More and more different types of robots are used to combat the coronavirus (COVID19), they are gradually replacing humans at the forefront in the fight against the pandemic, the Robotec company did not stand aside and developed several models of robots capable of autonomously, without human intervention, disinfecting premises, neutralizing bacteria, fungi and most importantly - viruses. 

Santec Smart Disinfection Robot destroys 99.99% of pathogens in autonomous mode using ultraviolet and dry steam disinfector. Santec operates unattended 24 × 7 to keep your workplace, business or educational facility safe without the use of chemicals or manual labor. 

Santec uses high power germicidal ultraviolet light at 253.7 nm to destroy the DNA and RNA structures of bacteria and viruses without the use of chemicals and in an environmentally friendly manner. The radiation power of the UV lamp meets the requirements of GB19258 and the “Technical Specification for Disinfection”, and the radiation intensity of each lamp is about 300 µW / cm² (measured at a distance of 1 m).

For disinfection in models (Santec A, E, S), dry steam is also used - dry fog particles less than 10 microns in size, such a fog penetrates into any niches and cavities. The spray effect meets the "Disinfection Specification" and the airborne bacteria kill rate reaches 99.999%. 

Ultrasonic spraying of a liquid disinfectant has a number of advantages over atomizers based on nozzles: 

- 10 times smaller droplet diameter (the diameter of the ultrasonic fog generator droplets is up to 10 microns, and the nozzles form 50-200 microns); 

- low consumption of a disinfectant solution for a large disinfected volume; 

- a small amount of disinfectant is needed - it does not settle for a long time, it effectively penetrates into all hidden surfaces; 

- there is no settling of large droplets of disinfectant solution on the surface of furniture, objects and people. 

Using the properties of "dry fog" allows disinfection of not only surfaces, but also the volume of air - all particles with viruses and bacteria in the air will meet the smallest drops of aerosol - disinfectant on their way and will be neutralized. This is called volumetric air disinfection. 

The air disinfector forms an ultra-fine-droplet water mist - the droplet diameter is 1-5 microns, in contrast to the nozzles, which irrigate surfaces with large droplets more (surface disinfection). The concentration of solutions, the method of application, the amount and time of spraying are determined by the manufacturer of disinfectants - recommendations for use. 

Robotec robots incorporate the industry-leading latest positioning and navigation technology to ensure long-term stable performance in challenging environments with large numbers of robots, living and non-living objects. The navigation system is based on VSLAM technology, but we use a combination of sensors such as: LIDAR, US, IR sensors, inertial sensors, wheel odometers. 

Equipped with multisensors and intelligent algorithms, the robot automatically turns off the UV lamps if it detects a person or animal nearby. 

Using a combination of UV and dry disinfecting steam allows you to achieve the maximum disinfection effect that is unattainable with conventional methods using sprayers and local UV irradiation. 

In addition, the Santec S Smart Robot recognizes the places most frequently used by a person, places and objects that a person touches most often, and provides additional intensive disinfection of these places in automatic mode.

Robots have simple and understandable modes of operation:
- automatic execution of disinfection without human intervention with a default duration;
- user-defined mode - automatically performs disinfection without human intervention along a predetermined route with a user-defined duration;
- static mode - a remote controlled robot reaches a certain place and performs disinfection. Remote control and tracking of robot operations is carried out using a computer, smartphone or tablet.
