What do you think the cause are for the robotic revolution? In the recent several decades, robotic technology has developed to a fairly high level and has formed a revolution all around the world. I think the prerequisite of the revolution is the development of science and technology. Based on the advanced science and technology, the robotic technology can take in skills and fruits of other subjects to enhance itself. Besides, the robotic revolution is also a result of the “laziness” of human beings. Modern people live under great pressure and have endless things to do. Thus, human beings create a variety of robots to do those things can be done by machine, loosing people from some kinds of manual work. Last but not least, In some fields of science, such as astronomy, nuclear experiments and submarine explorations, researches can be very dangerous and risky or even impossible to be finished by human beings. Because of this, the use of robots becomes critical and indispensible. Nowadays, many a benefit has been brought by the profound robotic revolution to human beings in many areas such as scientific researches, manufacturing and so forth. This promising industry will certainly bring us more surprises.
