Beforehand Robotics

I have watched plenty of videos for robotics, which in a result got me very much interested in this specific subject.
So, if I wanna pursue robotics as career & master this shit, what should i know beforehand i get into it ?
I know C,C++ & Java as languages, any other language to be known ?
I have read that you must know very detail about microprocessor & Microcontroller. also, you must know CAD-CAM & some mechanics basics & something like that ......

A detailed guide of which concepts should i clear before jumping into robotics will be highly appreciated 😀

Not sure if it will be useful, but I made some threads about robotics quite a while back, when I was a college kid.. I didn't complete the series as I wished to, but still, I think this provides a good intro at least, of what to expect in robotics. Do have a look..

Part-1
Part-2
Part-3

And as a side note, I would like to say, there is no beforehand and afterhand while learning robotics. Or learning anything, for that matter.

Just start with something.. Do some mistakes, learn and make them right.. Just do it.

Don't worry about languages and all, as of now. Since you are a CS engineer, I think you would have a good grasp of languages anyway. You might want to look at basic electronic circuits and components like diodes, transistors, relays etc.. and other discreet components. That would help you understand what is really happening inside the robot when you give a forward() or a stop() command through your programming language, whatever language that might be.

Thanks man for guiding 😀

Nowadays mechanical engineering is infiltrated so much by electronics and IT that areas like robotics have become mechatronics.
If you want to make a career in robotics , mechatronics is a must. If you are in India, the Centre for Artificial Intelligence and Robotics under DRDO, ministry of Defence, Govt of India have a good R&D facility in Bangalore.

In my opinion a grounding in mechatronics will be useful for any career in Mehanical Engineering production. Some background info is available in these links:
