Hello, I’ve tried to move my turtlebot3 with the e-manual that is below link from robotis web page.
https://emanual.robotis.com/docs/en/platform/turtlebot3/autonomous_driving/#autonomous-driving

I finished from bring-up to slam and navigation manual. It worked well.
But I’m now trouble in doing autonomous driving section.
I did camera calibration but It didn’t work well.
I got error like this.

[ERROR] [1612166649.572207]: bad callback : <bound mehthod Detection.cbFindLane of <main.DetectionLane instance at 0x7f037081c638>

Actually I don’t know what is main reason for this problem.
I wanna solve this. How to solve and move it following the lane?

Thank you.

Hi,

I would suggest to first try it in simulation in a ROSject or locally to see if its related to the Hardware setup or its the lane following software for some reason.

Thank you for your recommendation.

Hi,

Haven’t done that setup. Maybe if you post here the errors we can have a look.
