In order to gain familiarity with the subject called Robotics, firstly, it s necessary to know the concept called a robot. The International Standards Organization defines a robot as an automatically controlled reprogrammable, multipurpose manifestative machine, with or without movement, for use in industrial automation applications. Robotics is all about designing robots, maintaining them, developing new applications and conducting research. Robots are built, and repeated exactly work in dangerous environments. Are you in a way that it enables the automatic running program. Therefore, a robot is a re-programmable engine. The field of robotics involves knowledge from a variety of allied fields like electronics, mechanics, and computer sciences and hence aspirants for this field must be well aware of the technicalities associated with these fields.
