  2. Service Robots

    • Assist humans in various tasks
    • Examples: vacuum cleaners, lawnmowers

  3. Autonomous Vehicles

    • Self-driving cars and drones
    • Examples: Tesla Autopilot, DJI Phantom

  4. Humanoid Robots

    • Designed to resemble humans
    • Examples: Honda ASIMO, Boston Dynamics Atlas

  5. Social Robots

    • Interact with humans socially
    • Examples: Pepper, Jibo

Key Components of Robotics Systems​
