How Does a Robot Vacuum Cleaner Work?


A robot vacuum cleaner is the vacuum cleaner that uses motors, sensors and AI algorithms to implement route planning, obstacle avoidance, automatic cleaning and other functions. The sweeping robot has changed the traditional manual cleaning method and can truly free your hands. Due to its convenience, it is deeply loved by consumers.


Core Functions and Components of Sweeping Robots


The sweeping robot is equipped with more than a dozen sensors, such as lidar sensors, gyroscopes, accelerometers, cliff sensors, fan speed sensors, recharge alignment sensors, etc.,to meet the different behavioral requirements. The implementation of each behavior involves the AI algorithm chip. Therefore, robot stability is closely related to hardware and software algorithms.


1. Navigation and Path Planning

Common navigation methods: LDS lidar, visual navigation, gyroscope navigation, random navigation.


LDS laser navigation: the most popular one currently on the market, which uses a lidar sensor to continuously emit and receive laser light to obtain the distance of surrounding objects.The AI algorithm processes the information and builds a room map, Finally algorithm intelligently plans the cleaning route. LDS laser navigation is fast, high accuracy, stable performance, low environmental requirements, and is widely used in vacuum robots.


Visual navigation: Positioning and mapping through cameras are slower than LDS lidar and require high ambient light. However, the robot body is relatively thin and can also expand image recognition.


Gyro navigation: The body is equipped with an accelerometer and gyroscope sensors. It builds a room map through collision. It has low accuracy and low cost, can realize local path planning.


Random navigation: The robot cleans randomly and has no position or composition functions. It has a low cleaning efficiency and a poor cleaning performance, but the price is low.


Navigation effect: LDS>visual navigation>gyro navigation>random navigation


2. Avoid Obstacles

Common obstacle avoidance sensors: collision sensors, infrared sensors, vision, 3DtoF, etc. In order to avoid obstacles better, vacuum robots are generally equipped with various types of obstacle avoidance sensors, such as a combination of collision sensors and infrared sensors to identify obstacles, or a visual camera to identify the type and size of obstacles, and use Tof to assist Improve obstacle avoidance accuracy, etc.


3. Cleaning Capabilities

Components related to cleaning capabilities are: fan, roller brush, side brush, mop.


Side brush: at the edge of the robot, it can collect garbage.


Rolling brush: at the bottom of the robot, it can sweep the garbage to the suction port.


Common roller brush types: full silicone roller brush, integrated rubber bristles, and velvet brushes.


Fan: The robot sucks garbage into the dust box through the rotation of the fan, so the speed of the fan will affect the suction power.

Mop: rotating type, sticky type, etc.


How to choose a robot manufacturer?

1. Product Competitiveness

When choosing a robot, you need to consider the product advantages. You can see whether it meets market demand from the aspects of product function and price.


2. Factory R&D and Customization Capabilities

Robots are the high-tech driven home appliances that involve the R&D of hardware, software, algorithms, and structures. It depends on whether the manufacturer has a professional R&D team and whether it can adjust product solutions to meet brand needs.


3. Quality Control

Whether there is a complete quality management system to ensure product quality.


4. Delivery Time

The factory's production capacity and schedule, and whether it can be delivered at the agreed time.


5. After-sales Service

Perfect after-sales system and timely response speed.
