I tested URDF format conversion on NASA Valkyrie, UR5, and Franka Panda results and a free tool
Convert URDFs to Gazebo SDF and MuJoCo MJCF with a 14-day free trial, no credit card needed.
RoboInfra has released a free URDF conversion and validation tool aimed at robotics developers who need to bridge simulation formats. The tool supports models from major robots including NASA's Valkyrie humanoid, Universal Robots' UR5, and Franka Emika's Panda. It provides a simple REST API to validate URDF files (9 checks covering structure, links, joints, and collision geometry) and convert them to either Gazebo SDF or MuJoCo MJCF formats—two of the most popular simulation environments in the ROS ecosystem.
The tool is accessible via multiple interfaces: direct API calls (POST endpoints for validation and conversion), a Python SDK (`pip install roboinfra-sdk`), and a GitHub Action (`roboinfra/validate-urdf-action@v1`) for CI/CD pipelines. The 14-day Pro trial doesn't require a credit card, lowering the barrier for testing. With no local ROS installation needed, developers can validate and convert URDFs instantly in the cloud. This fills a common pain point where teams need to share robot models across Gazebo, MuJoCo, and other simulators without manual format adjustments.
- Supports 5 popular robots including NASA Valkyrie, UR5, and Franka Panda for URDF validation and conversion.
- Converts URDF to Gazebo SDF and MuJoCo MJCF via REST API; also offers Python SDK and GitHub Action.
- 14-day free Pro trial with no credit card required; instant 9-check validation with xacro support.
Why It Matters
Streamlines cross-simulator robot model sharing, saving developers hours of manual format conversion.
