PROJECT TYPE
Micro controller (8051) based hardware design with
Software development.
PROJECT DESCRIPTION
Do you want to monitor various things at some remote place where a human being cannot go? Do you think that is it possible? Yes, it is possible by making use of a mobile robot. How wonder if it is a wireless! The current design of the ‘RF based spying robot’ is an application of that which does the above mentioned things for you. The design is based on 8051 micro controller and various interfaces like RF TX and Rx,dc motors etc.
The whole system consists is divided into two modules, the TX module and the Rx module. The TX module contains keyboard(switch) operation used to control the motion of the robot and the Rx module contains the actual machine(robot) .The robot moves in various directions as per the switching action at the transmitting side. The different key press generates different RF signals. The Rx receives these signals and moves accordingly. But the important thing to be noted here is that there is no connection between the TX and Rx section. Radio frequency (RF signal) makes this task very simple. The RF TX sends a signal to the micro controller at the Rx side as soon as any key is pressed at the TX side.
Now the micro controller at the Rx side rotates dc motors to make the robot move in various directions. Here a mechanical arrangement is provided for the actual apperance of the robot. The main highlight of this design is data transmission without any wire(wireless data transfer) using RF communication. The project design is also provided with an important feature of viewing the images of robotic movement in its path at the remote side on a PC for a total of 360 deg rotation. For this a wireless camera is arranged with a dc motor on to the robot. Thus the design is said to be a Spying Robot with wireless camera.
The main highlight of this design is data transmission without any wire and hence it is known as RF based Mobile Robot. The radio frequency that is being used here is 433MHz.
