a) Mr. Dixon commented and wanted me to change the black background. So, changed background, hope he will like.
But I cannot write in detail like he has written.
b) Now disappointing news : Due to my financial limitations, I wont be able to purchase motor and other things which could look my project as good as others.
But I have thought to do still go through the competition & instead withdrawing,I will try to make my post and outcome as good as possible. So, I have decided will work in those limitations of hardware and with given "Challenger's kit" and also will do MATLAB modelling of my project.
