In your opinion is robotic engineering is a good field for girls to go or not because i really want to become a robotic engineer but some of the people say that it is not a good career to choose and specially for girls.

I don't understand why you think it matters whether you are a girl when it comes to deciding on a field of study. I know lots of women engineers, but if anything we need more, not fewer, women engineers. As for robotics - it's a fine field of study, and the experience you gain in learning about mechanical, electrical, an computer engineering will give you an opportunity to go into any of those fields after you graduate. As an example, my nephew studied robotics at MIT and ended up designing helicopters.
