Configure Rapp Manager for Robot

Description: describes how to setup rapp manager for the robot

Keywords: rocon app manager app_manager concert

Tutorial Level: BEGINNER

Next Tutorial: Bring up Rapp Manager

Goal

This tutorial shows how to configure a robot app manager launch for a standalone ros system. If you haven't already, make sure you have followed previous tutorial to install the rocon app platform or the full rocon

Launch Modules

The standalone.launch launches the core rocon app manager node as well as (optionally) a few highly correlated modules that work with the rapp manager. In the following list [C] indicates core modules and [O] optional modules:

Standalone.launch

In order to use rapp manager with your robot, you need to create your own launcher to bring up the robot and rapp manager. This is typical roslaunch file to bringup robot and rapp manager. Note that Capabilities and Zeroconf settings are hid for start template. Please check advanced tutorials to configure capabilities and use custom zeroconf setting.

Also please check turtlebot minimal.launch as an example. The list of arguments with full descriptions can be found here

You should replace the following arguments:

Please refer Add Your Robot Type Tutorial to use your custom robot type with app manager.

Also Please check out starter template in github to form your robot launcher.

Robot Identifier

Also note that robot_name and robot_type are used to form the robot's rocon_uri to filter out incompatible rapps.

Rapp Configuration

rapp_package_whitelist and rapp_package_blacklist would be the most important args. They controls where you can constrain the rapps on the ROS_PACKAGE_PATH that are discoverable by the rapp manager. For example, rocon_apps package includes default rapps like chirp or meta rapp to implement teleop rapp.

You need to add your rapp package in rapp_package_whitelist in order to use in rapp manager. To create and add your own rapp in the system, please refer to Create Your Own Rapp tutorial.

Interactions

Rocon Interactions are designed to manage client-side applications(e.g, QT, Android, Web App) in ros-ecosystem. Rocon App Manager makes use of rocon interactions to pair robot(or rocon) apps with client applications.

More details will be covered in Pairing Mode Tutorials later.

What's Next

Will be added later.
