.sdf → .urdf
SDF to URDF
Convert a robot description from SDF to URDF in the browser. Nothing is installed and nothing is queued: the file is read, written in the other format, and handed back with a list of anything that could not be carried across.

Look at the file first
What this conversion costs
Nothing structural. Every bundled sample — a six-axis arm, a gripper, a generic quadruped and the Unitree A1 at 23 links — came through this direction with its links, joints, geometry and inertia intact. Your model may still hit something these do not cover, and if it does the converted file will say so at the top.
Only the robot comes across
The world around it — ground, lights, other models — has no equivalent in a URDF and is left behind.
One model at a time
An SDF holding several models cannot become one URDF. We take the first and tell you what was skipped.
The two formats
- SDF .sdf
- Gazebo's format, which describes a whole world rather than a single robot.
- URDF .urdf
- the ROS description of a robot: links, joints, geometry and inertia, one rigid tree.
Converting is rarely the whole job. Once you have the URDF, the viewer shows what actually came across — collision geometry against visual, joint limits, where the mass sits — and the physics lab answers the question a file cannot: whether the robot stands up when gravity is switched on.
