After school on the afternoon of December 10, 2021, Sanmenxia City No. 1 Primary School invited volunteers from the Henan branch of Beijing BooCax Robotics Co., Ltd. to carry out carpet-style elimination of student activity areas such as school classrooms and corridors. School students, teachers and staff have started the "escort" mode.
The disinfection robots stationed in the No. 1 Primary School in Sanmenxia this time are autonomous mobile hydrogen peroxide gasification and atomization disinfection machines. They are also the intelligent disinfection robots that Beijing BooCax Technology Co., Ltd. once assisted in the fight against the epidemic in Hubei.
According to the placement of classroom desks and chairs, the staff uses the tablet to set the walking route of the intelligent disinfection robot, and then mixes the disinfectant according to the volume of the classroom, closes the doors and windows after debugging, presses the start button outdoors, and the indoor intelligent robot is ready Start disinfection of air and surface.
The verification engineer introduced: “These robots use high-frequency atomization of 8% hydrogen peroxide into ultrafine particles smaller than 10 microns on average. Using the characteristics of Brown’s principle, the disinfectant particles will be scattered in every corner of the space to wrap the germs. The microorganisms are inactivated to achieve the disinfection effect.
This disinfection robot is 1.4 meters tall, has a chubby "little belly" on the round chassis, and a "small fan" on its long neck. It moves at a speed of 0.3 meters per second while spraying outwards. The mist disinfectant is used for disinfection operations. The disinfection robot can load 16 liters of disinfection water at a time, and spray the medicine through the four-way nozzle on the head. The disinfection area can reach 36 square meters in one minute. A single robot can cover more than 1000 square meters at most, and the battery life is 4 hours to 5 hours.
This is an intelligent robot that does not need to be driven manually. As long as the route is programmed in advance, it will follow the route for detailed killing, and it can also be remotely controlled. Regardless of its small size, most of the outdoor killing work must be done by it. Moreover, the robot kills for a short distance downwards, which will not cause harm to human health, and also eliminates the hidden danger of infection caused by the gathering of people, making the killing process more efficient and safer.
The person in charge of robot procurement at Sanmenxia First Primary School mentioned: “There are 6 floors in the elementary school, and 8 atomizing disinfection robots BKS-ST-180C are currently purchased, combined with the disinfection log function of the disinfection robot APP, to arrange 3 disinfection tasks a day , The daily disinfection is arranged at 8 am before class, after 11:30 at noon, and again after school at 5:30.
The atomizing disinfection robot ‘patrols’ classrooms one at a time. After finishing the classroom, they have to go to the teacher’s office, public venues and other places to work 360 degrees without blind spots, to achieve full coverage and efficient disinfection. With the help of disinfection robots, coupled with the full cooperation of various departments of the school and strict prevention of death, it will definitely be able to effectively prevent and block the spread of the virus, and do a good job in the prevention, control and elimination of epidemics and epidemics.
The school considered the following points when purchasing this atomized disinfection robot:
1. The chassis of the autonomous automatic disinfection robot must be stable and mature: As early as 2018, BooCax combined the positioning and navigation SLAM with UWB, lidar, depth vision and control host to create the robot core solution product "Navi++", and then Launched the "Navi++Pro" positioning navigation system, which can integrate reflector positioning and natural structure positioning technology to achieve high-precision navigation, which can meet the needs of scenes such as factory AGVs.
Therefore, BooCax has already possessed technologies such as positioning and movement of robots, sensors, and automatic charging.
2. The school has two areas: the new campus and the old campus. There is a threshold at the door of the old campus. Therefore, the disinfection robot is required to have a certain obstacle crossing ability: BooCax’ s atomizing disinfection robot has an 8 degree obstacle crossing ability. Easily cross the threshold of the door, and solve this problem of the school very well.
3. The space between the desks in the classroom area and the departments under the desks are relatively difficult to disinfect. At present, the company is developing a small robot that can spray disinfection up and down, which can meet the needs of high-speed rail stations and train stations. Disinfection provides customers with expectations of alternative solutions in the later stage.
4. It is recommended that schools use hydrogen peroxide disinfectant. In the prevention and control of new coronavirus pneumonia, 8% hydrogen peroxide disinfectant is a shortage of supplies in hospitals. The most effective terminal disinfection of all isolation wards is hydrogen peroxide; when hydrogen peroxide is used for spray disinfection, the concentration is not very high. This kind of disinfection method is a new technology that has gradually emerged and has attracted more and more attention and Practical application, it is mainly used to kill pathogens in a closed environment and rebuild a clean aseptic environment. The air + environmental surface disinfection is completed at one time. It is a safe, environmentally friendly and efficient environmental purification technology, which is atomized by disinfection equipment Spraying can thoroughly disinfect and sterilize the entire space without dead ends and residues. It is a good choice for indoor disinfection and sterilization. After the disinfection is completed, it will not affect the health of the students in normal class.
Under the epidemic situation, a variety of disinfection robots are emerging on the international market in an endless stream, and their prices vary. Similar robots of large brands can cost hundreds of thousands of dollars, which is unaffordable for schools and other public funding agencies.
Most of the chemical disinfectants commonly used in the market or in schools do contain chemicals that are not suitable for inhalation, and the hydrogen peroxide disinfectant used by BooCax disinfection robots has reduced the health risk caused by human inhalation to the minimum.
The price of this disinfection robot from BooCax is very competitive, and the Beijing Winter Olympics Organizing Committee chose this robot for preventive disinfection of the Winter Olympics test arena. The effect is highly praised by the Olympic venue staff.
From a cost perspective, consider the impact of the number of man-hours required to spray and wipe things. From various perspectives, using BooCax robots is more cost-effective than many current disinfection strategies.
