It comprises of making the robot follow a color It comprises of making the robot follow a color contrasting strip(ie black on white and white on contrasting strip(ie black on white and white on black). This was done using a comparator circuit black). This was done using a comparator circuit using the IR led’s whose transmitted light is using the IR led’s whose transmitted light is being used in generation of signals in being used in generation of signals in photodiodephotodiode

This is based on the phenomenon that the This is based on the phenomenon that the status of signals generated by photodiode status of signals generated by photodiode change when it deviated from its pathchange when it deviated from its path

The comparator circuits were used for the The comparator circuits were used for the signal generated from photodiodes. The signal generated from photodiodes. The intensity of light from the IR led should be intensity of light from the IR led should be adequate for the current generationadequate for the current generation

the two ends of IR-receiver were connected the two ends of IR-receiver were connected to ground and positive terminal of the to ground and positive terminal of the comparator .comparator .

The output of these two were ORed and The output of these two were ORed and given to a mono-stable 555 timer given to a mono-stable 555 timer

The robot can be used as a guider to guide the visitors from the entrance .

It can help doctors to carry the medicines . It can rescue the people by extinguishing fire in

case of rescue missions. It can work in hazardous environments. It can be used in a nuclear power plant in case

of any leakage

In the present condition it can follow a single path way and not a crisscross one.

the robot could not be run through the batteries because at some conditions the current requirement for the circuit rises to about .8A which is very high and can not be obtained using batteries.
