OpenLegged/URDF-Studio

URDF-Studio is a web-based visual URDF robot modeler with 3D workspace, structured skeleton/detail/hardware workflows, motor library integration, MuJoCo export, and AI assistance.

What it solves

URDF Studio provides a professional, browser-based workstation for designing and visualizing robots. It eliminates the need to manually edit raw XML files when defining robot topology, visual and collision geometry, and hardware parameters.

How it works

Built with React and Three.js, the platform offers a unified editor for kinematic trees and hardware configuration. It uses a worker-assisted pipeline for importing and exporting various robot description formats. It also integrates an AI assistant via the OpenAI SDK to help users generate robot structures from natural language, perform automated inspections, and receive optimization suggestions.

Who it’s for

Robot designers and engineers who need a rapid, visual way to author robot descriptions and manage multi-robot assemblies without relying solely on text-based XML editing.

Highlights

  • Multi-format Support: Export to URDF, MJCF, USD, SDF, Xacro, and more.
  • AI-Powered Authoring: Natural language robot generation and automated inspection reports (PDF/CSV).
  • Visual Editing: Integrated tools for topology editing, collision optimization, and hardware parameter configuration.
  • Multi-robot Assembly: Ability to assemble multiple robots into a single workspace using bridge joints.
  • Reusable Component: Includes a publishable @urdf-studio/react-robot-canvas package for external 3D robot visualization.
