ABSTRACT
The objective of this project is to control the robot for security application. The spy robot with wireless camera is very useful in the secured places such as home, banks super market etc. We can also use this robot for industrial security application.
This project is designed with Microcontroller, wireless Camera, keypad, Robot model, Encoder, Decoder, RF Transmitter and Receiver and Driver Circuits along with Motors.
In this project Camera is placed on the robot to capture the pictures in the moving path.
Microcontroller is used to drive the Robot. Here the microcontroller is the flash type reprogrammable micro controller in which we have already programmed with our objective. In this project RF section is used to transfer the control information data between microcontroller and control side. RF transmitter section is connected in the control side and RF Receiver section is connected in the microcontroller side.
WORKING PRINCIPLE
A wireless camera is placed on the robot to capture the pictures in the moving path. The captured picture is displayed in the television as per the displayed picture the corresponding control information signal from the control side is encoded with the help of encoder and transmitted to microcontroller through RF Transmitter. The RF Receiver receives the signal in which carrier signals are removed then the signal is given to decoder. Here the encoded signal is decoded to original signal as per transmitted from the control side. Then the decoded signal is fed to Microcontroller.
Microcontroller receives that signals and activates the Driver Circuit. Driver Circuit consists of Transistor which acts as switch to turn ON and turn OFF the relay. The relay output is given to motors which are attached in the robot. If you want to drive the robot in the forward direction corresponding control information is transmitted from control side to Receiver section. In Receiver section the microcontroller controls the robot in forward direction. Then the captured picture is transmitted to television.
