Running the code ???

[Abduoit]

Hi

I have question please,

When I run

roslaunch ur5_inf3480 ur5_launch_inf3480.launch sim:=false robot_ip:=10.0.1.3

I bring up the ur5, rviz and Moveit and everything looks fine , but I don't know if I am suppose to launch visp_auto_tracker separately ? since I don't see any launch for webcam that suppose to detect the qr-code,

if so, why it subscribes to /visp_auto_tracker1/object_position
not /visp_auto_tracker/object_position

Thank you
