What are the specifications for DTMF controlled robot using aurdino?

Android-controlled robot project make use of an Android mobile phone for robotic control with the help of Bluetooth technology. It is a simple robotic projects using micro-controller. We have already seen Mobile Controlled Robot using DTMF technology that uses call-based method to control the robot. Also many wireless robots use RF modules. The control commands available are more than RF modules. Robot controlled by Smartphone is superior to all these robots.

This project is a robot controlled by Bluetooth. To do this, the Android mobile user has to install an application on their mobile. Then the user needs to turn on Bluetooth on the mobile. The wireless communication techniques used to control the robot is Bluetooth technology. The user can use various commands such as forward, rewind, stop move left, move right. These commands are sent from the Android mobile phone to the Bluetooth receiver. Robot based on Android has a Bluetooth receiving unit that receives the commands and give it to the micro-controller circuit to control the motors. The micro-controller then transmits the signal to the ICs of the motor driver to drive the motors.
