Dtmf controlled robot using AVR Revision as of 16:06, 5 February 2014 by Sandeep (Talk | contribs) (diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)

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.

The Components

For this we will be using Xplore Robot Chasis as shown. The basic components would be

• Xplore Robo Chasis
• Xplore AVR Robo development board with Integrated DTMF
• Battery Operated [BO] Motors for driving wheels
• Castor as a free wheel.

The setup is shown in the pictures below.
