Hi, I wanted to ask about an issue I'm having with the lidar of the TurtleBot3 burger. I've noticed that sometimes it doesn't start when I launch the controllers with turtlebot3_robot.launch, and it also turns off randomly after it works for a while. I also saw that I think the green light on the board controlling the lidar (between RPi3 and OpenCR) indicates that the lidar should be turning, but sometimes it's on and the lidar does not turn. When this happens, I can still see the /scan topic being offered but it's empty. I also saw that the issue goes away (although only for some time before it comes back) if I unplug and plug back the lidar from the RPi3's USB port.
Does this have a fix? How do I make sure it's not a hardware issue?
I'm sorry about the delayed reply.
Please keep track on the GitHub issue thread.
