RF Controlled SPY ROBOT
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.
Out new Combat robot is pc operated , it has got two barrel turret through bullet can be fired, pc camera in synchronization with the turret can rotate up and down ,left and right up to a safe firing limit. turret and camera mechanism has been installed on my spy robot vehicle, which has all the function like tank, Turing to any angle on its axis, moving forward and reverse turning left and right, running instantly into reverse direction.
This robot is radio operated self powered, and has all the controls like a normal car. A pair of laser gun has been installed on it, so that it can fire on enemy remotely when required this is not possible until a wireless camera is installed. Wireless camera will send real time video and audio signals which could be seen on a remote monitor and action can be taken accordingly. It can silently enter into enemy area and send us all the information through its’ tiny camera eyes. It is designed for, fighting as well as suicide attack.

Introduction
RF Controlled spy robt 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.
There are several wireless technologies to accomplish this task. The protocol used in this project is RF Technology.
To control the direction of the Robot, predefined keys has to given as commands from the transmitter section. The data from the transmitter section is transmitted and will be received by microcontroller at the receiver section. The data, while before being transmitted, will be converted into a format suitable for transmission. i.e., data will be encoded.
At the receiving end, the receiver section receives this data. The data received will be decoded being before given to the microcontroller for further processing. Now, it is the job of the controller to read the data and perform the corresponding action i.e., move the Robot in that particular direction based on the command received from the transmitter end. The microcontroller at the receiver end continuously receives the video signal from a wireless camera which is attached to the robo and this robot is used to capture the video of the criminal and observe their position remotely in a TV or a PC and we can even attack by firing the gun attached to this robot if the target is confirmed.
1.1 Objective of the project
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.
This project is a device that collects data from the transmitting section, codes the data into a format that can be understood by the controlling section. This receiving section controls the direction of the robot as per the command received from the transmitter section.
The objective of the project is to develop a microcontroller based control system. It consists of a switch control module, wireless camera, RF transmitter and receiver section, microcontroller and the robotic arrangement.
1.2 Background of the Project
The software application and the hardware implementation help the microcontroller read the data received from the transmitter section and accordingly change the direction of the robot. The performance of the design is maintained by controlling unit.

Overview of the technologies used
Embedded Systems:
An embedded system can be defined as a computing device that does a specific focused job. Appliances such as the air-conditioner, VCD player, DVD player, printer, fax machine, mobile phone etc. are examples of embedded systems. Each of these appliances will have a processor and special hardware to meet the specific requirement of the application along with the embedded software that is executed by the processor for meeting that specific requirement.
The embedded software is also called “firm ware”. The desktop/laptop computer is a general purpose computer. You can use it for a variety of applications such as playing games, word processing, accounting, software development and so on.
In contrast, the software in the embedded systems is always fixed listed below:
• Embedded systems do a very specific task, they cannot be programmed to do different things. Embedded systems have very limited resources, particularly the memory. Generally, they do not have secondary storage devices such as the CDROM or the floppy disk. Embedded systems have to work against some deadlines. A specific job has to be completed within a specific time. In some embedded systems, called real-time systems, the deadlines are stringent. Missing a deadline may cause a catastrophe-loss of life or damage to property. Embedded systems are constrained for power. As many embedded systems operate through a battery, the power consumption has to be very low.
• Some embedded systems have to operate in extreme environmental conditions such as very high temperatures and humidity.
Following are the advantages of Embedded Systems:
1. They are designed to do a specific task and have real time performance constraints which must be met.
2. They allow the system hardware to be simplified so costs are reduced.
3. They are usually in the form of small computerized parts in larger devices which serve a general purpose.
The program instructions for embedded systems run with limited computer hardware resources, little memory and small or even non-existent keyboard or screen.
RF Technology:
RF refers to radio frequency, the mode of communication for wireless technologies of all kinds, including cordless phones, radar, ham radio, GPS and radio and television broadcasts. RF technology is so much a part of our lives we scarcely notice it for its ubiquity. From baby monitors to cell phones, Bluetooth to remote control toys, RF waves are all around us. RF waves are electromagnetic waves which propagate at the speed of light, or 186,000 miles per second (300,000 km/s). The frequencies of RF waves, however, are slower than those of visible light, making RF waves invisible to the human eye.
The frequency of a wave is determined by its oscillations or cycles per second. One cycle is one hertz (Hz), 1,000 cycles is 1 kilohertz (KHz). A station on the AM dial at 980, for example, broadcasts using a signal that oscillates 980,000 times per second or has a frequency of 980 KHz. A station a little further down the dial at 710 broadcasts using a signal that oscillates 710,000 times a second, or has a frequency of 710 KHz. With a slice of the RF pie licensed to each broadcaster, the RF range can be neatly divided and utilized by multiple parties.
Every device in the United States that uses RF waves must conform to the Federal Communications Commission's (FCC) regulations. A baby monitor, for example, must operate using the designated frequency of 49 MHz. Cordless phones and other devices have their own designated frequencies.
