Drowning man catches at a straw, a common proverb that still in effect for the practical scenario. When anybody drowns, it is definitely an emergency. A human being without only 4 minutes of oxygen dies pathetically. So helping a drowning person is a time-restricted crisis. When a human rescuer takes much time then a rescuer robot then surely the robot surely becomes very important. Actually, this happened to the RTS developers when they tried to test their recently developed rescuer copter robot called PARS.
Pars is a copter robot has a capacity to fly at an operating speed of about 22 miles per hour with a working range of 2.8 miles circularly. It has the ability to carry life support for three persons. During the test trial, this flying robot defeated its human counterpart by reaching the spot 69 seconds ahead. It took only 22 seconds to reach there and release the lifesaver package while on the other hand the human rescuer took 91 seconds to reach the spot by manual swimming.
The PARS rescuer drone was tested for several parameters. The developing team tested for its stability while it flies, its accuracy to drop the life saving payloads, and the team also tested its ability to perform in both daylight and nighttime. The most convincing part on testing its feasibility to operate in nighttime was the illumination properties of the bot. Because it is designed with LED lamps on its body, this bot was clearly visible in the sky, implying that it can send a positive signal to the endangered person that help is on the way.
