URDF Validator (catches real robot failures, privacy-first, with xacro support)
New tool flags critical issues in Valkyrie and Fetch robot models that other validators miss.
RoboInfra has launched a URDF Validator designed to catch real-world robot description failures that typically slip past standard syntax checkers. Unlike basic validators that only check XML structure, this tool analyzes URDF semantics—detecting broken kinematic chains, invalid joint references, and leftover xacro artifacts that cause failures in Gazebo simulation, motion planning, or TF tree generation. It has already identified critical bugs in widely-used production models including NASA's Valkyrie humanoid robot and Fetch Robotics' mobile manipulator.
The validator operates as a privacy-first web API that processes URDF and .xacro files without storing any user data. It provides human-readable error explanations with specific upgrade guidance, helping robotics engineers transition from xacro macros to standard URDF. The stateless architecture ensures no training occurs on proprietary robot designs, addressing industry concerns about IP protection while delivering immediate validation through a simple curl command or web interface.
- Catches semantic errors in production robots like Valkyrie and Fetch that cause simulation failures
- Privacy-first stateless API with no data storage or training on user files
- Supports .xacro files with guided upgrade hints and human-readable error explanations
Why It Matters
Prevents costly simulation failures by catching robot description bugs before deployment, saving engineering time.
