Venkatesh's ELECTRONICS MADE EASY: CELL PHONE OPERATED ROBOT

ABSTRACT

The main aim for design the project is, actually all countries need military force, it is necessary for protecting the country. At the time of wars so many soldiers lost their lives, and country lost the Daring and dynamic personality. So here human lost increasing day by day. We think about it from such a long time how to reduce the human loss. Then we made one equipment to reduce human loss.

Now-a-days Tracing and attacking enemies (or) militants at different areas are very much difficult for the soldiers. We have implemented a solution for the problem by replacing soldier with a Robot Soldiers completely controlled by GSM/CDMA network. This is constructed with two motors. Here two are linear motors . One is for forward and backward rotations (directions), another one is for rotating left and right directions.. The entire Robot is constructed with popular Micro-Controller Series MCS51 series 8051 compatible 89S52 Micro-Controller DTMF network, (GSM Modem) & etc.

Initially we will have to dial up through any GSM network (or) CDMA (or) from any other remote places at least by land line. After completion of the pre-defined rings it enters into the auto answering mode and transmits the picture from the destination area to the controller room that can be watched in any display devices. So according to the picture the person who is there in the control room can take necessary operations

In this project, we present controlling of a robot using DTMF technique. The robot is controlled by a mobile phone that makes call to the other mobile phone attached to the robot. In the course of the call, if any button is pressed, tone corresponding to the button pressed is heard at the other end of the call. This tone is called dual tone multi frequency (DTMF). Using DTMF code, direction of motion of the robot can be controlled by mobile phone.
