Connecting wires. Robots are also useful to do jobs in areas and in situations that are hazardous for human. The Receiver Board :- This project outlines the strategy of establishing wireless 1. Arduino board. The main 2. Breadboard and connecting wires.

The detected 4. LD motor driver chip X 2 Each chip controls 2 motors bi-directionally. Our motive is to implement the fundamental concept of 8. A 9V battery for powering the Arduino on the Rx end. The remote control application of RF has been extended to operate a bot. The main Robot Chassis and Drive Train:- aim of the project is to implement a wireless robot which can 1. Robot chasis. Wheels X 4 of fire and chemicals. In this project we will use a Mhz Tx Sensors:- and Rx pair to allow the Arduinos on both the ends to 1.

HC-SR04 communicate wirelessly with each other. Here the Robot can 2. HUB detect the obstacles through the use of ultrasonic sensors. Apart 3. MQ-2 from this the Robot can detect flames of fire through the use of flame sensor. Also it will be able to detect chemicals likeH2, III. The robot will be able to implement one of these three functions at a time. Arduino MEGA board. Chemical sensor: The MQ series of gas sensors use a small heater inside with an electro-chemical sensor.

They are sensitive for a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino. The MQ-2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, i-butane, propane, methane, alcohol, hydrogen and smoke. Offers productivity, convenience and cost advantage over traditional wired technology. Block diagram 3. No need for manual retrieval of data. Availability of real time data.

The superior nature of this scheme depends on many environmental factors, such as operation The operator gives the commands through the controller scenarios, specific data types etc.

The code which is programmed into Arduino reads 2. More research work needs to be done in whenever a button is pressed since the corresponding digital future to find the respective application scenarios for pin goes LOW. The Arduino generates a signal depending on this scheme with all the related factors taken into the command given and this signal is then given to the consideration.

This technique needs to be transmitter module Tx which transmits the command. The implemented in a wireless sensor network with transmitter module has four pins namely Ant, Vcc, Data, Gnd. Reception process:- The transmitted command is received at the receiver end by the receiver module Rx which is interfaced to another VII.

GND:-This Pin 20 is the ground pin. Since the input to the internal clocking circuitry is through a divide- by-two flip-flopso there are no requirements on the duty cycle of the external clock signal,but minimum and maximum voltage, high and low time specifications must be observed.

The A. Flash programmable and erasable read only memory B. There are two data harmonious with the industry-standard MCS instruction pins are provided in the receiver module. Thus, this data can set and pin out.

The program memory is permitted to be be used for useful applications. By using either a variable supply voltage or by changing the strength of current in its field windings the speed of DC motor can be controlled over a wide range. Small DC motors are used in Fig. The STT is ideal RF transmitter for remote control applications where low cost and longer range is requisite.

The transmitter operating supply voltage ranges from 1. The transmitter employs a SAW-stabilized oscillator, which ensures accurate frequency control for best range Fig. The STT is suitable for high volume F. Push Buttons: applications because of its manufacturing-friendly SIP A push-button or simply button is a simple switch style package and low-cost.

Buttons are usually made out of hard material, D. Metal Detector Circuit: The metal detector consists of an oscillator which produces usually plastic or metal. The surface is generally flat or an alternating current that passes through a coil producing shaped to hold the human finger or hand, so as to be easily an alternating magnetic field and it is the simplest form of a depressed or pushed. Buttons are generally of two types. If a piece of electrically conductive metal The most often are biased switches, though even many un- comes close to the coil, eddy currents will be induced in the biased buttons due to their physical nature require a spring metal, and this develops an alternating magnetic field of its to return back to their un-pushed state.

Different terms are own. The change in the magnetic field due to the metallic used by different people for the "pushing" of the button, object can be detected by using another coil to measure the such as press, depress, mash, hit, and punch.

These magnetic field acting as a magnetometer. DC motor: It is a class of electrical machines that converts direct Fig. To periodically change the direction of This robotic vehicle uses HT12E Encoder which converts 4 current flow in part of the motor nearly all types of DC bit data to serial output which is then fed to the radio motors have some internal mechanism which are either frequency transmitter module for transmitting the same to electromechanical or electronics.

Most types of DC motor be received by the receiver radio frequency module the produce rotary motion; a linear motor unswervingly output of which is fed to HT12D the serial decoder IC, the produces force and movement in a straight line. The transmitting end of controller is attached to a set of www. When a fastidious button is pressed They are used in airports and building security to the program executed delivers consequent 4-bit data which detect the artillery.

The data so received at the receiver end of port 1 control the motor through motor VI. The transmitter is supplied by frequency communication with wireless audio transmission a 6v battery in series with a silicon diode to finally develop and it is designed and put into maneuver with Atmel 89C51 required voltage for microcontroller circuit.

The receiver is MCU in embedded system field. The robot is moved in power-driven by a 12v battery in series with a silicon diode finicky track using switches and the Beeping sound is to guard the circuits from unintentional reverse battery generated.

Experimental work has been carried out connection. The outcome shows that higher effectiveness is IC is fed to the controller, decoder, and the motor indeed achieved using the embedded system. The proposed driver IC LD pin 8 for operation of the motor. A metal method is demonstrated to be highly favorable for the detector circuit is used that uses a tuned circuit comprising security intention and industrial purpose.

The sensitivity of problem notwithstanding its extension, meeting the which is familiar by a potentiometer of 5k. The output of specification required for the mine recognition sensor. It this resonant circuit is fed to Q2 which quarter in emitter contributes to the enhancement of detection rate, while follower configuration with appropriate filtering to forward upgrading the operability as verified by completion of all bias Q3 that forces Q4 to be not in condition stage thus the the detection job as scheduled.

Desktop doc Robots are used for sense the minerals present in the ground. These robots are used for detect the bombs. These can be used in construction industry for situate steel bars present in concrete.
