Choreonoid is an open-source, lightweight, and extensible integrated graphical framework for robot development. You can develop your robots with various functions and resources of Choreonoid.

Choreonoid works as a visualization tool. The provided GUI tools support editing model files, checking self-collisions, and calculating forward/inverse kinematics. Additionally, you can visualize sensor data, including camera images, point clouds, and forces/torques, on Choreonoid.

You can simulate the dynamics of robots and environments on Choreonoid. Light-load and accurate simulation environments accelerate your research and development on robot planning and control. Since the default physics engine is robust for contacts, Choreonoid has been utilized in the research on humanoid robots for over a decade.

Choreonoid provides a function for choreographing robot motions. Visualization tools and dynamics engines strongly support your motion editing. As an example, Choreonoid enabled the HRP-4C humanoid robot to dance with human dancers in 2010. You can see the video here.

Choreonoid has been used in various situations. Application examples are shown in the following figures and the fields of application range from research to industry and entertainment. One of the advanced features of Choreonoid is extensibility, so you can easily add your own plugins suitable for your project with plentiful resources provided by both Choreonoid and third parties.

To install Choreonoid, please see the installation page on the official document

ROS (currently, only ROS1) is supported. Please see our official document to set up Choreonoid with ROS.

Choreonoid project is led by Dr. Shin'ichiro Nakaoka. After the start of the project in 2006, Choreonoid had been developed at National Institute of Advanced Industrial Science and Technology (AIST), Japan, until 2019. Currently, Choreonoid Inc. maintains this project.
