This paper discusses about IOT-based medical assistant robot for patient monitoring. Which help to create a virtual doctor robot that enables a physician to roam about a faraway place at will virtually and even communicate with individuals there as desired. In addition to exploring some earlier similar research that aided in the development of pertinent systems, the paper will describe the study's historical context. The technology uses an IOT-based physiological parameter monitoring system and a robotic vehicle with four-wheel drive for convenient navigation. Additionally, the robot has a controller box for circuits and a mounting for a camera screen.
