Vietnamese engineer builds floor cleaning robot to disinfect patient room

The robot, made by engineers of the Institute of Applied Technology, Ministry of Science and Technology, can hold 10 liters of solution and operates continuously for 2 hours. 

On the morning of April 15, a robot named NaRoVid1 was tested at the Central Tropical Hospital Facility 2, Hanoi. Robots can operate in isolated areas to assist, instead of medical staff using disinfectant to clean the floor.

Assoc.Prof. Dr. Mai Anh Tuan, Head of the research team, said that the robot is designed with a rounded appearance, compatible materials that can be cleaned according to the recommendations of the doctors, making it most convenient during use. . The process of spray disinfection, chemical particles self-disinfecting outside, inside disinfection by UV rays.

NaRoVid1 uses smart moving algorithms, uses laser sensors, ultrasonic sensors and compass to guide, map and cycle. With dimensions of 50cm x 60cm x 30cm, the robot can move into tight spaces. The ability to store up to 10 liters of solution helps to add disinfectant solution is spaced, if every 30 minutes wipe once, the robot takes about 15 minutes to operate. NaRoVid also features a circular motion set by the operator flexibly, automatically returning to the charging position after the end of the cycle.

Master, Dr. Tran Minh Quan, Deputy Head of Examination Department, Central Hospital for Tropical Diseases 2 evaluated, the application of robots helps doctors save time and minimize the risk of infection. Using the robot, a day, the medical staff only needs to replenish the solution 3 times, instead of going to the hospital room dozens of times a day if cleaning manually.

The team said it will continue to improve features, increasing accuracy when the robot operates. Also integrating many other uses such as transportation of drugs, food, medical supplies, mobile reception stations .

The Institute of Technology Application will coordinate with production units to transfer technology, make plans to produce robots in large quantities, promptly respond to hospitals and isolation areas when required.
