  • 3. 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.
  • 4. 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
  • 5. 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.

  • 11. 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
  • 12. 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
  • 13. APPLICATIONSIndustries 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 garagedoor openers, Intercom, fire and safety systems, andirrigation controllers.Medical products patient call and monitoring, handicap assistancedevice, surgery Communication system, remotepatient data logging and ECG monitor.
  • 14. CONCLUSIONS This Project presents a firefighting robot usingRF communication and it is designed andimplemented with Atmel 89S52 MCU in embeddedsystem domain. Experimental work has been carriedout carefully. The result shows that higher efficiencyis indeed achieved using the embedded system. Theproposed method is verified to be highly beneficialfor the security purpose and industrial purpose.
  • 15. FUTURE SCOPEThe 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.)
