@Robotclub Hi, Since October, 2017, the LIDAR which comes with the TurtleBot3 gets the firmware that makes automatically run from booting on. It is not a malfunction. Look here: https://github.com/ROBOTIS-GIT/hls_lfcd_lds_driver/blob/262700c24f8701cf79d7da2e451899b70ddf5226/src/hlds_laser_publisher.cpp#L47 and hopefully (as Tully always says): ------------------------------------------------------------------------------------------------------------------------------------- The TurtleBot category here on ROS Discourse is the right forum for general discussions. For questions with direct answers or debugging please use http://answers.ros.org2 with the tag turtlebot or turtlebot3 with waffle or burger depending on your model. There are guidelines for asking questions at http://wiki.ros.org/Support1 ------------------------------------------------------------------------------------------------------------------------------------- Thanks Leon --- [Visit Topic](https://discourse.ros.org/t/lidar-of-turtleblot3-starts-spinning-once-power-on/3332/2) or reply to this email to respond.
