how we can combaining a object following robot with a obstucle avoiding robot?

[MrWizard]

some ir- or ultrasoon sensors and a transmitter (object to follow) / receiver (follower) with multiple antenna's.
Or perhaps reflector (object to follow) based. Laser guided ?

First tell us more what the situation is, it is all up to the surroundings and the capability's it needs to have.

Sir we want to make a robot that follows us and avoids any obstucle between us and robot.Can we use an IR transceiver module?

[MrWizard]

All depends on the speed. First of all write down a framework of operation. If all the demands and questions are clear you can fill in the details. Then you start selecting the hardware and start programming.

Out of the blue starting with hardware can give you good result but no garantee to get to your point of destination. Just as a following robot with obstacle avoiding capabilities.
So if the details and demands are not clear in your head, how can we give you a decent answer ?

It very important to know the problem. If you say your bot will follow a line and once the obstacle comes it will avoid it. You have to think that once the bot avoids the path(line) because of the obstacle how it is suppose to come back to the line and follow it.
There is a very greater problem(path planning) which will be solved with very complex alogos.
