This weekend, 360 will usher in the first market delivery of its 2021 flagship sweeper, the X100 Max, and judging from the first round of pre-sales, this top-of-the-line machine with ultrasonic automatic and precise carpet recognition has been quite well received by the market.
The same in the smart home track competition stone technology, in CES 2021 released the latest stone sweeping robot S7, the first time to increase the ultrasonic automatic carpet recognition technology, while using sonic vibration mopping.
360 and stone technology's 2021 flagship sweeping robot are equipped with ultrasonic technology for carpet recognition, foreshadowing the ultrasonic material recognition technology will become the future of sweeping robot standard?
Sweeping robots, as a popular intelligent home service robot, help people reduce cleaning work to a certain extent, but not perfect. For example, the carpet cleaning problem, shag carpet, dark carpet on the garbage masking strong, tiny particles, hair, etc. fell in the carpet is difficult to see through the naked eye, cleaning time-consuming and laborious, is nowadays home cleaning in the difficult point. The application of ultrasonic material recognition technology in sweeping robots is precisely to help people free themselves from the trouble of cleaning carpets, and provide information perception support for sweeping robots to expand the depth of carpet cleaning.
Using the characteristics of ultrasonic waves that are not affected by light and color, the ultrasonic material recognition technology uses a 300KHz high-frequency sensor, based on the TOF measurement principle, using different materials with different absorption capacity for sound waves, and distinguishing different materials through echo detection technology, so as to accurately identify the materials of carpets, floors and other materials, and to achieve the purpose of dictating that the sweeping robot starts the correct cleaning mode.
High-frequency ultrasonic sensor
The high-frequency ultrasonic sensor independently developed by AUDIOWELL uses 300KHz high-frequency ultrasonic waves and adopts special coupling materials to send the ultrasonic waves into the air, which is mainly used for high-precision detection in close range. The high-frequency ultrasonic sensor equipped in the sweeping robot has the function of accurately identifying materials and realizing the dual-use function of material identification and cliff detection in parallel.
Accurate Material Recognition
Through echo detection technology and TOF measurement technology, the high-frequency ultrasonic sensor can accurately recognize the floor and carpet, and combined with the algorithm of the main body of the sweeping robot, it establishes a multi-mode parallel cleaning system.
Realize dual-use
High-frequency ultrasonic sensors used in sweeping robots can realize the dual-use function of material identification and cliff detection in parallel, providing more room for improvement in optimizing the internal structure of the robot and reducing the weight of the product.
With the economic development of the international community, the industry and consumption related to household carpets will continue to increase. In recent years, the sales of household carpets in China's coastal cities have increased rapidly and radiated to the inland cities at a fast speed; the United States, Britain, Switzerland, Germany, Belgium and other countries are developed countries on the carpet consumption demand remains at a high level, of which the United States of America's household carpets accounted for more than 60% of the country's total sales of carpets. Equipped with ultrasonic carpet recognition technology, can deeply clean the carpet sweeping robot market potential is unlimited, will become one of the smart home cleaning mainstream products. In the near future, ultrasonic material recognition technology may thus shine.
