ERROR: Service [/spawn] is not available.
I have the following launch file:
<launch>
<node pkg="turtlesim" name="turtle" type="turtlesim_node"/>
<node pkg="rosservice" type="rosservice" name="spawnturtle1" args="call /spawn 2 2 -1 turtle2"/>
<node pkg="rosservice" type="rosservice" name="spawnturtle2" args="call /spawn 4 4 0.5 turtle3"/>
<node pkg="rosservice" type="rosservice" name="spawnturtle3" args="call /spawn 2 5 0.1 turtle4"/>
<node pkg="rosservice" type="rosservice" name="spawnturtle4" args="call /spawn 5 2 1 turtle5"/>
<node pkg="rosservice" type="rosservice" name="spawnturtle5" args="call /spawn 3 3 0.5 turtle6"/>
</launch>
I am getting the error as given in title, sometimes it spawns 2 turtle, sometimes 3 with the error.
Can anyone explain this weired behavior?
