LinkForge: Visual Designer for the Programmable Robot Description Engine

In robotics, creativity starts in your head but getting that idea into a simulator usually means hours of writing fragile XML, fixing joint limits, and fighting impossible inertia matrices.

LinkForge removes that friction. Built on top of a rigorous, mathematically validated Intermediate Representation (IR) engine, this extension transforms Blender into a professional robotics IDE. Model your robot naturally, validate its physical integrity in real-time, and guarantee the output is strictly compliant, simulation-ready code.

From idea → validated topology → ready for simulation. All inside Blender.

Key Features

• Validated Assembly (The Safety Net): Build complex robot topologies with absolute confidence. The built-in physical linter catches "exploding robot" errors like disconnected links, naming collisions, and unphysical inertia tensors before you export to Gazebo or Isaac Sim.
• High-Performance Physics: Stop guessing mass properties. LinkForge uses scientifically accurate mathematical models (Mirtich/Sylvester algorithms) to calculate exact inertia tensors and Center of Mass offsets for both primitive shapes and complex arbitrary meshes.
• Bidirectional Round-Trip Fidelity: Seamlessly import existing URDF/XACRO files. The Import → Edit → Export cycle preserves all original data with absolute precision, including sensor origins, transmission interfaces, and custom user properties.
• Complete Sensor Suite: Integrated support for Camera, Depth Camera, LiDAR, IMU, GPS, Force/Torque, and Contact sensors with highly configurable noise models.
• ROS 2 Control Integration: Visually configure hardware interfaces, joint limits, and actuation vectors via a centralized dashboard to auto-generate compliant ros2_control configurations.
• Advanced XACRO Support: Intelligently extract repeated geometries into macros and shared materials, producing clean, maintainable, and modular XML.
