NEED STATEMENT:

Rangoli is very useful to put in festivals because to attract the home with with beautiful and colorful and different types of designs. To save our time in festivals instead of putting Rangoli in hand we can make Rangoli making robot to save our time and enjoying the festivals with our relatives. For that purpose Rangoli making robot is very much essential for all of us.
