Did the floor sweeper work?

First of all, is the ability to build maps and planning cleaning, sweeping robot market there are three map planning cleaning capabilities, infrared navigation is the first sweeping robot to use, using infrared to sense obstacles and charging base, but this method of mapping ability slow response, and sometimes can not be a timely response. The second is laser navigation, which can scan 360 degrees and paint the entire environment, updating it in real-time every time it is cleaned. The third is visual navigation, which can see in front of 160 degrees or so of obstacles or garbage, can quickly identify, this kind of mapping is slower, but the accuracy is higher.  common on the market is laser navigation and visual navigation, or a combination of both. Infrared Navigation is also becoming an auxiliary role. So, when you buy a sweeping robot, you need to see what kind of navigation it has, if you buy laser navigation or visual navigation, Laser + infrared, LASER + vision, etc., as long as it is not a separate infrared navigation, the basic mapping capabilities are good, can accurately draw the surrounding environment graphics. So now the sweeping robot in the mapping ability is no problem, you can rest assured that the choice.
