Sweeping robot obstacle sensing system optimal solution: infrared or bionic ultrasonic
What is an obstacle sensing system? When we observe the sweeping robot products on the market, we will see that the crash barrier is wrapped in a strip. This is the obstacle sensing system of the sweeping robot. The main function of the system is to sense the obstacles in front of the sweeping robot and slow down the fuselage. The speed reduces the impact force to achieve the function of protecting itself and the object being hit. The two commonly used sensing systems are infrared and bionic ultrasonic waves. This article will conduct a comparative analysis of the two sensing systems in various aspects, so that everyone can understand their respective advantages and disadvantages.
Who is more accurate?
A sweeping robot equipped with an infrared obstacle sensing system, the infrared rays emitted from the front of the fuselage are echoed, and the infrared receiver in the fuselage receives the infrared reflected wave and positions the space. The bionic ultrasonic obstacle sensing system uses aviation industry technology and built-in bionic ultrasonic detecting sensors. For example, the Proscenic Pro-COCO sweeping robot from Taiwan exports to Japan is a bionic ultrasonic system, which is like a whale during operation. Like bats, the bats emit super-wave detection trajectories, effectively avoiding collision with household items. It is the technical application of aviation industry technology in the field of household cleaning, which is more advanced and accurate than infrared. Therefore, in terms of positioning, ultrasonic detection wins by detecting the advantages of large thickness, high sensitivity, and more accurate positioning.
Whose mitigation/collision-free system is more optimized?
When a sweeping robot equipped with an infrared obstacle sensing system encounters a transparent obstacle, the infrared light emitted by the infrared LED will directly pass through the transparent object itself without generating any echo, so the sweeping robot of the sensing system cannot sense it. The presence of transparent and dark objects such as fish tanks and floor-standing glass doors. That is to say, the infrared connection of the sweeping robot cannot sense the obstacle in front and thus cannot automatically decelerate and buffer the collision. In comparison, coco's bionic ultrasonic wave sensing system can clearly detect a variety of household objects. When it is sensed that there is an object in front, the robot will decelerate by itself, avoiding direct collision between the machine and furniture items, safety and security. Therefore, in the buffer/collision avoidance of the system, the bionic ultrasonic wave sensing system still has significant advantages.
Who is more clean?
A sweeping robot equipped with an infrared obstacle sensing system, dust can easily block the infrared sensing port, affecting the detection of infrared rays, causing problems such as unclear positioning of dust and high false positive rate in hard-hit areas, so it is easy to omit dust during cleaning. The cleaning is not thorough. The bionic ultrasonic wave sensing system judges the cleanliness of the ground by the inhalation of the amount of garbage, and automatically enters the spiral cleaning mode in the dust-hit area until the area is thoroughly cleaned, including the corners of the furniture. Therefore, in terms of cleaning power, the bionic super-wave sensing system still has no suspense to win.
In summary,
At present, the sweeping robot using the infrared obstacle sensing system still has some shortcomings or shortcomings, but with the development of science and technology, the requirements for smart household products will become higher and higher in the future. In comparison, the bionic ultrasonic wave sensing system is more comprehensive and convenient for the protection of the furniture and the sweeping robot itself, and plays a decisive role in the daily use of consumers.
