hi. i am beginner. i wanna run ar_sys package but i have a few problems.
i have usb cam or can i do that with my laptop's camera ?
**Firstly :**
"Fixed Frame No tf data. Actual error: Fixed Frame [world] does not exist"
probably my camera is not define to ROS. How can i do that ?
**Secondly :**
i try to run this line :
rosrun tf static_transform_publisher 0.0 0.0 0.0 0.0 0.0 0.0 map my_frame 100
But i have this error:
Fixed Frame [world] does not exist
**Thirdly :**
Have i to use special camera for ar_sys package ? (like we have to use lidar scanner in hector slam.)
