Hi @MeineLiebeAxt ,

I had the same problem.  
The laser scanner mounted on the robot in the rosject is a 360 degree laser scanner.  
So 0/719 is back, 180 is right, 360 is front, and 540 is left.

Refer to this post: [Incorrect Robot Scan Values in ROS Basics Course - Wall Follower Robot / TurtleBot3](https://get-help.robotigniteacademy.com/t/incorrect-robot-scan-values-in-ros-basics-course-wall-follower-robot-turtlebot3/18688)

Just do a `rostopic echo /scan -n1` to get more info about laser scanner values if you are unsure of device properties.

Regards,  
Girish
