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 as electrical engineers was to design and build a prototype system that could autonomously detect and extinguish a fire. Also aims at minimizing air pollution.
In this Project we design a Fuzzy based Microcontroller controlled Robot. It is the Robot that can move through a model structure, find a ?burning oil derrick? (lit candle) and then extinguish it with help of a Blower. This is meant to simulate the real world operation of a Robot performing a fire extinguishing function in an oilfield. Fuzzy logic provided an appropriate solution to the otherwise complex task of mathematically deriving an exact model for the non-linear control system upon which conventional control techniques could then be applied. The fuzzy inference system was designed to act as a PID-like controller.
We are using the Popular 8 bit Microcontroller the 8051 family Microcontroller. Program code to control the firefighting robot is written in embedded ?C? language.
I. Introduction to Flying Microrobots
Microrobotics is a rapidly increasing field of research and development which could be utilized in a wide range of operations including remote sensing, surveillance, chemical contamination detection, or reconnaissance. Miniature flying microrobots could be deployed from a safe location to investigate any situation that is deemed too dangerous or inaccessible to humans. Hazardousmaterial spill areas or radiation exposed environments could be sampled for contamination levels by an autonomous, disposable micro air vehicle (MAV) prior to endangering human investigators.
There are an abundant number of applications where MAVs could be used in a surveillance role. Imagine a MAV smaller than a house fly, virtually undetectable, and able to position itself to monitor conversations. Something so small could travel through ductwork in a building or delve deep into a cave to probe for information.
The vast realm of applications for nano and micro robotics is limited only by the imagination. Realizing these novel ideas on the other hand, is limited by current fabrication and design technology. As nano technology advances, many different sensors could be integrated into a MAV, giving it more functionality.
Very few people have fabricated flying robots on the 10-centimeter scale and even fewer on the millimeter scale. No man-made flying devices exist today that are truly on the micro scale, less than 1 millimeter. By convention, the largest dimension of a robot determines its size scale, not its smallest feature size.
