The robot can be used as a guider to guide thevisitors from the entrance .
It can help doctors to carry the medicines .
It can rescue the people by extinguishing fire incase of rescue missions.
It can work in hazardous environments.
It can be used in a nuclear power plant in case ofany leakage

In the present condition it canfollow a single path way and not acrisscross one.
the robot could not be run throughthe batteries because at someconditions the current requirement
for the circuit rises to about .8Awhich is very high and can not beobtained using batteries.
