Problems solved by technology
[0004] However, the current sweeping robots are only suitable for cleaning dry garbage such as dust, hair, and paper scraps. They are not suitable for liquids that are spread on the ground, such as a puddle of water spilled on the ground, or a puddle of urine from pet cats and dogs. It is suitable for cleaning, but the sweeping robot will still drive through these piles of liquid, and will suck the liquid into the dust suction duct and dust box like dry garbage, which may short-circuit the internal circuit of the machine and cause damage

Embodiment Construction
[0053] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0054] The solution of the present application is based on visual analysis, automatically detects a pool of liquid on the ground in the direction of travel of the sweeping robot, and can control the sweeping robot to automatically avoid the pool of liquid. In order to further improve the reliability of the solution, a humidity sensor can also be insta...

The invention discloses a control method of a floor sweeping robot. The method at least comprises the steps of collecting ground images in the walking direction of the floor sweeping robot through thearrangement of a vision sensor on the floor sweeping robot; judging whether or not there is a puddle of liquid on the ground in the walking direction of the floor sweeping robot according to the collected ground images; if yes, controlling the floor sweeping robot to avoid the liquid. According to the control method, the floor sweeping robot which conducts navigation based on visual analysis caneffectively conduct liquid detection to avoid the liquid, and the situation that in the sweeping process, the liquid on the ground is sucked in a dust suction air channel and a dust collection box, and the robot is possibly damaged is conveniently avoided.
Description
technical field [0001] The present application relates to the field of smart home appliances, in particular to a method for controlling a sweeping robot. Background technique [0002] Various smart home appliances have brought great convenience to people's daily life, and sweeping robots are a type of smart home appliances that have emerged in recent years and have been welcomed by people. [0003] The sweeping robot can automatically navigate based on radar detection or visual analysis, so as to clean the ground for people in an orderly manner. For a sweeping robot that navigates based on visual analysis, at least one visual sensor is provided on its body to collect images of the surrounding environment when the sweeping robot is working, analyze the images, and navigate based on the analysis results. [0004] However, the current sweeping robots are only suitable for cleaning dry garbage such as dust, hair, and paper scraps. They are not suitable for liquids that are spre...
