Hey I have tried the following commands cd catkin_ws source devel/setup.bash roslaunch rplidar_ros rplidar.launch

I get the following results:

hello! I also meet the same problem. It seems like fixed in following way. Please locate your ROS workspace firstly. In my robot, the ros workspace is /turtlebot_ws re-init your workspace as following cammand :

$ cd ~/turtlebot_ws/src
$ catkin_init_workspace
$ cd ~/turtlebot_ws/
$ catkin_make

Then, please check rplidar performance by following command: $ roslaunch rplidar_ros view_rplidar.launch In my robot , the problem fixed. I hope it will help you. Have a nice day!

Hi, I tried this method but it did not work. When I do catkin_make the node.cpp and client.cpp are not made executable.... Any suggestions how to resolve this..
