Hi Prasanth,
PFB the link for Universities in Germany. Look for Mechatronics, Electronics and IT related fields. Remember, there might not be a course with Robotics as a general specialization but Mechatronics, Automation and IT are all linked and have extensive curriculum focus on Robotics.

Dear Darshak, have you enquired if diplomas are accepted? The basic rule to study in Germany is by completing 13 years education, and undergraduate diploma are not accepted. What you may do is by taking the Studienkollege program in a German university, its an assessment program of one year, you must take a final test at the end of the program. On clearance you can apply to the universities. I will advice please visit daad and uni assist websites. You have already decided what to study so look for the colleges and requirements on these portals.
Regards

Hello Sourbh, you must clear 13 years education, hence must take the Studienkollege program. Please visit DAAD website for details or you can see UNI ASSIST portal too. Alternatively you may complete the first year of an UG program in India and later apply for the bachelor degree in Germany.
Regards

If it is US, you must take GRE as well if you want to target to top schools.

Hi Rakesh,
University of Stuttgart, TU Darmstadt, Munich University of Applied Science, FH Aachen, TU Braunswick and Bremen University of Applied Science are some of the best. You may refer to QS World Rankings for more options. Scholarships are quite competitive in Germany though all universities have financial aid. You must have excellent grades to be considered for scholarships.

Its not mandatory but you may require it to interact among your peer group and professors. While choosing your university, do check if they offer mba in english or not before applying.
