Electronics

Robo Controller Board


  • The Robo Board: This is the heart of the robot. The board has following ICs
    • Motor Driver: A L293D Motor driver on board is used to control the two driving motors of the Robot
    • DTMF Decoder: A MT8870 or compatible IC is used to convert DTMF mobile tones to digits, which helps in making Mobile controlled Robot
    • Microcontroller: The board feature a Atmega8 (Atmega328 can also be used) controller. Figure below shows the way in which various units are connected to the microcontroller.

Sensor Sheild

The sensor sheild has a comparator IC that gives logical high when any of the right, Middle or left sensors are detected.The sensor sheild has following sensors:

  • 3 IR pairs for line following
  • 3 IR Pairs for obstacle avoidance
  • 3 Light Dependent Resistors

Notice the DIP switch shown in the image below, it used to select the above three sensor options.
