Hello all,

I want to connect my arduino to ROS and I follow the instructions on this page: http://www.ros.org/wiki/rosserial_arduino/Tutorials/Hello%20World and I have an error messages when I run this command

rosrun rosserial_python serial_node.py /dev/ttyACM0

I got these messages:

You need to `source` the `setup.bash` in the ros workspace where you installed rosserrial package (I installed rosserial from source in my own workspace, as explained [here](http://wiki.ros.org/rosserial_arduino/Tutorials/Arduino%20IDE%20Setup#Installing_from_Source_onto_the_ROS_workstation)).

Wow I found another solution, the one provided did not work for me! After setting thins up on three different pieces of hardware i finally found out it was a file that needed copied from src to main ros location here is the command i used please replace the username <username> with yours. Also you must complete the groovy rosserial setup!

sudo cp -i /home/<username>/catkin_ws/src/rosserial/rosserial_python/src/rosserial_python/SerialClient.py /opt/ros/groovy/lib/python2.7/dist-packages/rosserial_python/

goodluck so for this is not working great but it works yeah... no more
