Virtual reality: Creates a completely immersive experience by replacing the user’s physical reality with a simulated
                  environment.
                  Augmented reality: Overlays digital information onto the real world, creating a hybrid experience that blends the
                  physical and digital worlds.
                  Mixed reality: Combines elements of both VR and AR by overlaying digital objects onto the real world and allowing
                  users to interact with them.



                    Fill in the blanks:
                    1.   Users wear a ______headset that tracks their head movements and displays a 360-degree view of
                        the virtual world, making them feel like they are actually inside the environment.
                    2.   ____________combines elements of both VR and AR by overlaying digital objects onto the real
                        world and allowing users to interact with them.



            10.1.4 Robotics
            Artificial intelligence (AI) has a significant impact on the field of robotics. Robotics involves the design, construction,
            operation, and use of robots. AI algorithms and techniques can help robots become more intelligent, adaptive, and
            capable of performing complex tasks.
            Nowadays, autonomous robots are designed to operate independently without human intervention. They are equipped
            with sensors, actuators, and decision-making algorithms that allow them to perceive their environment, plan their
            actions, and execute tasks. AI algorithms are used to enable autonomous robots to learn from their environment and
            adapt to new situations.


























            Machine learning algorithms are also used in robotics to help robots learn from experience. For example, reinforcement
            learning can be used to train a robot to reach its destination, which may have hurdles along the way, by rewarding it
            for successful actions and penalizing it for unsuccessful actions. Another area where AI is used in robotics is computer
            vision. Computer vision enables a robot to perceive and interpret visual data from its environment. AI algorithms
            can be used to help robots recognize objects, track movement, and understand their surroundings. Natural language
            processing (NLP) is another application of  AI that helps robots understand and respond to human language, making it
            easier for humans to communicate with them.
            Thus, we observe that AI has the potential to revolutionize robotics and make robots more intelligent, adaptive, and
            capable of performing complex tasks. In turn, these developments will help improve several processes in  manufacturing,
            healthcare, education, transportation, defence, entertainment, etc.
