To break the chain of transmission of the coronavirus / COVID -19, many professionals and experts from various fields are trying to make innovations that can reduce or even eliminate this case of COVID-19. One of them was done by Telkom University Bandung students in creating an Autonomous UVC Mobile Robot or abbreviated as AUMR armed with type C or UVC ultraviolet rays that are expected to kill viruses, including the virus that causes COVID 19 disease in the Bandung Techno Park Laboratory Telkom University, Bandung Regency, Thursday (5/14).

UVC rays emanating from six lamps mounted on the robot body are believed to have the function to disinfect and sterilize in isolation rooms for positive patients with Covid-19 without direct human intervention. During the sterilization process, there should be no humans around the robot. Because humans who are exposed to UVC rays will experience damage to the skin and eyes. However, cloth curtains can be used as a safe protector, if sterilization is forced to do in a room with humans.

Rector of Telkom University, Prof. Dr. Adiwijaya stated that the Autonomous UVC Mobile Robot (Ultraviolet Type C) was the first AUMR robot used in Indonesia. Previous similar tools have been used in several countries, one of which is Denmark.

This robot can be operated for a period of five hours after it was first turned on. In addition to the UVC work system can take about one hour. For the control function of this robot, it can be done in several modes. Like using a remote control, and autonomous control mode by doing line tracking or laser range navigation.

“This robot has also been equipped with ultrasonic sensors to avoid crashing into nearby objects,” said Adiwijaya.

Based on Adiwijaya’s information, the AUMR robot works with UV light in the range of 200 nm and 280 nm, which can absorb biological organisms such as DNA, RNA, and protein. This absorption will cause the breakdown of protein cell walls and of course the death of the organism.

The absorption of UVC rays by DNA and RNA, in particular, the thymine base is known to cause inactivation of the double-stranded DNA or RNA through the formation of thymine dimers. If this dimer is sufficiently produced in DNA, the DNA replication process will be disrupted and of course, the cell cannot replicate.

Adiwijaya in his official statement also explained, the increasing number of the suspect and positive cases of COVID in Indonesia, various actions taken by the medical team, one of which was to isolate suspect or positive patients of COVID-19.

According to him, the process of disinfection and sterilization in the isolation room also needs to be considered to reduce the activity of contamination in very small microorganisms such as Corona Virus or Covid-19, both attached to inanimate objects, floors, or air around the isolation room.

He added that if the direct interaction between the medical team and corona positive patients opened up the opportunity for Covid-19 to spread very quickly to the medical team from the hospital. So as to reduce the risk of transmission in the Hospital area (especially near isolation rooms), sterilization methods and equipment used are used remotely.

According to Adiwijaya, this robot has also been equipped with ultrasonic sensors so as not to crash into nearby objects, including in the Corona Covid-19 isolation room. For research and development costs, the AUMR robot needs a budget of around Rp. 250 million.

“When compared to the AUMR robot from outside which costs $ 80,000- $ 90,000, the AUMR robot is still so affordable,” Adiwijaya said.
