Like i was designing robot with my team few year back
Do you or anyone else on your team have any electrical/electronic qualifications?
From all the multitude of different questions asked here and on other sites with questions of the same ilk, it would appear you intend building or working on equipment that you only have the very vague notion of how it operates, I suggest if you intend to pursue these subjects in any depth with a view to occupation then somehow acquire some form of accreditation, coming to sites like this and asking the most vague of question, many requiring very extensive instruction is not serving anyone, least of all you..
If your location does not have any close technical institutions, a correspondence course would be the next best, and then come here with a particular question when you get stuck.
