly emits into the environment.

[0026] (2) Infrared light propagates in the air, and it is reflected and scattered when encounter...

Abstract

The invention discloses an intelligent obstacle avoiding and positioning system for a floor sweeping robot, and the system comprises a housing, an infrared light transmitting module, an infrared light transmission lens group, an infrared light receiving lens group, an optical signal processing unit, a wireless signal transmission module, a single-phase DC motor, a fixed-ratio parallel shaft gear case, a sliding ring, and corresponding drive circuits. The system is compact in structure, can accurately and specifically recognize the distance of an obstacle and judge the size of the obstacle, and provides reliable physical basis for the intelligent judgment of the floor sweeping robot.

Description

[0001] The invention relates to the field of intelligent obstacle avoidance and positioning of a sweeping robot, in particular to an obstacle avoidance and positioning system and method for a sweeping robot. Background technique [0002] Obstacle avoidance, environmental map drawing and work planning are important topics in the field of robotics. In order to better complete the task, the sweeping robot needs to generate a map of its working environment, and then plan the most reasonable plan based on the understanding of this environmental map. Working path, improve cleaning efficiency. [0003] At present, the popular sweeping robot in the market is based on the contact navigation of the collision sensor. The sweeping robot changes the working path after a collision. Since it cannot make intelligent judgments on obstacles, such as the volume and type of obstacles, there is a cleaning coverage. Disadvantages such as low rate. And it will cause danger or loss when it collides ...
