OBJECTIVE

The robot is developed to give an alert when any fire

accidents occurs and to give alert when there is no

sufficient light. An advent of a new way of control using

mobile has been implemented in this project.

INTRODUCTION

In early days, robotic manipulators have been implemented indifferent control techniques like mechanical control and theremote control or tele-opertation. But with the advent of high

performance, a new way of control using mobile has been

implemented which is introduced in this project. The fire detection scheme to be put into use is relatively free

of false alarms, it is anticipated that it will not overreact innon-fire simulations.

The light sensor can be operated in two modes: with itsinternal red light source on or off. The light sensor is onlycapable of detecting absolute light intensity

The SensorsFIRE SENSOR:

Sensors were needed to detect vicinity of candle flame, exact

location of candle flame, and robots proximity to maze walls.

the robot would be able to sense an object in the front left,

front center, and front right. in order to detect the flame we

will need to calibrate it to detect the flame of a candle.

LIGHT SENSOR:

LIGHT DEPENDENT RESISTORS:

LDRs or Light Dependent Resistors are very useful especially

in light/dark sensor circuits.

BUZZER

A buzzer or beep is an audio signalingdevice, which may be mechanical, electro

mechanical, or piezoelectric. Typical uses of

buzzers and beepers include alarms, timers

and confirmation of user input such as a

mouse click or key stroke.

DRIVING CIRCUIT

DPDT RELAY:

DPDT stands for double pole double throw relay. Relay isan electromagnetic device used to separate two circuits

electrically and connect them magnetically.

GARE MOTOR

The direction the shaft rotates can be changed on most motors

by switching the right wires, there is usually a diagram on the

motor.

The direction of rotation is usually determined by viewing themotor from the shaft end and is designated as CW (clockwise)

orCCW (counter-clockwise).

FUTURE SCOPE

A practical fire and light sensing robot system must include a

collection of robots.

communicating and cooperating in the mission and system

requires facilities for going through obstacles in the presenceof fire.

CONCLUSION

Detects fire and light intensity.

To reach the current sensor network and mobile agent

technologies.

To replace the human with an automated mobile agent.
