<launch>
<node pkg="rosserial_server" type="serial_node" name="rosserial_server">
<rosparam>
  port: /dev/arduino
  require:
    publishers: [ status ]
    subscribers: [ cmd, lights ]
</rosparam>
</node>
<node pkg="rosserial_python" type="message_info_service.py"
    name="rosserial_message_info" />
