1 What is Autonomous Navigation Construction? Back to top [PConline] The rhythm of life nowadays is accelerating. The most obvious manifestation is that the daily workload and working pace of office workers have been greatly improved. As a result, more and more urban office workers begin to clean the house. The work was entrusted to an intelligent sweeping robot. But when it comes to smart sweeping robots, consumers' impressions of them remain more in the “blind chaos†stage. In fact, for this “defective situation†of sweepers, developers have already begun to address the pain points in this industry. A more effective measure is to add the function of “building map navigation†to the sweeper. Today, we come together to talk about the construction of the intelligent sweeping machine navigation features. What is Autonomous Navigation Construction? In daily life, before we sweep the ground, we can also observe the environment that needs cleaning, and then make plans for cleaning (including the order of sweeping and the approximate route of sweeping). In fact, this is a kind of thinking that builds a plan. Posannik Polar Bear Sweeper The autonomous navigation and construction of intelligent sweepers means that the sweeping robot first performs the whole house cruise for the indoor environment before it is officially started to clean, and then draws out the floor plan of the home according to the actual conditions detected during the cruise. The robot can have a “map†when the official cleaning work is done, and the whole house is planned and cleaned according to the established 2D map to optimize the cleaning path. Navigation construction is often used with mobile phone APP In general, the sweeping machine with autonomous navigation and mapping function will have a mobile phone APP correspondingly. In this way, the 2D map created in real time during the detection of the indoor environment by the sweeping machine can be clearly returned to the user through the mobile phone APP, allowing the user to Get an overhead view from your home and use it to clean sweeps. 2 Optimize Paths to Improve Efficiency Back to Top Optimize the path to improve efficiency In the past, most of the impressions given to consumers by sweepers have remained at the stage of blindly walking away. Indeed, in the sweeping machine products that the author had previously contacted, there are indeed some products that are chaotic in terms of route, repeated cleaning, and walking along the conventional route. This is basically in line with the reaction of consumers. So, what kind of changes will happen when the sweeper has built a map? In terms of sweeping paths, each manufacturer has its unique skills, but in general it can be divided into random collisions and path planning. The so-called random collision means that the sweeping robot has a set of fixed routes. Through sweeping collisions, the sweeping function can be cleaned to every corner of the indoor environment. However, in this process, the sweeping machine will mostly appear to repeatedly sweep the area and randomly walk away. Happening. Self-built 2D map will be displayed in APP The sweeping machine with navigation and map building will build a 2D map before the formal sweeping. The sweeping path will be planned through the positioning technology to avoid the sweeping machine to take the duplicate route. This will greatly improve the sweeper's efficiency and save the user's time. . 3 related sweeper demo back to top Related sweeper demo Is the graphing function useful in the actual measurement of the sweeper? Let's take a look together! Sweep coverage test Coverage test is an important part of evaluating the cleaning performance of sweepers. Prior to testing, the author will set up 6 markers to put oats in a simulated daily home environment to see if the sweeping robot can sweep all the marks. To. The test points of this test are not only the cleaning ability of the sweeper, but also the length of time taken to complete the test and the path in the test process is also an important evaluation aspect. Sweeper with built-in function: Sweepers without a built-in function: The above several videos are regarded as a comparison between a sweeping machine with a built-in function and a built-in sweeping function. It should be noted that the above video is only used to compare sweeping sweeping paths and does not make too precise comparisons. . However, it can be seen that the two sweeping machines with built-in mapping functions have a clearer route of sweeping than sweeping machines that do not have a built-in mapping function. This also shows that the sweeper machine industry is still making progress. Labyrinth escape test In a home environment, due to the presence of furniture or appliances, there are always some slightly more complicated environments, which may trap the sweeping robot so that it can't finish cleaning tasks or even stop work. Escape ability can be said to be a big test for sweeping robots, but it is also one of the criteria for determining whether a sweeper is an excellent product. Then, is the building charting function helpful here? Sweeper with built-in function: Sweepers without a built-in function: It can be found that sweeping machines that do not have the ability to build maps seem to be "hesitant" in the face of exports in the process of escape, and there are cases where sweeping paths are repeated, and sweepers with built-in functions are relatively simple. Summary: This section of the demo video, the author more intentions, is to let everyone see the sweeping machine planning performance in the self-navigation with the improvement brought by the map, so that consumers see the sweeper industry is for us Life brings convenience and continuous improvement, rather than what brand of sweeper is better. It can be seen that a new generation of sweepers with autonomous navigation and mapping capabilities has clearly improved and progressed in path planning. Summary: The previous sweeping robots always gave consumers a feeling of “no brains walking aroundâ€, but now they are entering the era of sweeper 2.0. As one of the core technologies of sweepers, the navigation planning path has always been studied by developers. On the one hand, the new generation of sweepers will also be equipped with more intelligent path planning, and gradually tear off "not smart enough" labels for themselves. Sweeping robots are still evolving. What new technology will appear next to consumers? We might as well wait and see!
