Android is very popular OS these days. It is capturing interests of millions of application developers. In this project we used an Android application to control a robot. Further details of the project are given below:
A Bluetooth module (HC-05) is communicating with 8051 module at the rate of 9.6 kbps. HC-05 can operate just on 3.3v, available in SMD package and can be connected easily with any controller or embedded device. The data can be received at micro-controller pin without any difficulty.
L293D H-Bridge motor driver are used to control two DC motors. A ready made compact size chassis is used to avoid the chassis assembly complexities. The chassis contains 2 decks the lower is used for BO motors fitting the upper is used as a battery stack. On top plate the controller board is mounted by screw fitting.
