Design and build a patient room sterilization robot using disinfectant vapor and ultraviolet light to assist internet of things-based medical personnel.

Corona Virus disease has the property of spreading from humans to other human beings. The transmission system is through splashes from the nose and mouth. These splashes stick to objects, and people can get infected if they touch them. One way to prevent the coronavirus is to maintain personal and environmental hygiene by using antiseptics and disinfectants. The spraying that is currently used is still using simple tools, namely using pesticide sprayers. These tools are still vulnerable for the officers to being infected with the Covid-19 Virus because officers interact directly with objects infected with the virus. A robot has a robotic arm system on its top side to access higher areas and narrow spaces. This robot used NodeMcu ESP 8266 and was equipped with Camera Web server ESP 32. Therefore, this robot could be operated using a smartphone remotely to avoid medical personnel contact directly with used objects of previous covid patients. This robot was also equipped with a wheel tank system that aimed to reach the intricate areas to pass by ordinary wheels and had ultraviolet lights to eradicate the Covid-19 virus.
