             The need for a device that can detect and extinguish a fire on its own is long past due. Many house fires originate when someone is either sleeping or not home. With the invention of such a device, people and property can be saved at a much higher rate with relatively minimal damage caused by the fire. Our task is  to design and build a prototype system that could autonomously detect and extinguish a fire.             The system uses a fire detector module which gives analog output voltage according to the intensity of fire.The detector is rotated through 180 degree using a servomotor which gives wide angle for detection.When fire is sensed,the Robot is redirected to the position of fire and the pump is turned on.Water is pumped till the sensor detects no fire.

This post will provide you with the basic information on how a remote controlled vehicle can be constructed. Read on to know more about this. The components required to construct the vehicle is listed below: 1.2Ghz 1000mW Receiver+Transmitter USPS Priority Mail boxes Hitec Optima 6 2.4Ghz Receiver Arrowind 18A Brushless Speed Controller 2200mAh 20C LiPo Battery Pack Brushless motor Custom motor-reversing relay board Foam wheels 7-Inch Handheld LCD TV Servo The first thing to do here is to test the wireless transmitter. All the required components are mounted on the USPS mail box. Once the test is done, the box is strapped onto a nitro RC truck. The vibrations caused prevents the truck to be driven via the wireless video feed. The best thing to do in this case is to add wheels and propulsion to the box.
