Line following in ROS
Hi!
I was just wondering if there is any demo/tutorial on line following for ROS. I have a Turtlebot and I would like to mount a webcam on it and let it follow a line.
I found some line following algorithm for the Eddiebot, which is somewhat similar to Turtlebot. I am trying to make it work with the Turtlebot. Any hints and help are welcomed.
Being a rookie in ROS I don't know how to make this work in ROS and Turtlebot. Can anyone please help me here?
Maybe.. need to extract the line from image. If u have a camera model, u are able to get the relative coordinates of the line respect to your robot. feed it into global planner... Or u do not have a camera model, you can build a PID controller, make sure the line is perpendicular in the near end..
