4Common problem

Do sweeping robots know how to choose? A lot of people don't know.

For young people nowadays, life is under great pressure, work is getting busy, and home becomes a place to sleep, and there is no time to take care of family hygiene. It is expensive and unreasonable to ask a nanny. Therefore, sweeping robots have become the first choice of many young people. In the market, there are many brands of laser navigation sweeping and mopping robot with different functions and shapes. Many consumers don't know how to choose sweeping robots. Today, I will explain to you the classification of sweeping robots.

1. Classification according to the guidance method:

According to the guidance method, sweeping robots can be divided into three categories: sweeping robots with gyroscope navigation, sweeping robots with laser navigation, and sweeping robots with vision navigation.

For the planned laser navigation sweeping and mopping robot, it is necessary to solve the problems of where I am, where I am going, how I am going, etc. This requires the use of SLAM (Simultaneous Localization and Mapping), which is positioning and map construction technology. There are three ways to implement SLAM: gyroscope navigation, laser navigation or visual navigation.

Gyro navigation is to rely on sensors such as gyroscopes and accelerometers to obtain information such as position and speed. It is widely used in defense fields such as aircraft, missiles, ships, submarines, tanks, etc. However, with the reduction of costs and the growth of demand, it is now Expanded to the field of sweeping robots and became the favorite of thousand yuan models.

Affected by the accuracy of the device, there are errors in the gyroscope navigation process, and over time, the errors will continue to accumulate. In a large and complex ground environment, the drawbacks of gyroscope navigation will gradually appear, and it is not well qualified for planning. Cleaning task.

Laser navigation uses the laser transmitter and receiver installed above the sweeping robot to measure the distance between the equipment and the environment to achieve positioning. The positioning is more accurate, but there are also shortcomings in the specific use process.

This kind of positioning system has a flaw, that is, it cannot detect high-reflectivity objects such as floor-to-ceiling windows, floor-to-ceiling mirrors, vases, etc., because the laser hits such objects and cannot receive scattered light; in addition, in order to ensure that new data is obtained, the laser is rotated 360° The probe must be rotated all the time, as a result, the product life will be shortened, and the laser head may be broken in less than a year...

Only at this stage is it impossible to identify and detect high-reflectivity objects such as floor-to-ceiling windows, floor-to-ceiling mirrors, and vases. Some sweeping robots have solved this problem through hardware functions such as glass detection sensors and ultrasonic sensors. So everyone should be optimistic in advance when buying.

Visual navigation is also called vSLAM. The sweeping robot equipped with this positioning system will have a camera on the top. Through a complex algorithm, the robot can perform positioning by perceiving optical images composed of light spots with different brightness. These optical images look different from different angles. By continuously collecting the image information, the robot can locate on the map built by itself, so as to know which positions have been scanned and which places need to be cleaned. However, for low-end visual navigation robots, the camera should only play a role in assisting positioning, mainly relying on lasers or gyroscopes.

2. Classified by sweep and drag function:

According to whether there is a mopping function, the sweeping robot can be divided into an integrated sweeping and dragging and a separate sweeping and dragging robot. So which one is better?

The sweeping and dragging integrated robot has a more comprehensive function, but the sweeping and dragging robot should be a compromise product category. The programming design of the product has both floor support and cleaning. As the saying goes, the cleaning potential of the sweeping and dragging separate robot is better. .

What are the disadvantages of the robot that separates the sweep and drag? First of all, I will calculate an account for everyone. The price of a general sweeper is around 1,000-5,000 yuan, and less than 2,000 yuan is a more popular price. If you buy a sweeping and wiping kit, the price is around 4,000. In addition, the two machines are separated, sweeping and then dragging, it takes twice as much time, and the use of two separate machines is also inconvenient.

So, is it better to sweep and mop? Or is it better to separate the sweep and mop? I think the different cleaning methods for this are all advantages and disadvantages. If the house is dusty and the house is big enough, it is more suitable to separate sweeping and mopping, which can ensure deep cleaning; if you want to save cost, time and space, The cleaning and traction integrated robot is more suitable for you. As for the difference between good and bad, there is no clear dividing line, only suitable and unsuitable.

Now there are more and more types of sweeping robots on the market, with more and more complete functions. Will you choose a favorite sweeping machine to take home?
