AIM OF THE PROJECT
Constructing a robot that has the ability to scan the entire
landscape
 While doing so it should help us in preparing a !irtual blue print o"
the area so that security personnel can be absolutely sure that the
#hole place has been scanned$
The robot should be co%bat oriented
It should be designed to reduce casualties

)A' 'E('OR'
MQ-5 is used for combustible gas detection. Can detect the presence and concentration of
gases like methane, propane and butane. The sensing element used is SnO2. esistance of SnO2 !aries in the presence of gases. "t is a si# pin de!ice, $ith a integrated heating coil. Sensiti!it% of SnO2 is greater at higher
temperatures. The suppl% !oltage is 5& 'C. The output !oltage proportional to the gas
 
MOTOR -RI4E
The pro:ect uses -C %otors "or robot$ -C %otors ha!e polarity and direction o" rotation
depends on direction o" current$ Hence "or bi2directional %otor rotation a H bridge

#hich direction o" current can be changed using control signals$
The pro:ect uses IC +87 "or i%ple%enting H bridge dri!e$
 
0'* I(TERFACE

Hence an inter"acing circuit using FT-& chip is built to con!ert 0'* signals into 0ART signals and !ise !ersa$
