ros2d2 is a ROS package to make R2D2-like sounds. It is based on the following libraries:

• r2d2-voice to synthesize prametric beep sounds (like whistle)
• ttastromech to transform texts into R2D2 sounds

Installation

pip install ttastromech

cd ~/catkin_ws/src
git clone https://github.com/koide3/ros2d2.git

cd ~/catkin_ws
catkin_make -DCMAKE_BUILD_TYPE=Release

You may need to install libasound2-dev:

sudo apt install libasound2-dev

Usage

roslaunch ros2d2 ros2d2.launch

# play a preset beep sound
$ rostopic pub /ros2d2_node/preset std_msgs/String "data: 'whistle'"

# generate R2D2 sound from a text
$ rostopic pub /ros2d2_node/speak std_msgs/String "data: 'hello world'"

Audio: whistle, hello world

Topics

/ros2d2_node/preset

You can play preset beep sounds synthesized by r2d2-voice. Default preset sounds are; whistle, tonedown, toneup, failure, alert, confuse, and calculate. They are defined by a csv file at ros2d2/data/presets. You can add new sounds by adding commands to the file.

/ros2d2_node/speak

With this topic, you can play R2D2 voice transformed from a text using ttastromech. It makes sound by translating each character in the text to corresponding predefined R2D2 sound.

/ros2d2_node/cmd_synth

This is a topic to make sound by directly giving commands to r2d2-voice. See r2d2-voice for the details of the command.
