A new blender extention for making Gazebo static models
New Blender add-on exports 3D models directly to Gazebo's SDF format with single-click workflow.
Developer yjphhw has released the SDF Static Model Exporter, a new open-source Blender add-on designed to bridge the gap between advanced 3D content creation and physics-based robotics simulation. The tool provides a direct pipeline from Blender's comprehensive modeling suite to Gazebo's SDF (Simulation Description Format), the official model specification for the popular simulator. This addresses a key pain point where Gazebo's native modeling tools are limited, allowing creators to build visually rich, static environments in Blender and export them for use in Gazebo with a single click, significantly enriching simulation scenarios.
The extension, licensed under MIT, is a lightweight (~50KB) tool that automatically handles mesh optimization for physics simulation while preserving object transformations and hierarchy. Currently focused on static models, its roadmap includes future support for textures and custom materials. An accompanying 10-minute video tutorial on Bilibili demonstrates the workflow. For robotics engineers and simulation developers, this tool eliminates manual conversion steps, enabling faster iteration on simulation environments and more detailed virtual testing grounds for autonomous systems and robotic algorithms.
