  • Introduction to Wireless Communication in Robotics

    As robots become more advanced, the ability to communicate without wires becomes essential. Wireless communication allows robots to be controlled remotely, share data, and even work together in teams. In this section, we’ll explore what wireless communication is and how it helps us build smarter and more interactive robots.

    • 🤖 What is Wireless Communication?

      • Wireless communication is the transfer of data between two or more devices without physical connection using radio waves, infrared, or Bluetooth.
      • It allows us to send commands from a remote control, smartphone, or another device to the robot.

      📡 Why Do Robots Need Wireless Communication?

      • To be controlled remotely from a phone, tablet, or computer
      • To operate in places where direct contact is not possible (e.g., search & rescue, drones)
      • To work in groups or swarms, sharing data wirelessly

       

    • 🔌 Types of Wireless Communication in Robotics

      Technology Range Common Uses
      Bluetooth 10–30 meters Mobile app control, short-range data transfer
      Wi-Fi Up to 100 meters Internet-connected robots, home automation
      Infrared (IR) Line of sight, short range Remote controls, TV robots
      RF Modules Up to 500 meters (varies) Long-range remote control, wireless sensors

      📘 What We’ll Focus On

      In this course, we’ll primarily work with Bluetooth communication using modules like HC-05 or HC-06. These are beginner-friendly, affordable, and perfect for controlling your robot using a phone app.

       

      By the end of this section, you should be able to:

      • Understand the need for wireless communication in robotics
      • Identify different wireless technologies and their uses
      • Prepare to use Bluetooth in your own robot projects
