i am new to ros and am trying to localize swarm robots using normal webcam so i found whycon
i am following the tutorial
https://github.com/lrse/whycon/wiki/Tutorial
but nothing happen and i dont know how to debug that
iam sure that
1)my camera publish images on the topic /usb_cam/raw_image
2)the image processing node publishing image on topic /usb_cam/image_mono ....etc
the whycon publishing the pose
but when i am trying to echo the /robot_pose or the /image_out i have nothing on the screen no error message no output
what should i do ?
