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.

Programming

Using the Board with AVR Studio and Flashing with XploreFlash

Step 1: Xplore flash is based on various opensource software, it requires avrdude. Avrdude is part of WinAVR GCC complier. Download and install it.

Step 2:To connect Development board with computer USB driver is required. Windows USB to UART Drivers for CP2102

For Other Operating system please download from Silicon Labs website.

Step 3: Download and install XploreFlash GUI. (XploreFlash GUI is based on AVRDUDESS)

Step 4: Follow the steps on images below to flash the board.

Note: The GUI software will require .NET framework 2.0 or later please download and install it.

Using the Board with Arduino Software
