Hello,
I am using the jackal from Clearpath robotics.
I have installed the required packages and drivers for the pointgrey camera.
I wanted to be able to use the camera in simulation environment with gazebo.
How do I launch the camera in the simulation environment.
I followed the instructions at:
http://www.clearpathrobotics.com/assets/guides/ros/ROS%20Navigation%20Basics.html#customization
These speak of using the custom urdf file for camera specs. But when I do a roslaunch after that, I get the following error:
Xacro conditional "$(optenv JACKAL_URDF_EXTRAS 0)" to: evaluated"/home/bru/dev/SensorFusionAndControl/BasicJackalNavigation/src/jackal/jackal_description/urdf/custom_example.urdf", which is not a boolean expression.
when processing file:
/home/bru/dev/SensorFusionAndControl/BasicJackalNavigation/src/jackal/jackal_description/urdf/jackal.urdf.xacro
while processing /home/bru/dev/SensorFusionAndControl/BasicJackalNavigation/src/jackal/jackal_description/launch/description.launch:
Invalid tag: Cannot load command parameter [robot_description]: command [/opt/ros/indigo/lib/jackal_description/env_run

Param xml is:
"param command="$(find jackal_description)/scripts/env_run $(find jackal_description)/urdf/configs/$(arg config) $(find xacro)/xacro $(find jackal_description)/urdf/jackal.urdf.xacro --inorder" name="robot_description"
The traceback for the exception was written to the log file
What am I not doing here?
Please help and advise.
Regards,
rsmitha.
