Floating joints only exist on URDF, not on SDF (which is the primary description format used by Gazebo).

According to URDF documentation, a floating joint "allows motion for all 6 degrees of freedom". For SDF, that would be no joint at all.

Thank you so much for the information sir, kindly let me know, if there is a way to use a ball joint?

Not a "sir" ;) You could take a look at the following tutorial, a ball joint is used for the caster wheel: http://gazebosim.org/tutorials?tut=guided_b3 <- link

There is one more question, can we get ball joints by URDF? or xacro? what is the correct syntax for that?

Try the link now ;) That's a lot of questions in one, I suggest you start a new question for that.
