Simple ROS service examples

An example project (ROS node) that serves a virtual “song title database” via ROS can be checked out here:

git clone https://github.com/fairlight1337/ros_service_examples.git

This is just an example for reference purposes.

Running the server using

rosrun rosdemo_mp3 mp3_inventory

starts the title database server (C++ node, see src/mp3_inventory.cpp). This server serves album lists and according title lists (if requested) of everything stored in `pwd`/albums. So be sure to do

roscd rosdemo_mp3

before running the mp3_inventory node. The service type for communication is Mp3InventoryService.

The clients request a list of albums from the server. For each entry in this list, they request a list of titles.

For the C++ client, do

rosrun rosdemo_mp3 mp3_controller

. For the python client, do

rosrun rosdemp_mp3 mp3_controller_python.py

. For the LISP client, from within emacs, do

(ros-load:load-system "rosdemo_mp3" :mp3-controller)

and then execute

(mp3-inventory-interaction)
