SimpleRobotJSON

SimpleRobotJSON is a Fusion 360 Python script that generate a JSON description of a simple robot from joints in the active Fusion 360 document. It is designed to be dropped into Fusion 360's Scripts folder and run from the Scripts and Add-Ins dialog.

The description can be used with unrobot library.

Features

• Create a compact JSON robot description
• Create simple joint relationships between each component
• Intended for small kinematic prototypes and learning Fusion 360 API basics

Requirements

• Autodesk Fusion 360 (latest or recent build)
• Fusion 360 Python API (installed as part of Fusion)

Installation

1. Copy the repository folder (SimpleRobotJSON) to:

   1. MacOS: ~/Library/Application Support/Autodesk/Autodesk Fusion 360/API/Scripts/
   2. Windows: C:\Users\<YourUsername>\AppData\Local\Autodesk\Autodesk Fusion 360\API\Scripts\

2. Open Fusion 360 → Scripts and Add-Ins → My Scripts, select SimpleRobotJSON and Run.

Usage

• Create your robot using Assembly, add constraints, and set this position in "sleep" mode.
• The base component of the robot (the root) need to be called "base_link".
• Run the script from Fusion 360. The script a description from components and joints in the active design.
• Use the generated json with unrobot library.
