Encountering an error while launching corobot_software.launch about corobot HOT 6 CLOSED

Hi @raghulshanmuganathan are you sure your ROS environment is setup correctly and you have sourced setup.bash in the catkin workspace that contains the corobot package? Did the corobot packages compile successfully?

from corobot.

I would agree with @sterlingm; sounds like you don't have the stack properly sourced if it is not finding them in the /opt/ros/.... directories. When you Catkin init a workspace, it should add/link it to the source file.

@sterlingm Yes, I compiled the packages and got no errors while building. I have already sourced setup.bash.
I wonder how the individual nodes can be executed, but launching a launch file throws an error.

for example,

I could run PhidgetMotor node using rosrun command. But while I try to launch the launch file in the same package, I got similar error.

Thanks for your response.

@raghulshanmuganathan The corobot_software.launch file just launches a few other launch files you can find in the launch_include directory. Can you launch those individually? Try

roslaunch corobot_launch motors.launch
roslaunch corobot_launch general.launch
roslaunch corobot_launch phidget_sensors.launch

and see what happens. Also, can you tell us:

• What OS you're running
• Which version of ROS
• The output of "env | grep ROS"
• Whether or not you can launch any ROS launch files, both from shared ROS packages and 3rd-party packages

from corobot.

@sterlingm I am not in lab right now. But I could remember that I got the same error while launching motors.launch. other launch files works fine in that directory.

OS: ubuntu 12.04
ROS Version: Groovy

I will respond to your other queries by tomorrow morning.

Thank you.

@sterlingm & @bleucanary Everything works fine now...
Thanks for your response.
