What it does

URDF robot description authoring and validation. Use when creating, editing, inspecting, validating, or debugging `.urdf` files, robot links, joints, limits, inertials, visual/collision geometry, mesh references, frame conventions, or robot-description artifacts. Use the SRDF skill for MoveIt2 semantic groups and IK/path-planning semantics; use the CAD skill for STEP/STL/3MF/DXF/GLB outputs. Open and visually review existing URDF files in CAD Viewer.

URDF

Provenance: maintained in earthtojake/text-to-cad. Use the installed local skill files as the runtime source of truth; the repository link is only for provenance and release review.

Use this skill for URDF robot-description outputs. Treat URDF work as constrained kinematic modeling, not just XML writing. The main correctness risks are frame placement, joint-axis semantics, unit consistency, mesh scale, and inertial data.

Setup

Run cadgen through the cadgen command its installation writes, so this skill's commands share one installation, and its engine server, with the CAD app's:

  • cadgen below means cadgen +0.8.4 (~/.local/bin/cadgen +0.8.4 where ~/.local/bin is not on your PATH)
  • python below means cadgen +0.8.4 run

For first-time setup or an update, a missing cadgen command, a release it says is not installed, an engine that is not running, or an installation or kernel load error, read Setup and troubleshooting.
