Are you smart “robots vacuum cleaners”? We consider sensors for navigation

A robot vacuum cleaner in the house no one no one surprise. Someone has them, someone wants to buy, someone considers toy. And manufacturers use these desires, and try to sell us something. Something, because the marketing departments of leather companies are climbing, coming up with the taking titles and endowing simple solutions with non-existent capabilities. Further I will try to decompose the device of robots-vacuum cleaners “on the shelves” and tell about their sensors.

I will not focus on their internal device, fees, processors, cleaning mechanisms themselves. My task is to show that there is nothing supernatural in these home assistants and they are built on the basic principles, a little-old familiar to anyone touching robotics. I myself have a robot vacuum cleaner from A-brand (Homebot), so sometimes I will tell and on his example, too, and this is not a brand advertising. over, the homemade vacuum cleaner carries a proud smoke “fool”, as it works hard, but.

But let’s start with the design because it will explain this or that form. In fact, almost all homemade vacuum cleaners are a two-wheeled trolley with one or two support wheels. Form 99% Round models. Why a circle, not a square or triangle? Enough to look at these pictures.

The square vacuum cleaner in the theory will carefully remove all the angles, since we have in most cases the room and furniture with straight corners, but stopping into the angle, he will not be able to turn around, and when moving along the wall can be stuck. Taking into account the fact that the vacuum cleaners are remobated “line” (this is called Zigzag cleaning algorithm and about it, if it is interesting, we can talk later), such a robot will experience certain problems with routes. Yes, there are manufacturers with a “rectangular” nose (Hobot, Electrolux and others), but an evolutionary such form almost died.

The round form also has its advantages (two-wheeled robot cart and his symmetrical form allows it to turn around in place) and its cons, as brushes may not get to the garbage in the corners, and make them very long too problematic. And even if the manufacturer declares that he has a square body, it will be cut (as in the case of my robot), since in fact it will be a slightly trimmed circle.

The round form again gives more space to place the mechanisms and batteries and “according to the classics” we have a front robot brushes, in the middle a hole for suction of garbage and a container for it, and behind the rear of the turbine of the vacuum cleaner and batteries.

And this form determines those sensors and the principles of navigation, which are used in the market and precisely on the example of such a form we will look at them by entering some classification.

The mechanism from the toy that chaotic chasing the robot on the floor. No sensors.

The toy mechanism works on the principle of “turn when you pretend to obstacle”, no electronics, turn on and off this toy you need manually. No opportunities for building a map of the room, zoning, returning to the base and other intelligent things to speak. Stand these toys from 700.

Plus, we usually have a terminal container presence switch and a coup sensor “on belly”. These two sensors in one or another implementation have more advanced models.

Added IR Sensor of finding the base (it is the central approximation sensor) and the bumper on the terminal switches. There are no encoders on wheels, drives a robot “From the obstacle to the obstacle”, return to the base on IR rays.

Slightly more complex design. Impact bumper is in one or another implementation of all robots vacuum cleaners. Someone has a contact (that is, there are limit switches), someone has a contactless (that is, there is no mechanical movement), but without him the robot will not understand what she crashed somewhere. And it will be cut, because various sensors on the robot can not always “cover” all the space in front of him, they have dead zones and bumper Last chance of a robot to determine the obstacle. But for some vacuum cleaners, this is the only way “to the touch” move.

The bumper is simple: two limit switches and spring-loaded semicircular plates. When the vacuum cleaner strikes the obstacle, depending on its location, both switches are closed or only to the left or right. And the vacuum cleaner “understands”, which crashed into something in front of him or side.

The database is that inexpensive, which is more expensive models, see thanks to the old good IR rays. Two parallel rays form “rails”, for which our vacuum cleaner is trying to “get up” in the end and delight to the trough. But this IR transceiver consisting of a dual infrared LED and receiver can not only perform the function of finding a base, but to play the role of a contactless obstacle sensor so that the robot vacuum cleaner rests on the wall in front of oneself.

The IR sensor can be installed not in the center, but on the sides, but the manufacturers do not rush to the proven technology, and it also allows you to control the vacuum cleaner from a regular IR console.

Therefore, manufacturers recommend to leave on the right and to the left of the base on the meter to one and a half, so that there was a free “entrance” to it, but my robot vacuum cleaner lives calmly in a snack for the sofa and finds the base.

to. p 3. Add encoder. The vacuum cleaner can more accurately work out its position and its turns are already predictable, and the deviation from a straight line is definable. Such a robot will try to ride parallel to the lines of your route and understand what turned to the desired angle. Motor-wheels of vacuum cleaners are supplied with encoders of different types: brushes, resistive, optical, on Hall sensors, and t. P. But the goal is one: determine which angle turned the wheel.

Overview of the best models of robots vacuum cleaners on with building a room map

Gutrend Echo 520

The model we considers equipped with a well-thought-out navigation system of the last generation. Its laser sensors calculate the exact distance to obstacles, so that the robot vacuum cleaner builds a detailed room map.

Progress is yours: How modern robots vacuum cleaners are oriented in space

Robots vacuum cleaners are quickly becoming part of the life, significantly facilitating our life. Every day, more and more models appear, and not only their quantity changes, but also the quality. We’ll figure out how the navigation abilities of smart helpers have changed.

Robots vacuum cleaners are all perfect. Now they know how to fit perfectly in space and make an accurate map of the room. If yesterday, the maximum that the manufacturer could offer is a vacuum cleaner that detects the subject only by facing it, then today the robot does not just bypass an unknown obstacle, but also recognizes in detail the subject and remembers it.

Do not self-medicate! In our articles we collect the latest scientific data and opinions of authoritative health experts. But remember: only a doctor can be diagnosed and prescribed treatment.

Following the path of development of smart navigation, you will share the way and forever, what is the difference between Ladar from SLAM, and you can choose your perfect assistant!

The most first appeared a contact system of navigation, which is also called random. Such a robot recognizes the obstacle only in the event of a collision with him to then move in the opposite direction. These models most often have a soft bumper so that neither the vacuum cleaner nor the subject is injured. With supporting cleaning they cope with adequate. However, the lack of such technology is that the robot inevitably takes the wall for the obstacle to bypass. To solve this problem, the perimeter crawl function is often added.

Robots-vacuum cleaners with system type of navigation perceive the world around the world using advanced algorithms formed. Thus, the robot arrives to the obstacle, “sees” it with the help of infrared sensors or touches the bumper, then changes the trajectory of movement. When, during automatic cleaning, the sensors suggest that the vacuum cleaner moves along the wall, the corresponding algorithm is activated, in which the robot continues to move so that the wall always remains on one side. The “Spot-cleaning” algorithm is included in the absence of obstacles. In this case, the vacuum cleaner moves along the spiral, processing about 2 m² of the area, after which it switches to another square or goes to another algorithm.

The orientation system in space laid in some robots does not allow clashes with objects. Ultrasound and infrared sensors reveal to notice an obstacle within 1 meter. When objects are detected, the program adjusts the trajectory of the movement of the robot vacuum cleaner and takes it to the side. The ultrasonic sensor in the front of the device and infrared sensors on the side surfaces around the perimeter provide the function of circular tracking obstacles, as well as the ability to move around the perimeter of the room along the walls. If the collision has yet happened, the touch sensors installed in the movable bumper enter the game. They send a signal to the central processor, and the one, in turn, promptly adjusts the trajectory of the movement of the robot.

There are also robots vacuum cleaners equipped with a positioning or map constructing system. The basis of its work is the SLAM method (Simultaneous Localization and Mapping). Creating a situational card and localization of an object in space. The scanner installed on the vacuum cleaner checks the space around and on the response of its sensors generates a map. The advantage of this function also is that it allows the robot to build an optimal cleaning algorithm.

G-SLAM Navigation Technology involves building a card using a gyroscope. G-SLAM measures the acceleration and angular vehicle speed, thereby calculating its location. In other words, the robot remembers from where he arrived, where it is sent and the location of the docking station to return to the end of cleaning. Robots with a gyroscope can build a map only in software and display it in the application. At the same time, the card is not saved, you can only be seen online in the application at the time of cleaning.

Building a card via the V-SLAM system occurs through the camera at the top of a smart vacuum cleaner, directed at an angle of 45 degrees ahead and up. V-SLAM-technology simultaneously determines the location of the robot and builds the card. Making a snapshot, compares pixels by contrast. If objects or vacuum cleaners change their position, the device will draw a new card, after which it compare it with the previous one to determine its position in the room. When location is defined, new behaviors are implemented. The robot is able to move in a straight line and go to the docking station at low charge level. Of course, sometimes mapping is complicated by bad lighting or complete darkness. In this case, the robot cannot assemble the correct information about the surrounding space, so it is often lost under the closet or bed, and is also not effective at night when the light is turned off.

Robots-vacuum cleaners equipped with a lidar (laser) or LDS sensor, “see” space, directing to objects laser or light ray. Lidar is located on the upper “turret” device. The sensor contains source and receiver of a laser or light beam (LEDs emitting light flows in the infrared range are used in low-power models). Emitted light beam, meeting with obstacles, is reflected from them and catches a receiver of lidar. LDS sensor revolves around its axis with quite high frequency, providing a circular review. Such robots very accurately simulate the map of the room, so they will not be lost in the apartment with several rooms. You can also adjust the zones of cleaning and create virtual borders that the robot will not cross. Lidar allows vacuum cleaners to very accurately navigate the room, and the user. to flexibly configure the cleaning parameters.

Another way navigation is to build a TOF camera card. This is a new technology that some electronics manufacturers began to introduce, for example, at the beginning of 2022, the model S10 of the brand 360 appeared on the Russian market, which supports this navigation system. A special wide-angle camera allows you to create volumetric snapshots. Otherwise, such cameras are called “depth chambers”. The TOF camera is capable of emitting light rays of infrared Spectra and contains a photosensitive matrix that catches the intensity of reflected light. The principle of operation is similar to the lidar system. The benefits of such a robot are several. First, the level of lighting is no longer a problem, because the sensor forces to “draw” the boundaries of the space even in the twilight. Secondly, the camera is embedded with the upper surface of the robot, which allows you to make it more compact, and, therefore, open it the way to hard-to-reach places.

Irobot technology

The latest IRobot Genius technology, implemented in ROOMBA-Vacuum Robots I and S Robots and Braava Jet M6 robots, provides unlimited opportunities to ensure effective cleaning and carrying out machine learning process of robots. Technology has become the result of 30 years of research and development in the field of robotics.

Robotic assistant is constantly learning during the work, adapting not only under the interior, but also for the tasks supplied by the user. The cleaner can integrate into the smart home system and perform the necessary tasks with a certain frequency.

Braava Jet and Roomba, equipped with an imprint mapping system, determine those zones that need to be cleaned more often than others. The territory under the dining table, near the sofas and near the working area in the kitchen will be cleaned with increased periodicity due to the IRobot Genius technology with machine learning function.

Robots collect information about cleaning and independently determine those temporal intervals when they are required to carry out the cleaning process of flooring. At the same time, the gadgets take into account the introduced restrictions and various prompts coming from the user.

Irobot Genius analyzes the schedule and lifestyle of the owners of the robot, offering personal cleaning schedules. For example, carrying out full cleaning on Mondays, performing local cleaning after breakfast and dinner in the kitchen, garbage collection near the entrance door at a certain time and t.D.

Clear and friendly IRBOT HOME application allows you to quickly create your own home assistant working conditions with the possibility of their subsequent entry. If necessary, quickly go to the pre-installed task and start its execution.

Robots analyze the information received during the cleaning process and independently offer the introduction of various forbidden zones to increase the purification level and reduce the time to guid the ideal order in the house.

ROOMBA and BRAAVA JET now offer to increase the frequency of cleaning, based on various data. Being smarter day by day, gadgets understand when the amount of dust and garbage in the house increases, and also determine the season of pet molts.

An Irobot Home application with implemented IRobot Genius technology received a new inteeis and has become more convenient and understood for the end user. Complex machine learning processes are hidden for the friendly external shell of the software product.

Robots can receive data from sensors and locks included in the smart home system to clean the premises at the moment when there is no one at home. Robotic helpers know exactly what to do, but do not interfere with their masters.

The virtual wall is a small accessory, acting as a ROOMBA robot limiter, which allows the user to introduce forbidden to clean the zone and limit the cleaning area by prohibiting entry into adjoining premises.

The limiter emits an infrared signal invisible by the human eye, but the perceived Roomba. Having captured a ray, emanating from the virtual wall, the robot vacuum cleaner regards it as a barrier and changes the trajectory of movement.

The robot movement limiter is compatible with vacuum cleaners for dry cleaning ROOMBA series 600, 800, 900 and E. In addition, it can be applied with I7 and I7 robots, although these models have support for the input zone through the application.

The universal limiter is powered by a pair of AA batteries (“finger” power supplies) and is designed for functioning in two modes. directional and circular, which makes it possible to use one device to solve various tasks.

When the direction is directed, the beam passes through the front part of the accessory, creating a smooth invisible barrier. Such a mode is used to prohibit the departure of a robotic assistant from the room when installing a virtual wall at the threshold.

With a circular signal, the signal shape is a semicircle, so you can enter a ban on cleaning small areas. Most often this mode is applied to the ban on entering the feeding places of domestic animals, so that the robot does not spill the water destructive for the engine.

All robots-vacuum cleaners for dry cleaning Roomba are equipped with a function of cleaning a small section of the floor covering. The Land of Floral Pot, brought on the shoe of sand or scanned in the kitchen, the cereals require quick and efficient cleaning, which ensures the function of local cleaning.

virtual, wall, robot, vacuum

Local cleaning starts using a button placed on the front panel of the robot. Depending on the model, it is indicated by the inscription SPOT or a pictogram resembling sight or target. Place the Roomba in the Pollution Center and click this button.

At the start of Roomba, it starts to unwind over the helix until it reaches the distance of one meter from the start place. Next, the robot moves in the opposite direction, passing the purified territory again, after which it stops where it was launched.

Features of the function

Construction of the room map is performed in one of two ways:

  • Based on the laser rangefinder data (lidar). turrets with slots located on the lid of the robot vacuum cleaner. The laser emitter installed in the tower scans the surrounding space to 360 and gives the exact coordinates of obstacles entering the horizontal plane of detection.
  • With the help of a survey camcorder. The robot recognizes the walls, ceiling, visual landmarks and, combining this data with indicators of infrared and tactile sensors, recreates a virtual map of the room.

The advantage of a laser rangefinder compared to the camcorder is independence from the illumination of the room. At the same time, Lidar does not notice glass obstacles, reflective surfaces and any objects that do not fall into the scan plane. In this sense, the camera gives a solid and more detailed picture of the environment.

How removes

Removes how and all his counterparts are not bad, cleanliness is maintained in the apartment and, accordingly, the order that the robot does not wind up the headphones, did not suck the nose and T.D. I decided to make a few x5 comparisons with his popular fellow. Unfortunately, with Xiaomi Mi Robot did not have time.

X5 against V7

Look in the room mess.

The robot vacuum cleaner starts cleaning.

After cleaning left only three papers and several risenok, no longer placed in the container.

Although he cleaned after V7, he still found dust and wool.

According to the results of cleaning V7 collected 98.3 grams of garbage, and x5. 75.2 grams.

X5 vs A4

After harvesting, a little rice remained near the rug obstacle and a couple of pieces under the wall.

According to the results of cleaning X5, I collected 95.5 grams of garbage, and A4. 94.6 grams.
