I have recently completed my Bachelors in Computer science , i have no such exposure to ROS or any thing related to it

now i have been offered Internship in development in ROS should i go for it ?

My question is what are the mandatory prerequisite for ROS ?
and How much time it would take me to learn ROS ?

please also refer any guidance regarding ROS to learn it and get some overview of it

A prerequisite for ROS is the willingness to learn, a computer, and some time (6 months).

You'll want to start here:

I've always found the Conceptual Overview to be informative:

first thanks for your reply. Second ill be given 3 months of internship , within that 2 weeks would be given for training and self learning and after that ill be given small assignments ?

so would it will be achievable for any person very new to ROS ?

It's hard to answer. Everyone learns different things at different rates. You should be able to get talker listener working just following the tutorials in an hour or two. From there you can effectively use it but you won't be an expert until you've used it for a while.

It's impossible to give you a definitive answer to how long it will take you to get into ROS - depends how much you already know about coding, robotics, maths etc..., how enthusiastic you are and what you are trying to do.

Most nodes are written in C++ or Python.

Go to and go through Install, Overview and Tutorials. If you work full time on those you should be able to get them done in a couple of days. That will give you an idea of the infrastructure of ROS and what writing code might involve.
