About

The rovio_av package contains nodes and launch files that can be used to stream video and play sounds on the Rovio. Additionally, included in the rovio_av package is a selection of .wav files that have been converted to 8000 Hz 16 bit PCM (the native format for the Rovio). These files are conversions from Willow Garage's Robot Sound Libraries. These sounds can then be sent to the Rovio via a service call and played on its internal speakers.

Nodes

rovio_audio

rovio_audio can be used to play 8000 Hz 16 bit PCM .wav files on the Rovio. Additionally, included in the rovio_av package is a selection of .wav files (located in the wav directory) that have been converted to 8000 Hz 16 bit PCM (the native format for the Rovio). These files are conversions from Willow Garage's Robot Sound Libraries.

Services

wav_play (rovio_shared/wav_play)

Send the given file (given as the absolute file name) to the Rovio to play.

Parameters

/rovio_shared/host (string)

Hostname used to communicate with the Rovio.

/rovio_shared/user (string)

Username used to authenticate with the Rovio.

/rovio_shared/pass (string)

Password used to authenticate with the Rovio.

Installation

To install the rovio stack, you can choose to either install from source, or from the Ubuntu package:

Source

To install from source, execute the following:

```
   1 cd /path/to/your/ros/stacks
   2 git clone https://github.com/WPI-RAIL/rovio.git
   3 roscd rovio
   4 rosdep install rovio
   5 rosmake rovio
```

Ubuntu Package

To install the Ubuntu package, execute the following:

```
sudo apt-get install ros-fuerte-rovio
```

Startup

The rovio_av package contains a rovio_av.launch file which should be edited with the hostname, username and password to login to your Rovio. Additionally, the username, password, and host should be changed in the GSCAM_CONFIG variable in order to stream video using gscam. This file launches an instance of the rovio_audio and gscam nodes. To launch these nodes, the following command can be used:

```
roslaunch rovio_av rovio_av.launch
```

With the above nodes running, you can test video streaming with the image_view package using the following command:

rosrun image_view image_view image:=/gscam/image_raw

Additionally, an example to test the audio service is the following command:

rosservice call /wav_play /path/to/rovio/rovio_av/wav/G22.wav
