Hello. I installed the zed-wrapper from http://wiki.ros.org/zed-ros-wrapper .

All set up was seems okay, the launch is not working on. (Regarding the server below, I replaced as *. )

nvidia@tegra-ubuntu:~/jetsonbot$ roslaunch zed_wrapper zed.launch

From this part, I have several error.

When I input this,

 $ roslaunch rplidar_ros rplidar.launch

it shows

[rplidar.launch] is neither a launch file in package [rplidar_ros] nor is [rplidar_ros] a launch file name
The traceback for the exception was written to the log file

However, if I input
