FIRE FIGHTING ROBOT

Abstract :- This synopsis describes the design and construction of a small autonomous Fire Fighting Robot. At the heart of the system is the ATMEGA30 microcontroller ATMEL. The program code to control the fire fighting robot is written in C language. This is because it is user friendly language and easy to understand. The system consists of two optically isolated stepper motors for precision movement. Furthermore, the robot performs analog to digital conversion on 6 infrared sensors: 4 for wall proximity detection, one to detect floor markings, and one for candle detection. The 4 proximity sensors utilize heterodyne modulation of the IR signals to reduce the effects of ambient lighting. The extinguishing system is comprised of a large fan salvaged from a toy hovercraft, and a 3.5 kHz tone decoder circuit is used to start the robot reducing all the human intervention and making the robot fully autonomous. This mini project model is meant to simulate the real world operation of a robot performing a fire protection function in an actual home. The candle represents the fire which is just started at the home which the robot must find first and then extinguish.

VEHICLE NUMBER PLATE DETECTION

Abstract :- Number plate detection is a technique of image processing and character recognition system to identify vehicles by automatically reading their number plates. In this work an intelligent real time On Line number Plate detection System which caters to the need for intelligent traffic management system, in order to cope up with constantly increasing traffic on today's roads has been developed. Number plate detection (NPL) algorithms in images or videos are generally composed of four processing steps, namely, Image acquisition, Number plate detection and extraction Character segmentation, is done through fusion of spectral analysis and connected component analysis, and Character recognition is done using support vector machines.
