Not getting any messages passed to the laser subscriber for part 1 of the first course project. When I launch the simulation and can manually control the turtlebot, I run the command rostopic echo /LaserScan and get the result: WARNING: topic [/LaserScan] does not appear to be published yet. I am using almost the exact same code as the first topics quiz which worked fine. Any ideas why I can’t get a laser reading?

Hi @tomseymour ,
Do you mean the rosject that contains the real robot project?
- ROS Basics Real Robot Project
If so, the correct name of the laser topic is /scan
Please, let me know if that solves your issue
Yes thank you that worked I was still subscribing to /kobuki/laser/scan
