Android Controlled Robot using 8051 Microcontroller
Author	Gaurav Khadasane
Description	Android controlled robot using 8051 and bluetooth Image: http://www.8051projects.net/images/android-controlled-robot.jpg Our robot expert Gaurav Khadasane has come up with another innovative way to control a robot. He is controlling his robot from an android phone (with a Android GUI application) over bluetooth. Project uses our favourite 8051 microcontroller and HC-05 bluetooth module. In this project 8051 and bluetooth module are communicating over uart @9600bps. Bluetooth module HC-05 is controlled via simple AT commands. This module comes in SMD package and works on 3.3v power supply. The BT module is a SPP supported profile so it can be connected easily to any controller or embedded device. In this profile the data sent and receive to module directly comes on the RX pin of microcontroller. It becomes really easy to make your device bluetooth compatible. L293D H-Bridge motor driver are used to control two DC motors. A readymade compact size chassis is used to avoid the chassis assembly comlexities :) 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. Finally the Android application, You can get Bluecontrol app from Google Play Click image below to go to Google Play Image: https://lh5.ggpht.com/zMLqXFWOLnnbZXcGZ-V29SR1N8RqaDsv4PVLPPeMqM-9yL4UKGqF1aSaltnA1Ml-d6I=w124 Here is a working video of the project If you have any doubts or comments Please use forum...

I want assembly c code for the above project... ..can u pls mail me.!!!!

this is very interesting and helpful really.which compiler i should use for the c code mikroC or keiluvision or suggest the link for me.

@musah, Compiler is keil uVision.

Onluly codes present in inttoduction PDF file is to be burned to uc for working of project

you need to assemble the BT.ASM code first and generate a hex file. then flash it to controller. BT.hex is already provided if you do not want to assemble it.

i'm using hc-06 bluetooth module but not able to get any data from it at micro controller. Is any way to check whether Bluetooth is transmitting data or not"?

@pady005 connect module to PC via max232 and see if you get any data there. Post in forum for more help.

Can you provide step wise tutorial on how to make it ? pls

Can you please help send me the circuit diagram of this project..!!

@catty, Please download it using green color download button :)

what is CONN-SIL6 in the circuit diagram? im sorry for this im just a student. thank you! :)

CONN-SIL6 is a connector or header. A burgstrip type through hole component gets soldered into it.

Can i get the source code of this project please n thank u for ur kindness..

guys plz plz help me out its very urgent .....
