Hey all,<br><br>roscpp and rospy both provide ways to remove ROS specific arguments from the argument list.<br><br>For roscpp its removeArgs: <a href="http://www.ros.org/doc/api/roscpp/html/namespaceros.html#aa044af6270e37edd78cf05f5fc7ee148">http://www.ros.org/doc/api/roscpp/html/namespaceros.html#aa044af6270e37edd78cf05f5fc7ee148</a><br>

I ran into this problem too. Roslaunch seems to be prepending 2 arguments to the argument list, though I don't remember what they are right now.<div><br></div><div>I've resorted to avoiding arguments altogether, preferring to use parameters, though perhaps this is not the best method.</div>

I can't test this right now, but I encountered this before, and this<br>
is what I remember. When I did something like this:<br>
<br>
<node pkg="x" type="y" name="z" args="ARG" output="screen"/><br>
<br>
This would start program y with 4 arguments, the 4th of which is "ARG"<br>
<br>
however, if you do "rosrun x y ARG"<br>
<br>
this would pass 2 arguments to the program, the 2nd being ARG<br>
