The branch of mechanical engineering, electrical engineering, and computer science that deals
                 with the design, construction, operation, and application of robots, as well as computer systems
                 for their control, sensory feedback, and information processing is called Robotics. In other words,
                 robotics is the engineering science and technology of robots, their designing, manufacturing,
                 and application.

                     USES OF ROBOTICS

                 Robots are used in various sectors, but they can be broadly classified into two types—industrial
                 robots and service robots.
                 Industrial robots are mainly used in manufacturing industries such as automotives industries.
                 These robots are programmed using computers.

                 Service robots include domestic robots that clean the carpet or cut grass in the garden and
                 move on their own.  They are  fully or  semi-autonomous robots  and  controlled  by electronic
                 circuits. Some of the service robots are simple versions with very few IC (Integrated Circuit) chips
                 while others have more than hundred ICs.

                     ANDROIDS

                 When a robot is designed to execute highly sophisticated instructions,
                 it is  referred to as an  android. An android  is  a robot  or synthetically
                 designed organism which is designed to look and act like a human. They
                 have a body which has flesh like covering. They have largely been seen
                 in science fiction movies. Efforts, research, and developments in robotics
                 have allowed the design of functional and realistic humanoid robots The
                 Sophia robot is the latest example of humanoid robot.                                  Android

                     MECHATRONICS

                 The  field  of  mechanics  and  electronics  together  have  given  rise  to  a
                 new emerging sector called mechatronics. Now, robotics is exploring
                 the possibility of helping physically challenged people overcome their
                 limitations. For example, a mechatronic arm is being developed to assist
                 people who have a problem with basic mobility.
