For some time now, robot vacuum cleaners have been quite common for the Chilean user, mainly because now there are all types and prices. In fact, this is where many doubts begin to arise about what is the big difference between the cheapest and the most expensive. The answer (as almost always) is the technology that they incorporate inside.
One of the technologies most makes the difference in a robot vacuum cleaner is LiDAR. The name may sound familiar to you, but first we’re going to briefly explain what it is and then we’ll tell you where else you can find it.
What is LiDAR?
LiDAR is the acronym for Light Detection and Ranging, or in Spanish, Light Detection and Ranges. In a nutshell, It is a device that measures distances between a point (from where it is emitted) and another. This is done through a laser beam, and the calculation logic is to measure the time delay between the laser being emitted and the target being detected.
A very good example of how it works is to make an analogy with the bat’s sonar (only in that case it’s a sound wave and in this case it’s a laser).
How does it help create a better route?
Some robot vacuum cleaners integrate a LiDAR sensor, such as Samsung’s JetBot+, for instance. This sensor helps the vacuum cleaner in many ways to know where it is standing, where it has to go and which is its route to follow. Let’s go by explaining these different applications.
The first, and I think the most important application, is that the device can identify when there is an obstacle in front of it before colliding with it, unlike the most basic vacuum cleaners that use only proximity sensors (yes, the typical one that is colliding with everything). In the case of the JetBot+, for example, can identify that it is going to collide with the legs of a chairso it brakes before, turns, analyzes with LiDAR to where there are no obstacles and continues there.
Another big difference that makes including this technology is that it is much more accurate when creating the map of the house. This is because as it progresses, it is constantly measuring distances. This allows us to know where all the walls are at once, which better demarcates the outline of the house.
Once the map of the house is done, LiDAR still continues to contribute more things. For example, if your route starts from the living room to the kitchen and that door is closed, then the vacuum cleaner will be able to decide on an alternative route first.without the need to go bump into the door to discover that it was closed.
After all, LiDAR makes a big difference to all kinds of devices that need to measure distance and depth (like high-end phones or self-driving cars, for example). It is something relatively new in robot vacuum cleaners, but I have no doubt that new applications will continue to appear that will make us get even more out of it in the short term.
