Sweeping robots, also known as automatic sweepers, smart vacuum cleaners, robotic vacuum cleaners, etc., are a type of smart household appliances that can automatically complete floor cleaning in the room with a certain artificial intelligence. Generally speaking, robots that complete cleaning, vacuuming, and wiping are also collectively classified as sweeping robots.
What are the important functions of the sweeping robot?
1. Detection function
(1) Collision model:
Divided into infrared sensor and ultrasonic bionic technology. The infrared transmission distance is long, but it has high requirements for the use environment. When it encounters light-colored or dark-colored household items, it cannot be reflected back, and it is easy to cause accidental collision of the sweeping robot;
(2) Planning model:
It mainly uses the PRS laser navigation technology represented by lefant, which enables the sweeping robot to generate a 360-degree digital map (PRS map) of the room before cleaning, so that the sweeping robot can walk around the edge of the object instead of passing through the object, avoiding In some cases, it turns around in place. The sweeping robot models currently using this technology include the Neato XV series, Neato Botvac series, Vorwerk VR series, etc.; in addition, the lefant Botvac D series is equipped with the commonly used laser sensor "LIDAR" such as self-driving cars, which can be measured by measuring the arrival time of light For distance, the laser for distance measurement is rotated 360 degrees to obtain the surrounding three-dimensional shape.
2. Cleaning (dragging) function
Whether it is a collision-type or a planning-type sweeping robot, the cleaning (dragging) function is the most basic function. However, in the cleaning mode, collision type and planning type sweeping robots are slightly different. Collision-type sweeping robots (drag-sweeping integrated robots) generally have several modes such as whole-house cleaning, side-by-side cleaning, and fixed-point cleaning.
Planning-type sweeping robots are mainly based on two modes: multi-house cleaning and fixed-point cleaning.
3. Automatic recharge function
Automatic recharging is also a basic function that both the current collision type and the planning type have, and it is also one of the intelligent performances. It means that when the battery is insufficient or the cleaning is completed during the cleaning process, the sweeping robot can automatically search for the location of the charging stand and automatically return to charging. At present, the automatic recharging function of the collision model is better than the iRobot Roomba series. The domestically produced Cobos and Emma are weaker. Planning-type sweeping robots such as Neato performed well in various series.
4. Anti-winding, obstacle-crossing, and anti-falling functions
In fact, the anti-entanglement and obstacle-crossing ability mainly reflects the ability of the sweeping robot to escape, and it is also one of its important functions. Anti-entanglement mainly refers to whether the sweeping robot has the function of preventing entanglement when it encounters items that are prone to entanglement, such as carpet tassels, hanging curtains, and wires. Obstacle crossing mainly refers to the ability to pass through the barrier between rooms, such as Slightly raised ground partitions, gates, etc. The anti-fall function is to install a cliff sensor at the bottom of the sweeping robot to prevent the sweeping robot from falling. (Such as duplex stairs)
5. Virtual wall function
The virtual wall, as its name implies, is a device that makes a false wall, and is a device that can control the sweeping robot to work in a spatial area. It is a common auxiliary device for collision-type sweeping robots. Of course, planning-type sweeping robots will also be equipped with virtual walls. The main difference between collision-type and planning-type virtual walls is that collision-type virtual walls generally need to be powered on, while planning-type virtual walls are mostly based on magnetic strips and do not need to be powered on.
