We are currently doing a survey on robot description formats and the user experience of ACDC4Robot. It would be very appreciate for you to fill in the questionnaire.
Robot description format (RDF) contains information about robot model which is required by simulation, visualization, planning etc. In this project, we provide a Fusion360 Add-In for generating robot description files automatically from robot design.
Currently, this Add-In supports exporting URDF, SDFormat, and MJCF. URDF (Unified Robotics Description Format) has been the most widely used robot description format, but has several limitations and lack of update. SDFormat (Simulation Description Format) has more features than URDF, such as supporting closed loop chain mechanism. SDFormat has been a seperated project from Gazebo aims to be a simulator indenpendt format but still not as popular as URDF. MJCF is a robot description format used in simulator MuJoCo and has been support by more simulators such as Nvidia Isaac Sim. It also has more features then URDF to provide more robotic system information. Other robot description formats might be supported in the future.
Also, we provide a Fusion 360 robot model library that can be used out-of-box for design, simulation, and learning. 👉🤖Fusion 360 Robot Library
Export robot description files from Fusion360 design file directly with GUI panel.
- Supported robot description formats:
- An robot model library including various robot types:
- Robot Arm
- Gripper
- Mobile Robot
- Quadruped Robot
- Humanoid
You can install this Add-In form Autodesk Fusion app store or manually.
You can download ACDC4Robot from Autodesk Fusion App Store, Windows and Mac version are provided.
Due to the review process of app store, ACDC4Robot at app store might not update in the same frequence as this repository. So updates such as new features and bug fix might be late for ACDC4Robot app store version.
Download and copy /Add-IN/ACDC4Robot folder into Fusion360's Add-in directory which can be found at Preferences -> General -> API -> Default Path for Scripts and Add-Ins.
In default it should be at:
Windows:
%appdata%\Autodesk\Autodesk Fusion 360\API\AddIns
Mac:
$HOME/Library/Application Support/Autodesk/Autodesk Fusion 360/API/AddIns
or it can be found at Preferences -> General -> API -> Default Path for Scripts and Add-Ins.
After installation for the first time, use Shift+S or click UTILITIES -> Add-Ins -> Scripts and Add-Ins to open Scripts and Add-Ins window.
Find Fusion2Robot at Add-Ins -> My Add-Ins, select Fusion2Robot and click Run(for normally use, please select Run on Startup). Then the icon will appear beside UTILITIES -> Add-Ins icon.
Click the icon to start exporting process from the current design.
Before exporting robot description files, please follow the following instructions to make sure the design file is suitable to execute this add-in.
To prevent unexpected modification of the original design, it is better to run this add-in in a copy of the design file.
- Exit parametric mode: right click the root component of the design, choose
Do not capture Design History
- Set the default unit of the design document to
m
- Using
Break Linkto make external component into internal component
- Occurrences refer to the same component are not supported yet, use
Make Independentto independ those occurrences.
-
- Make sure all the components are named with alphanumeric characters, underscore character
_, and hyphe character-. Other languages and characters might cause problems.
- Make sure all the components are named with alphanumeric characters, underscore character
-
- Components need to be joint together with a flat structure in order to export the robot description files properly. Please check the instructions for Fusion360 Assembly.
Click the add-in icon, then chose the robot description format and targeted simulation platform to export.
- Test a closed loop linkages in Gazebo to show the ability of SDFormat to describe a closed-chain mechanism
- Test a UR5e manipulator in Gazebo
- Test Robotiq-2F85 Gripper in Gazebo
We also provides some robot models that assembled manually, and tested the Add-In with these models. This robot library is continuing update, it is welcome to contribute this library.
