Revision history [back]

I've tried launching and recursive print statement occurred. However, I proceeded on by opening a new terminal n run Rviz. But rostopic list only returned:

/camera/rgb/points /goal /initialpose /rosout /rosout_agg /tf

and when browsing topic, nothing came out. Attached is the print screen. [okay but i don't have enough of this 'karma' thing in order to upload pictures. ): ]

Thank you.
