This package provides capability to run the Text-To-Speech, Speech-To-Text and Skill functionality of Mycroft AI as ROS nodes providing topics, services and actions for communication.

The package makes use of the catkin_virtualenv library to run the Mycroft nodes within a seperate Python virtual environment


The dev_setup.sh can be used to install dependencies and configure the package for use.

Mycroft Setup

Mycroft can be configured using either ~/.mycroft/mycroft.conf or /etc/mycroft/mycroft.conf

Launching ROS Nodes

To launch all Mycroft nodes run mycroft.launch which will lanch the following nodes * mycroft_message_bus.py * mycroft_tts.py * mycroft_skills.py * mycroft_stt.py

roslaunch mycroft_ros mycroft.launch

Topics, Services and Actions


  • mycroft/speak (std_msgs/String) - String for Mycroft TTS to read
  • mycroft/utterance (std_msgs/String) - String to pass to the intent service of Mycroft
  • mycroft/speech (mycroft_ros/Speech) - List of Strings received from Mycroft STT
  • mycroft/remove_skill (std_msgs/String) - Path of skill to remove from SkillManager as a String ### Services
  • mycroft/register_skill (mycroft_ros/MycroftSkill) - Register the skill in the SkillManager ### Actions
  • mycroft/get_response (mycroft_ros/GetResponse) - Reads dialog before recording and returning user response
  • mycroft/ask_yesno (mycroft_ros/GetResponse) - Reads dialog before recording and returning "yes" or "no" based on user response ## Example ### Skill/Node Structure ROS nodes that are to be used as MycroftSkill's should be placed within their own directory with relevent 'vocab', 'dialog' and 'regex' directories to use for intents and entities ### Using the RosMycroftSkill The mycroft_ros Python module provides helper functions and classes for convenience such as the RosMycroftSkill which can be used to register a node as a MycroftSkill in the Mycroft SkillManager
