ROBOTICS

                                                           ROBOTICS

• The word 'robotics' has been derived from the word robot. It was introduced to the public by the Czech writer Karel Capek. This word comes from the Slavic word 'robota', which means slave or servant.     
• A machine that is programmed by a computer and reduces human efforts that machine is known as robot.
• Robotics is a branch of engineering and science. It deals with the design, construction, operation, and use of robots, including the design of computer systems of their control sensory feedback, and information processing. 

EXAMPLE: 

Sophia is a social humanoid robot created by Hanson Robotics; a company based in Hong Kong. She was activated on February 14, 2016, and made her first public appearance in mid-March of the same year. Sophia is designed as a "social robot" capable of mimicking human social behavior and eliciting feelings of love in people.

        FIRST ROBOT INVENTED:

• George Devol designed the first industrial robot, Unimate. He originally termed it "universal Automation" before shortening it to "Unimation," which became the name of the pioneering robot company established in 1962.

ADVANTAGES OF ROBOTICS:

• Increased efficiency and productivity: Robots can complete tasks faster and more consistently than humans.
• Improved accuracy: Robots can perform tasks with a level of precision and accuracy that is hard to match by humans.
• Improved safety: Robots are capable of operating in dangerous environments, thereby minimizing the risk of human injury.

• Consistency in Quality Output: Robots can consistently produce high-quality output without the variations that may occur in human-controlled processes.

DISADVANTAGES OF ROBOTICS:

• Impact on social interaction: The increasing use of robots in customer service roles may reduce human-to-human interactions, potentially affecting social skills and relationships.

• Cost Effectiveness: Maintenance and security of robots can be expensive.

• Challenges of Job Displacement: The increase in automation could lead to job displacement as robots take on roles traditionally held by humans.

•  Power and Programming: Robots are driven by power and thus require substantial amounts of electricity, which can lead to them being considered not eco-friendly.

  

                  

           

VIRTUAL REALITY

                               VIRTUAL REALITY 

• The term "virtual" has been used in the computer sense of "not physically existing but made to appear by software.
• 
  Images created by a computer that seem to envelop the viewer and appear nearly real are referred to as virtual reality. VR experiences are now in the mainstream of entertainment, healthcare, military, business, and more, and are emerging as a positive force in the world in various ways.

    TYPES OF VIRTUAL REALITY:

•  Non-Immersive: In a non-immersive virtual reality, users can control characters or activities in a 3D world using a computer screen with keyboards, joysticks or controllers, but the environment itself is not directly interacting with the user. Non-immersive experiences, allow a user to exist within a digital space without displacing them from their physical surroundings.
• Semi-Immersive: Semi-immersive virtual reality systems place a user in a 3D environment without incorporating any physical movement. Heavily focusing on the visual element, this type of simulation uses a computer screen and, in some cases, a headset to blend both non-immersive and fully immersive elements. 
• Fully Immersive: Fully immersive virtual reality systems place users in a computer-generated environment that is perceived as real. Equipped with powerful computers, head-mounted displays and indicators fitted with sensors, users can interact with the environment as it occurs around them. This type of virtual reality incorporates as many senses as possible, and therefore, requires the most thorough process of data collection in comparison to other systems. 

 

HOW VIRTUAL REALITY HELPS IN TODAYS DIGITAL WORLD: 

• 
  It is vital for enhancing education, training, and experiences.
• It creates immersive, interactive environments that improve learning,
  simulate real-world scenarios, and enhance empathy, ultimately advancing fields like education, healthcare, and entertainment.
• It can help people learn new skills and face their fears in a safe environment.
• It is used by therapists for the treatment of phobias, but today, some therapists also use it for a range of conditions.

DISADVANTAGES OF VIRTUAL REALITY:

• High cost of equipment and technology.
• Lack of genuine communication and social interaction.
• Lack of adaptability and flexibility in virtual environment.
• 
  Potential for addiction and obsession with the virtual world.
  
• Health concerns such as anxiety, eye strain, dizziness, and radiation exposure. 

Utilizing virtual reality can be beneficial, but it should be done within certain limits.

      CYBER SECURITY!

• Cybersecurity is not just about protecting our devices; it's about safeguarding our personal information, finances, and privacy from malicious actors. By adopting smart online habits and being vigilant, we can significantly reduce the chances of falling victim to online scams and fraud.  

• In today's digital age, much of our work is conducted online, making it crucial to understand how to maintain safety online. Understanding how to navigate the online world securely and avoid fraud is crucial in today's digital age.

• CYBERSECURITY IS ESSENTIAL BECAUSE IT HELPS TO:
  
  
  

i) Protect organizations and individuals from cyber-attacks.

ii) Prevents data breaches, identity theft, and other types of cybercrime.

iii) Safeguard sensitive personal and financial information intellectual property, and critical infrastructure.

iv) Defend against malware, viruses and social engineering.

v) Protect sensitive customer data in banking data, and in many other works.

• HERE ARE SOME ESSENTIAL TIPS TO STAY SAFE ONLINE:
  

1. Limit Personal Information: Be mindful of the personal details you share on the internet. The less information available, the less there is for cybercriminals to exploit.

2. Privacy Settings: Always turn on privacy settings on social media and other platforms to control who can see your information.

3. Smart Browsing: Navigate the web wisely by avoiding suspicious websites and links that could lead to phishing sites or malware.

4. Careful Download: Only download files and applications from trusted sources to prevent introducing malware to your devices.

5. Secure Connections: Ensure your internet connection is secure, especially when conducting financial transactions or sharing sensitive information.

6. Strong Passwords: Use complex and unique passwords for different accounts to prevent unauthorized access.

7. Secure Shopping: When shopping online, use reputable websites with secure payment methods.

8. Think Before Posting: Consider the potential implications of what you post online, as it could be used against you.

9. Safe Socializing: Interact safely on social media by being selective about friend requests and messages from strangers.

10. Regular Updates: Keep your antivirus and malware protection software up to date to defend against the latest threats.
