Wrong Topic Name?

[Che-Cheng-Chang]

Hello,

I try this system on my Gazebo Simulator.
And I found all the topic which published by your system nmaed '/drone0/ardrone/...'
But the topic released or received by ardrone 2.0 is 'ardrone/...'

That is, the subname '/drone0' is extra in the published system.
Is there any solution to solve this problem?

Thank you for your reply.
