In our daily life we use robots everywhere and it has become the part of our life and the most important invention is mobile phone. People become mad and hopeless when their phone stops working. We believe on our smartphones and computers than people and that is the reason we store important documents in it instead of telling it to our family, because we know that human can betray but computers will not. We are totally depended on robots like we use A.C., Television, refrigerator, etc. The common definition of robot says that a robot is a machine which is programmable by a computer and can carry out complex series of task automatically. Previously people used to walk miles after miles to reach a destination but now we can go to various place by car, ship, airplane, train, etc. We can connect to various places just by a single call and everything is done by a single robot. The most invention which revolutionized the world is the introduction of artificial intelligence introduced by John McCarthy along with Alan Turing. It made a challenging situation in humans because it has the capability to work life human by using sensors and programming. Now a days, most of the people know various kind of programming languages JAVA, PYTHON, RUBY, C++, etc. These programming languages help to interact humans with computer and developing various kind of features and technologies by typing codes. The basic moto of a software company is to uplift space and time and that is what we are working everyday for. Previously people used to make houses but now we make buildings because of huge capacity which relates to space management and the use less time which means time management. That is the basic moto of using robots. Previously, without robots, a car used to take 1 month to be built but now due to the usage of robots and assembly system, a company produces one car in one minute. Usage of robots saves time which is especially important. Now scientists are moving towards the invention of humanoid robots and it has pros and cons. The advantage is that the work of people will become easier and the people may use it as a companion those who live alone. It will also save life of soldiers by using robots instead of humans in war. It will also do various task which might be dangerous for humans. Robots have many advantages, but it has only a single disadvantage and this disadvantage can make the advantages of robots worthless which is “LOSS OF JOBS”. About 66% of the world population, will become jobless due to the usage of robots, but a most important question I would ask, when the first computer was introduced in 1956 in India and his name was “hec-2c”. At that time, there were many strikes regarding this issue because the usage of computers would make the workers jobless but was anyone unable to stop the usage of computer. The very people who strike the computer are now using it with joy and the computer has become the need of global technology. It is true that many people lost the job due this reason but it also helped the world for revolution, and the introduction of robots will reduce the expense of many things because robots do not require food and other luxury thing and many poor people will live the life with joy. You can't stop revolution to occur because it is the law of life. Revolution is unstoppable and undeniable, and everybody has to follow the theory of SURVIVAL OF THE FITTEST by Charles Darwin. Every aspect of life has its pros and cons and we must accept it because it is the truth of life.
