Introduction
In this tutorial we will see about building a simple dtmf controlled robot. Whenever we make a call, and press keys, dtmf tones are generated and transmitted. The tones can be easily decoded using a IC like MT8870. This enables a lot of possibilities for wireless control over mobile and telephone.
Assembling the Robot Cart
For this we will be using Xplore Robot Chasis as shown. The basic components would be
Assembled Robot chasis with wheels and motors
- Xplore Robo Chasis
- Xplore AVR Robo development board with Integrated DTMF
- Battery Operated [BO] Motors for driving wheels
- Castor as a free wheel.
You could make your own hardware setup as per the schematics discussed in the tutorial. The setup is shown in the pictures below.
