camnode launch file fails #34

Closed llorban closed 6 years ago

llorban commented 6 years ago

I created the following launch file:

<launch> <rosparam command="load" file="$(find freemoovr_arena)/launch/flydra.yaml" /> <node name="AVT-02-2020C-07056" pkg="ros_flydra" type="camnode2-pylon" args="--camera-name=AVT-02-2020C-07056 --http-server-addr=127.0.0.1:4011 --ros-tracking-start-delay=30"> </node> <node name="AVT-02-2020C-07058" pkg="ros_flydra" type="camnode2-pylon" args="--camera-name=AVT-02-2020C-07058 --http-server-addr=127.0.0.1:4011 --ros-tracking-start-delay=30"> </node> </launch>

which results in the following error:

flightlab@ubuntu:~$ roslaunch /home/flightlab/ros/flydra-kinetic/src/ros_flydra/launch/prosilica1.launch ... logging to /home/flightlab/.ros/log/f1867084-65f2-11e8-b48b-000c2967883e/roslaunch-ubuntu-95368.log Checking log directory for disk usage.

It looks to me like the problem is this line: <rosparam command="load" file="$(find freemoovr_arena)/launch/flydra.yaml" />. You are telling ROS to look for the yaml file in the freemoovr_arena ROS package, which is not found.
