There are mainly two types of controllers that determine the robot’s behaviour. They are:
                 •   Simple Controller:  Pre-Programmed robots use the simplest form of controller. These

                    controllers repeat the same operation over and over.  Pre-Programmed robots are
                    insensitive to their changing environment. Car manufacturing robots are such kinds of
                    robots.

                 •  Strong Sensory Controller:  Autonomous  robots are intelligent and change their
                    response  according  to  their  ever-changing  environment.  These  robots  have  robust
                    sensory tools that allow detecting changes in the background. Humanoids, astronaut
                    robots and robots used in the educational and medical fields come under this category.



                 Sensors
                 Without the data supplied by the sense  organs, the human brain cannot perform
                 intelligently in any  given situation.  Similarly,  controllers would be unable  to perform

                 if the robot’s sensors do not constantly feed the controller about their position, force,
                 temperature, etc. The sensors are the powerhouse of a robot’s feedback system and act
                 as eyes and ears. A wide range of sensors is used in a robot system to perform the tasks.
                 These include:

                 •   Cameras allow a robot to construct a visual picture of its background.
                 •   Microphones are used to detect sounds.

                 •   Thermometers in some robots are used to sense temperature.
