Hi,

My question is: when the .launch file is launched by using robot_upstart set up, does it have root access? I have not tested yet because my package it not ready. Our project uses a headless robot, and there is a package that would use the PRU of the Beaglebone. At the moment, we need to do rosrun from root, in order for this package to work. If the answer is no, could you please suggest some solution to us?

Best regards,

Nhan Nguyen

You can make one node of your launch run as root - using launch-prefix - while keeping the rest running as user. Here is an example launch file:

<launch>
<node pkg="i2cpwm_board" name="i2cpwm_board_node" type="i2cpwm_board" output="screen" launch-prefix="sudo -E ">
</node>
</launch>

In this example, we need root access for the I2C device on a Raspberry Pi.
