Due to the limitation of navigation planning technology, the coverage and obstacle avoidance effect of the early robot vacuum are not satisfactory. However, in recent years, with the change and popularization of laser navigation technology of the sweeper, the coverage rate of the main robot vacuum has been significantly improved. Some flag ship models can almost achieve zero error collision. The robot vacuum has a good effect on hair, dust and dust The cleaning effect of debris is much better than manual cleaning.
When many friends choose and buy a robot vacuum, the most distressed thing is that the parameters of the sweeper and the corresponding different configurations of different models. Facing the specific parameters of the robot vacuum such as navigation planning, sensor configuration, route algorithm and obstacle avoidance, the only parameters that can be understood are suction. It is assumed that the greater the suction force is, the better the cleaning effect is, So blindly pursue the big suction, and the result of the purchase of suction cleaning effect is very poor IQ tax products.
Here we will take you to understand the parameters that are often seen by the robot. In order to understand, we will not explore the technical principle behind the parameters, but only discuss the influence of different parameter configuration on the actual use of the sweeper.
Generally speaking, we need to pay attention to several parameters when we choose and buy sweeper robot: navigation and route planning, obstacle avoidance, suction, cleaning and dragging.
Navigation function and route planning algorithm are the most important configuration parameters of the robot. The former is equivalent to the "eyes" of the robot, which determines the accuracy of the map building and the effect of avoiding obstacles; The latter is equivalent to the brain of the robot, which determines the coverage of the sweeper.
Even with the same hardware configuration, the navigation sensitivity and route planning intelligence of different brands of sweeper robot are still very different.
The common navigation planning methods of robot vacuum include gyroscope navigation (random planning), visual navigation planning and LDS laser planning. The planning accuracy and sensitivity are from high to low: LDS Laser Navigation > Visual Navigation > gyroscope navigation.
These three navigation planning methods are very different, and can be distinguished only from appearance.
DS laser navigation plan is to scan the surrounding environment by laser ranging induction, and the floor robot vacuum with LDS laser navigation will have cylindrical bulge on top, and the fuselage height is about 9-10cm:
Visual navigation is to perceive the current cleaning environment by the real-time image information obtained by the camera (visual sensor). The floor robot vacuum with visual navigation plan is flat or with small grooves on the top. The visual sensor is generally located in the concave part of the set-top, and the height of the fuselage is about 7-9cm
Gyroscope planning, as the name implies, is to use the gyroscope built-in of the robot vacuum to sense the position of the sweeping robot. The sweeping robot, which adopts gyroscope navigation planning, has flat top and no visual sensor. The height of the fuselage is generally below 9cm.
As the name implies, obstacle avoidance is the algorithm and technology of the robot to quickly make the avoidance path after the obstacle is identified. This indicator will be described officially on the commodity details page.
There are two main ways to avoid obstacles in the market products: AI visual obstacle avoidance by capturing 3D and distance information of objects in front of the camera and 3D structured light avoidance by using structural light to detect the obstacles in front of the market in real time, which has better obstacle avoidance effect.
The suction force (PA) of the robot is equivalent to the strength of human sweeping. The higher the suction force, the stronger the cleaning force is naturally, but it is not that the greater the suction, the better the actual cleaning effect. Generally speaking, the suction force of 1500-2500pa can meet the needs of indoor cleaning. If the suction is excessive, it will reduce the endurance of the sweeper robot and increase the working noise.
The process of cleaning the ground by the robot vacuum is divided into two parts: one is brush, that is, the edge brush gathers the garbage, the other is to suck, namely, the bottom roll brush + suction port to collect the garbage). Among them, there are three common cleaning methods for sweeping robots: roll brush, pure suction port and combined brush represented by iRobot:
The roller brush type has suction port + bottom main brush (floating brush cleaning effect is the best), which is suitable for cleaning ordinary waste;
The pure suction has only a single suction port, although it can avoid hair winding and hard material jam, the cleaning force is insufficient;
The combination brush is composed of two brush + suction port, which is suitable for hair cleaning, and the disadvantage is that the brush is easy to wear.
Here, it is a great component of the robot - edge brush, which directly affects the cleaning effect of the robot on the corner and debris. The side brush is divided into one side brush and two-sided brush. The two side brush has better effect of gathering garbage, and the single brush is easier to blow debris.
There are some cleaning robots with the function of dragging the ground, which can be divided into a sweeping and towing machine and a ground cleaning robot. The former can clean the ground while taking into account the function of dragging the ground, while the latter can only mop the ground and cannot clean. When buying such a robot, it also needs to pay attention to its way of dragging.
Most of the sweeping and towing machines on the market, the main parts involved in the mop are two: one set of mop bracket with washable mop (or disposable MOP) and a set of water tank.
