Hi,
I am following https://emanual.robotis.com/docs/en/platform/turtlebot3/autonomous_driving/ this page for learning turtle bot3 with ROS.
after setting up intrinsic and extrinsic camera ,I started lane detection part. and I ran roslaunch turtlebot3_autorace_driving turtlebot3_autorace_control_lane.launch command,it's giving error. I placed robot in the middle of yellow and white line . and it's moved very well till it reached the round.when reached the round in the map ,robot got confused and moved wrongly.
