[ros-users] linking 2 urdf models

Hi all,

I am currently trying to display in Rviz a model of my hand, attached to
a robot arm.

I have the hand urdf model, that works perfectly well, and the arm urdf
model, that works fine too.

But I cannot manage to display them together.

Is there a way to "attach" the two models, for instance setting the
origin of the hand at the end of the arm ?

Thanks in advance.

Cheers,

Nicolas
