When I stop the launch on both rosbots the follower rosbot’s wheels don’t stop.
You probably use old firmware, because in new one, wheels will set automatic stop if they don’t receive any message with velocity information for a while.
I tried this rosservice call /stop_motor but I got ERROR: Service [/stop_motor] is not available. And the lidar didn’t stop.
You are right, I’m sorry for mistake. It’s not very elegant way, but after closing all launch file and
roscore you have to run
rosrun rplidar_ros rplidarNode it should give you Error and stop LIDAR.
Please let me know the results.
