From the last chapter we saw that Madara has the ability to channel his will to another person.
we can see that by using black rods Madara channel his will to Obito.
The same thing happened with Nagato when he summoned Gedo mazo.
He has already arranged those blackrodes in the gedo mazo ?????????
So Madara wanted Nagato to became evil.He gave Nagato the rinnegan. Rinnegan users can summon gedo mazo. Madara would have know that when Nagato loose important person and he will feel hatred.So Nagato will summon gedo mazo and blck rodes penetrate his body and make him mad.If we examine how Obito became evil we can see that the black rods penetrate Obito's body and channel Madara's will or hatred.
So in the beginning when Madara first summoned gedo mazo it don't have any black rodes. The black rodes are which channel Madara's will or hatred.
