Robotics is the branch of science that involves study around developing machines, a.k.a. robots that could carry out certain tasks, which are usually either performed by human being or are even beyond human capability. Historical roots of robots are as ancient as the Greek mythology. There are references of androids in Greek mythology, which are nothing but mythical forms of what we call robots today.
Beginning from the first half of 20th centuries, some serious developments in the field of artificial intelligence (A.I.) and robotics have been done by the scientists of various countries. Ever since it has been a constant endeavor of robotics scientists to build robots that can automatically take care of a variety of complex tasks without requiring manual intervention. Today, the advancements in the technology have given rise to the kind of robots that are very precise in their work and quick in performing repetitive tasks without any fatigue.
Developments in engineering and technology have taken shape in form of certain robots that are quite useful in the human applications, such as medical, surgery, mining, computation, researches, applied sciences, construction, mechanics, and even weaponry. These robots are capable of bearing any level of stress, temperatures, without demanding anything except the regular maintenance and electrical power. Considering the benefits of robotics and its anticipated future applications, robotics has become an important part of technical education in most of the world-class universities.
At the same time, a number of studies and researches are being performed at a steady rate by numerous scientists in several countries to develop machines that have capability to make independent decisions based on the instructions given to them. Undoubtedly, it will be a great victory of humankind to develop such robots that can complete the entire tasks with utmost efficiency using their own intelligence without requiring any human instructions.
