Cannot launch node of type, ROS Error
Hey i get the following Error: ERROR: cannot launch node of type [arbotix_python/arbotix_driver]: Cannot locate node of type [arbotix_driver] in package [arbotix_python]. Make sure file exists in package path and permission is set to executable (chmod +x)
Does someone have an idea? if i locate arbotix_driver i get this :
/opt/ros/melodic/lib/arbotix_python/arbotix_driver
my launch file:
<launch>
<node name="arbotix" pkg="arbotix_python" type="arbotix_driver" output="screen">
<rosparam file="$(find realleg2)/config/realleg.yaml" command="load" />
</node>
</launch>
and the yaml file:
port: /dev/ttyUSB0
read_rate: 10
write_rate: 10
joints: {
servo1: {id: 1},
servo3: {id: 3},
servo5: {id: 5},
}
i also tried to reinstall and used catkin_build and source devel/setup.bash but still get this error...
I use ROS Melodic, Ubuntu 18
Thanks, Eddy
