Free Engineering Tools — robotics, simulation, and compliance utilities
Browser-based tools for robotics and hardware engineers: URDF validation and conversion, CAD-to-simulation, SBOM and EU CRA compliance. Files never leave your browser.
Convert Xacro → URDF Expand properties, macros, conditionals, and multi-file includes in the browser — no ROS install. Validate URDF Validator Structure, kinematic tree, inertia sanity, and joint limits checked against parser-divergence pitfalls. Convert URDF → MJCF MuJoCo XML with correct half-extents, radians, and nested body tree. Verified against MuJoCo 3.10. Convert SDF → URDF Gazebo model-frame poses resolved into correct relative joint origins with full transform composition. CAD STEP → URDF CAD in, URDF + STL meshes out — mass, COM, and full inertia tensor computed from the geometry. Comply SBOM Generator Lockfile in, CycloneDX 1.6 out — full transitive dependency tree with package URLs. Comply CRA Readiness Checker Cyber Resilience Act scoping memo, classification, and obligations checklist — every branch cited.
Nothing to install — check your browser instead
No Python, no C++, no ROS, no downloads: every tool runs inside your browser using JavaScript and WebAssembly (the CAD kernel is C++ — compiled to WASM and delivered like any web page). Any modern browser from roughly 2021 onward works. Here's what your browser says right now:
