With the popularity of smart homes, more and more families are beginning to appear in the role of sweeping robots. However, with the sweeping robot, you really don't have to sweep the floor?
Recently, the China Consumers Association conducted a comparative test on 20 sweeping robot products sold in the market. By testing the key items such as the safety of the prototype and the cleaning effect, the sweeping robot is “numberedâ€.
In this test, the cleaning ability of the sweeping robot was significantly different, up to 93.34%, as low as 29.63%. According to Mei Xiaochun, assistant to the president of China Household Electrical Appliances Research Institute, the coverage rate is affected by the path planning of the sweeping robot. With the development of the industry, the sweeping robot has gradually changed from the random collision mode to the path planning mode, but the functional integrity remains. Staggered.
The cleaning ability of the sweeping robot mainly depends on the coverage and cleaning rate. Coverage is the possibility of sweeping during the cleaning process. It is an important indicator to judge the level of intelligence of a sweeping robot. "Clean coverage is the premise of the clean rate, and the two complement each other." Mei Xiaochun said.
“The advantage of random collisions is that they can be randomly repeated to sweep the previously swept locations to ensure the final cleaning effect, but it takes a relatively long time. Path planning usually uses the 'simultaneous positioning and map construction' technique (hereinafter referred to as SLAM), the machine Know where you are, know how the surrounding environment is, and then learn how to act on your own initiative." Mei Xiaochun explained. According to him, the current sweeping robot SLAM system has two forms of laser radar and visual recognition, and the latter is prone to recognition bias in a dark environment. The algorithm is good, the coverage rate is high, and the coverage is high. Then look at the dust removal ability, which represents the development trend of the intelligent robot.
Consumer demand for intelligent home appliances has increased year by year, and smart home appliances such as smart sweeping robots have entered the homes of ordinary people. However, most of the current domestic quality inspections of sweeping robots only do 3C compulsory certification projects.
At present, although the national and industry standards for the performance testing methods of sweeping robots have been formulated, they are limited to the quality or not, and there is no quantitative requirement for product quality. This is still different from the national requirements for product quality upgrade.
In addition, when buying, you should also pay attention to the direction of the air outlet of the machine to avoid the secondary pollution caused by the blowing of the ground; the filter screen, the side brush and the roller brush are all consumables. Know the usage period before purchase to avoid the follow-up cost too high. "The sweeping robot can't completely clean every corner of the house, so you don't have to buy a sweeping robot to get a broom." Mei Xiaochun said with a smile.
Conductive slip rings are one of the most popular types of electrical connectors. They consist of an insulating sleeve enclosing two metal contacts, with a small gap between them. When current is applied to the ring, it creates resistance between the contacts, which can be used to form a continuous circuit. They can be used in a wide range of applications, such as medical equipment, robotics, aerospace systems, and more. The construction of a conductive slip ring typically consists of two rotors (or rings), with each one containing a number of stationary contacts. When the rings rotate, the contacts move past each other and create an electrical connection.
In today's increasingly electronic world, the need for efficient and reliable power transmission is more important than ever. That's why more and more businesses are turning to slip rings as a means of transmitting power in a variety of applications. Slip rings are electrical connectors that allow current to flow continuously through a rotating assembly, making them ideal for use in devices that require uninterrupted power transmission, such as motors, generators, and wind turbines.
