OBJECTIVES This project deals with RF controlled Robot. It is used as fire extinguisher i.e. it sprinkles water on to fire It is a prototype for the “path finder” which was sent to mars
in 1998 This was a great achievement which detected the secrets of
MARS This can be moved forward and reverse direction using
geared motors and can take sharp turnings. When the robot is moving on a surface the system produces
a beep sound when metal is detected.
TECHNOLOGY/IDEA
RF robot can also be used as fire extinguisher i.e. it sprinkles water on to fire
RF is a frequency or rate of oscillation within the range of 3Hz -300GHz
The RF modules used here are STT-433 MHz Transmitter, STR-433 MHz Receiver, HT12E RF Encoder and HT12D RF Decoder.
The switches are interfaced to the RF transmitter through RF
Encoder.
If a switch is pressed then the motor gets switched on which in turn
switches on water sprinkler
TECHNOLOGY/IDEA
The encoder will continuously read the status of the switches, passes the data to RF transmitter and transmitter will transmits the data
This data will be received by the RF receiver As the TX requires a encoder, the RX also needs a decoder This project uses 9V battery
This project uses AT89S52 MCU as its controller.

ADVANTAGES
No line of sight
Not blocked by common materials. It can pass through solids
Longer range
Not sensitive to light
Not sensitive to weather conditions
DISADVANTAGES
Communication devices mostly use similar frequency so interference occurs if address is not specified.
High cost.
Data rate transmission is lower than wired transmission.
It cannot be work beyond limit
APPLICATIONS
Industries are using RF solutions
for monitoring, control , process, inventory tracking, data links and bar code reading devices.
Consumer products
electronic toys, home security, gate and garage door openers, Intercom, fire and safety systems, and irrigation controllers.
Medical products
patient call and monitoring, handicap assistance device, surgery Communication system, remote patient data logging and ECG monitor.
CONCLUSIONS
This Project presents a firefighting robot using RF communication and it is designed and implemented with Atmel 89S52 MCU in embedded system domain. Experimental work has been carried out carefully. The result shows that higher efficiency is indeed achieved using the embedded system. The proposed method is verified to be highly beneficial for the security purpose and industrial purpose.
FUTURE SCOPE
The practical application domains where robotic technology is most likely to be used are
Civil defence
Search and rescue, Fire fighting
Domestic services
like cleaning , arranging
Security/surveillance
patrol, observation etc.
War machines
Exploration(oceans,space,deserts etc.)
