    ROBOTS

                      Robots come in many shapes and sizes to carry out tasks in almost all sectors of life. Let
                      us now discuss the types of robots which are divided into five categories.

                                CLASSIFICATION OF ROBOTS

                      Robots are mainly classified into five categories. Let's learn about them.

                      PRE-PROGRAMMED ROBOTS
                      Pre-programmed robots are designed to work in a controlled environment. They are
                      used in:
                      1.  repetitive tasks that are considered boring because of their repetitive nature or too
                        dangerous to be done by humans.

                      2.  situations where the task requires a high level of accuracy.

                      3. large-scale industries and also in the field of medicine.

                      Examples of pre-programmed robots are:

                                                   Mechanical arms are used for welding doors or fixing engine
                                                   parts.

                      CyberKnife radio surgery machine is designed to operate on

                      tumors in cancer patients.

                      AUTONOMOUS ROBOTS
                      Autonomous robots are designed to work independently without human intervention.
                      They carry out tasks in an open environment and use sensors to adapt to their
                      surroundings. They can perform in the changing environment and do not require direct
                      human supervision.

                      Examples of autonomous robots are:

                                                    Roomba vacuum cleaner roams throughout the house without

                                                    human supervision.
