ROS - Android Assistant App.

An application to send messages to ROS using your voice.

Build and install

Build and install the app with Android Studio.

Using the app

The first screen requests a master URI to connect to a ROS Master. Write the $ROS_MASTER_URI in which the master is running and press the connect button.

Topics

The base topic can be set in the settings page. E.g. if we chose the topic "goal_assistant" and namespace "create1", this will produce the following:

• /create1/goal_assistant: topic used to publish Vector3 messages with the goals commanded by the app.
• /create1/goal_assistant_cancel: this is used to publish a message to cancel the current goal, when a "stop command" is executed.
• /create1/goal_assistant_distance: the app subscribes to this topic to display the remaining distance to the current goal, in meters.
• /create1/goal_assistant_result: the app subscribes to this topic to display the action results.

Communicating with move base

To control a robot using move base, this package is required.
