ABSTRACT:

     This project aims at designing and executing the gas sensing robot. This project aims at
sensing the presence of gas .Robot is defined as a mechanical design that is capable of
performing human tasks or behaving in a human-like manner. Building a robot requires
expertise and complex programming. It’s about building systems and putting together motors,
solenoids, and wires, among other important components. There are a number of subsystems
that must be designed to fit together into an appropriate package suitable for carrying out the
robot’s task. The gas detection scheme to be put into use is relatively free of false alarms, it is
anticipated that it will not overreact in non-smoke simulations. As mentioned earlier, the design
of the robot is according to specification of the contest. This robot is used in any location using
embedded based microcontroller concept.

        However, the microcontroller being used for the project has latched outputs and as
such one does not have to keep the buttons on remote control passed for more than a few
milliseconds. The working prototype of the gas detector including remote is designed using
micro controllers at both ends with appropriate code written in "C" language.

       The programming language used for developing the software to the microcontroller is
Embedded/Assembly. The KEIL cross compiler is used to edit, compile and debug this program.
Micro Flash programmer is used for burning the developed code on Keil in to the
microcontroller Chip. Here in our application we are using AT89C51 microcontroller which is
Flash Programmable IC.AT represents the Atmel Corporation represents CMOS technology is
used for designing the IC.
