Hi Eric,
Many thanks for your advices and ideas.
As you already stated, whenever I use some other program to obtain the green led on the ROS node for Sicktoolbox Wrapper works without a problem. I have to say that this Pioneer/Sick configuration has to be turned on by activating through software and not only pushing a button.
I will try using a recursive launch file also.
Regards,
Renato.
