The advancement of intelligent technology has brought a new experience to our life. Many traditional tools have undergone earth-shaking changes after being equipped with intelligent technology. Products that were not optimistic have become indispensable products in our lives. . The early sweeping robots were not efficient in cleaning efficiency and intelligent technology, so they were suspected by many people. However, with the advancement of technology, sweeping robots have already broken through obstacles, and sweeping robots have become the most popular in the wave of intelligence. One of the welcome smart cleaning tools.
Technical framework of sweeping robot: two dimensions Construct the technical framework of sweeping robot from two dimensions of information chain and technical module: one is the logical analysis of information input, decision-making to output, and the other is the principle analysis of system, module, hardware and software.
perception system is the receptor for the autonomous floor cleaning robot 's information input, essentially digitizing the surrounding physical environment. More specifically, the digitization of the home's indoor environment. From the module point of view, it mainly includes three parts: ranging, identification, and detection; from the component point of view, it mainly includes sensors and edge algorithms. The decision-making system is responsible for information processing and transmission, and its essence is the intelligent processing of digital information. From the module point of view, it includes navigation, obstacle avoidance and control. From the perspective of components, software (intelligent algorithm) has higher barriers than hardware (PCB+chip). The execution system is responsible for the implementation of intelligent decision-making. From the perspective of modules, it mainly includes three parts: cleaning, moving and battery life. From the perspective of components, the execution system is more focused on hardware, and the mechanism design capability of software depends on experience accumulation
The principle of the three detection and sensing systems of the sweeping robot , there are many labels on home appliances in modern life, among which "intelligence" is an essential keyword . In recent years, more and more smart home appliances have entered our eyes, such as smart TVs, smart refrigerators, smart washing machines, smart sweepers and so on. As one of the more mature smart home appliances at this stage, the smart sweeping robot saves lazy people a lot of cleaning time. In fact, the sweeping robot has developed to this day, and its intelligence not only depends on the developer's programming chip, but also benefits from its detection and sensing system. Today, let's take a look at the detection of the intelligent sweeping robot. What is the mystery of the induction system. The intelligent sweeping robot is a kind of artificial intelligence, and the detection and sensing system enables the sweeping machine to have the ability to perceive the environment, and can avoid obstacles well, so that the service life of the machine is guaranteed.

Infrared Detection System

In terms of detection and positioning systems, infrared detection and bionic ultrasonic detection are most widely used by commercial floor cleaning robot . The infrared detection system mainly uses the principle of infrared light sensing, and infrared radiation can detect the surface of the material. The infrared detection component can convert infrared light signals into electrical signals, and then determine the placement of objects in the environment, so that the sweeping robot can perceive the environment. The infrared detection system is mainly adopted by many manufacturers. In the past, it had the advantage of lower cost, but it also had disadvantages such as low accuracy and inability to distinguish black objects. But now, a new generation of RPS laser ranging system has been launched. After scanning the room 360 degrees through the "laser eye" on the top of the sweeper, a map is generated, and navigation is improved according to the map.

Bionic Ultrasonic Detection System

The principle of another bionic ultrasonic detection system is to use the sound wave detection function similar to that of dolphins and bats, and use the known propagation speed of ultrasonic waves in the air to measure the time it takes for sound waves to reflect back when encountering obstacles after being emitted. Calculate the actual distance from the transmitting point to the obstacle according to the time difference between transmitting and receiving. The bionic ultrasonic detection system is mainly used by iRobot and Proscenic. The cost of the bionic ultrasonic detection system is relatively high, but the resolution of black objects and transparent objects is more accurate.

A new generation of detection system - double detection device

We all know that the cost of the bionic ultrasonic detection system is high, but the resolution of black objects and transparent objects is relatively accurate; while the infrared detection system is relatively low in cost, but it also has shortcomings such as low accuracy and inability to distinguish black objects. . The detection system can help the intelligent sweeping robot perceive objects in the home environment, and assist the sweeping robot to compose the home environment. The effect reflected in the use of the product is: cleaning is more regular, reducing collisions with household items, which can not only ensure that the sweeping robot is not damaged, but also reduce the possibility of damage to the household, so that you can use the product with confidence.
Navigation is the main line of commercial floor cleaning robot technology innovation: it has gone through three stages of random collision-local planning-global planning, from disorder-order-intelligence. Navigation is a system integrating software and hardware. Among them, navigation algorithms and navigation sensors are the core technologies of sweeping robots; at this stage, chips are universal and not the key to current competition. Cleaning is a branch line of technological innovation: the innovation path of cleaning technology corresponds to the four traditional cleaning links of sweeping, mopping, washing and pouring in China. Sweeping robots essentially solve two levels of cleaning pain points. One is to initially realize cleaning automation, emphasizing the breadth of automated cleaning, so that automation can cover four cleaning links. The second is to fully realize cleaning automation, emphasizing the depth of automatic cleaning, completely freeing hands, and eliminating the need for manual re-scanning.
In the short term, high intelligence and deep cleaning are the two essential attributes of ideal products for cleaning appliances. Given that the current sweeping robots have basically met the needs of intelligent cleaning and shallow cleaning, the pain point of consumer demand has shifted from cleaning intelligence to cleaning depth. In the long run, sweeping robots are expected to move from single functional intelligence to multi-scenario intelligence. Interactive upgrading is the development direction of technology, and recognition ability and AI computing power will become the next breakthrough.
