ABSTRACT
We cannot forget 9/11 when 101 people including nine foreigners and 14 policemen have lost their lives while about 300 people were injured in the worst terror attack seen in the country in which desperate men fired indiscriminately at people. Being an ex– defense person, my blood was boiling as our brave soldiers were fighting the militants to free all the hostages from Mumbai hotels. It struck an idea in my mind, why can’t we make a robot to tackle such type of situation.
INTRODUCTION
1.1 LITERATURE SURVEY:-
RF Controlled spy robot is an exclusive project where the direction of the movement of Robot can be changed using wireless technologies. The Robot will be placed different from that of from where it is controlled. This project can also be carried out using wiring processes. But the main disadvantage when we go for wiring is that, data transmission and reception may not be perfect and the data may be lost if the wiring is not done properly. Thus, the Robot movement is controlled using wireless concept in this project. In this project, the controlling of the Robot is done from the transmitter and this information will be passed to the Robot in a wireless fashion.
STUDY AND ANALYSIS:-
The project aims at making the robot to move in a particular direction, connected at the receiver side, specified by the user at the transmitter side using RF technology. The project uses the RF technology, wireless camera and Embedded Systems to design this application. The main objective of this project is to design a system that continuously checks for the data received from the transmitter section and also monitor video captured by the and transmit the same to remotely placed TV or a PC and we can even attack by firing the gun attached to this robot if the target is confirmed.
ORGANIZATION OF THE PROJECT:-
In view of the proposed thesis work explanation of theoretical aspects and algorithms used in this work are presented as per the sequence described below.
Chapter 1 describes a brief review of the objectives and goals of the work.
Chapter 2 discusses the existing technologies and the study of various technologies in detail.
Chapter 3 describes the Block diagram, Circuit diagram of the project and its description. The construction and description of various modules used for the application are described in detail.
Chapter 4 explains the Software tools required for the project, the Code developed for the design.
Chapter 5 presents the results, overall conclusions of the study and proposes possible improvements and directions of future research work.
Rectifier:
The output from the transformer is fed to the rectifier. It converts A.C. into pulsating D.C. The rectifier may be a half wave or a full wave rectifier. In this project, a bridge rectifier is used because of its merits like good stability and full wave rectification.
Filter:
Capacitive filter is used in this project. It removes the ripples from the output of rectifier and smoothens the D.C. Output received from this filter is constant until the mains voltage and load is maintained constant. However, if either of the two is varied, D.C. voltage received at this point changes. Therefore a regulator is applied at the output stage.
Voltage regulator:
As the name itself implies, it regulates the input applied to it. A voltage regulator is an electrical regulator designed to automatically maintain a constant voltage level. In this project, power supply of 5V and 12V are required. In order to obtain these voltage levels, 7805 and 7812 voltage regulators are to be used. The first number 78 represents positive supply and the numbers 05, 12 represent the required output voltage levels.
3.3 Microcontrollers:
Microprocessors and microcontrollers are widely used in embedded systems products. Microcontroller is a programmable device. A microcontroller has a CPU in addition to a fixed amount of RAM, ROM, I/O ports and a timer embedded all on a single chip. The fixed amount of on-chip ROM, RAM and number of I/O ports in microcontrollers makes them ideal for many applications in which cost and space are critical.
Conclusion
The implementation of RF based spy robot is done successfully. The communication is properly done without any interference between different modules in the design. Design is done to meet all the specifications and requirements. Software tools like Keil Uvision Simulator, Proload to dump the source code into the microcontroller, Orcad Lite for the schematic diagram have been used to develop the software code before realizing the hardware.
