In order to adapt to the market environment of the spread of lazy cancer, the market of sweeping robots is expected to expand to 4.34 billion dollars in 2023, with an annual compound growth rate of more than 16%. However, even in domestic coastal cities, the penetration rate is only 5%, and most potential users are still in a state of onlooking (including the author).
Many people may think that the sweeping robot is too slow to work. It is either stuck in a corner or damaged something. It may even change the "landscape" of the home. It is better to do it yourself. But like the washing machine, the machine may not be good, but it can free up time and liberate users. When the robot technology is mature, "fattening" can be bought.
If we say that at the beginning of the year, the Kvos T8 AIVI let us see how high the ceiling of the fourth generation sweeping robot can be; The 2699 Covos T8 shows us how practical the fourth generation sweeping robot can be.
T8's product force is all invested in upgrading the three core functions of "anti-collision winding, drawing construction and sweeping". Structured light obstacle avoidance, millimeter level dToF navigation and vibrating water tank drag make the Kvos T8 different from the sweeping robot we have played before.
appearance
The color matching of the pandas in the Coworth T8 is very pleasing, and the top surface is white, which is clean. The side and bottom that are easy to get dusty are black and easy to take care of.
The lidar top cover and nameplate are both in rose gold color, which is low-key. The fuselage is made of solid materials, which are of great weight, exquisite but not lacking in leather.
The dToF lidar has a unified enclosure, which is not easy to enter ash or water, and is also a good way to take care of. You can see the random knives and brushes when you open the cover, and you don't need to turn over the packaging when you need them urgently.
Obstacle Avoidance: Zero Collision, Redemption of "Pie Husky"
Obstacle avoidance ability is the premise of whether the sweeping robot can be used. In the past, the sweeping robot used collision to "perceive the environment", unable to recognize obstacles, often ran around with shoes and boxes, and often swallowed various pieces of objects on the ground, even power lines, so it was called "pie husky".
Compared with its big brother T8 AIVI, the largest difference between the Kvos T8 and its big brother T8 AIVI is that the front is changed into a 3D structured light sensor. It is the first sweeping robot that adopts structured light obstacle avoidance and millimeter level dToF navigation, coupled with self-developed TrueDetect ™ 3D perception and TrueMapping ™ Global planning technology enables the Kvos T8 to predict the height, width and distance of the space, measure the size and size of obstacles in front, and effectively avoid collision.
The camera can capture the light of the sensor
Compared with the binocular vision sensor, the 3D environment sensing sensor is more expensive, but it is not affected by the ambient light, and can accurately obtain the 3D point cloud data of objects. With dToF navigation, the reliability of map building and obstacle avoidance is better. The most exaggerated thing is that the object perception accuracy of the Coworth T8 has increased by 10 times to 1mm, which sounds very advanced.
But no matter how advanced it is, it depends on the actual curative effect and whether it can poke the pain points actually used. We carried out collision, winding, jamming and obstacle surmounting tests for indoor obstacles that we often encounter in daily "pie huskies". In order to test the safety of items, we removed the brush before the test:
The primary items are thin feet and books. It's not a problem at all. When it comes to round small stool legs, the Coworth T8 can stick around and make a circle.
The intermediate project is curtain tassel and power cord. Normal sweeping robots are likely to have the embarrassment of swallowing the thread card when encountering them. It is expected that there will be no problem with tassels, but the ability to deal with small power lines is the ability of sweeping machine talents in the past year or two. Both of them have no pressure on the Covance T8.
The optical structure is easy to misjudge the transparent material, so in the advanced test project, we used a toothbrush made of translucent material, and the result was OK. And the most unexpected is the TrueDetect of Coworth T8 ™ The 3D perception system can even avoid earplugs, which are orange earplugs on the wooden floor. The sweeping robot in 2020 has been so advanced. Indeed, science and technology is the first productive force.
The point in the middle of the picture is a 3M earplug
There is no need to worry about the greedy "pie husky" swallowing my noble C to L line, and the toys, building blocks, and rotten glue (Goddard model) parts dropped on the ground will no longer be sacrificed innocently.
This is a flexible "pie husky"
Within a week of testing, not only did it not swallow thread, but also it did not get stuck under the sofa like the old product. Even if it has the ability to cross the threshold of 2cm, it also appears to be cautious when going up and down the threshold. It never happens again that the threshold is jammed or the carpet is jammed.
Planning and mapping: stunned! Modeling precision!
The workflow of Covance T8 is to circle around the space and then "scan line by line". In the new environment, you will first scan the front for a few seconds, and then run forward. When encountering obstacles, you will walk around it for half a circle, return to the original direction, and then run forward.
Millimeter level dToF navigation plus TrueMapping carried by the Coworth T8 ™ Global planning, claiming that the perception distance of 10 meters can be achieved. In the pre construction phase, it pauses for about 3 seconds to scan out the regional sketch of about 50 degrees. If you forget to close the door and let it sweep, you can even sweep the area to the garden in front of the door.
In actual test, it can detect the bench and table with thin feet far away, and even can see the wall seam less than two fingers wide next to the refrigerator (you can even use its construction drawing to measure the size and area of every corner). Basically, as long as one long side is completed, the house type diagram is very complete, and then only fine adjustment is made to correct the position and number of table feet, stool feet and sundries.
The fineness of the drawing, the position of slippers, stool feet and table feet were identified, and even the scattered wires and toys used for testing on the ground appeared on them. wow awesome。
In addition to the geographical fence/restricted area and the function of merging and splitting partitions, this time there is a multi-layer map. Loft or duplex villas do not need to rebuild the map. In fact, it can work well without an app with the help of breakpoint scanning and automatic relocation.
Sweeping and mopping the floor: finally, there is a robot that cleans the floor carefully
New technologies such as obstacle avoidance and mapping are responsible for not blocking, not blocking, not missing, and the rest is the sweeping and mopping of the shop floor.
In the default standard suction mode (with two gears upward), the cleaning system called Blue Whale in Kovos will not leave any trace whether it is paper scraps or small clay sand. For the products of large factories in 2020, it seems that the pressure of these daily operations is too low.
It's the room that I think is clean. When I went to Covance T8, the dust box was filled with dust. The bed and sofa bottoms that I can't touch at ordinary times really need a sweeping robot.
480 high-frequency vibrations per minute
Finally, the most special "high-frequency drag" function is solemnly introduced. After using this function, I can't help thinking that the function of wiping floating dust in the past should also be called "mopping"?
Super strong tea with granules
Stubborn stains in batter state
This high-frequency scrubbing system, called OZMO Pro, has a very violent principle. The giant motor controlled duster bracket that is attached to the water tank is forced to mop the ground repeatedly at a high frequency of up to 480 times per minute. It is the first time to encounter such a robot that simulates human hands mopping the floor. The actual effect is still very fierce. The Coke and coffee stains that were killed years ago disappeared after the Kevos T8 passed by. The system also has a fine drag mode, which can be cleaned twice at the same position.
It is estimated that there is no opponent in the market for this mopping ability. Although this mode is a bit noisy, robots work during working hours anyway, which is hard to hear at ordinary times. It is true to wipe the floor clean.
summary
It doesn't matter if you can't understand a lot of coooooooool sounding technologies of the machine, because from the actual test, they are all implemented, and even inject soul into T8.
One thing to say is that once the intelligence and functions are in place, the experience of using the Kvos T8 is quite indifferent. The sweeping robot suddenly becomes very "rough and crude". You don't need to take care of it. It won't get stuck on the edge of the cabinet or carpet, nor will it touch anything on the ground. How was your home before you went out and how was it when you came back, but the ground has been cleaned.
Know that you can avoid all obstacles and really mop the floor. These two historic advances alone make the price of the Kvos T8 look very good. If 618 accidentally subsidizes the platform again, wouldn't it be nice?
