Encountering an error while launching corobot_software.launch

[raghulshanmuganathan]

Hi,
I have Corobot CL2 bot. I am encountering an error while trying to launch the GUI.

while giving the following command
roslaunch corobot_launch corobot_software.launch

I am getting the following errors:

ERROR: cannot launch node of type

Thank You.

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?

[CandidCypher]

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.

[raghulshanmuganathan]

@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

[raghulshanmuganathan]

@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.
