## What it is
A curated awesome-list of robot description models in URDF, Xacro, and MJCF formats, organized by robot type (arms, humanoids, quadrupeds, drones, etc.). Each entry links to the model source with license and fidelity details.

## Use cases
- find a URDF model of a robot arm for simulation
- download humanoid robot descriptions for MuJoCo
- locate quadruped MJCF models for reinforcement learning
- compare robot model licenses and fidelity before using one
- find robot models for ROS or Gazebo projects

## When to choose
- you need ready-made robot description files for simulators like MuJoCo, Gazebo, or PyBullet
- you want a vetted index of models with license and fidelity info
- you are benchmarking or training policies on standard robots

## When to avoid
- you need actual robot control software or drivers
- you need a single maintained model rather than a directory of links
- you need CAD files or hardware documentation

## Facets
- artifact type: dataset
- maturity: active
- function: simulation, robotics
- domain: robotics, simulation, awesome-lists
- platform: cross-platform
- tags: urdf, mjcf, xacro, robot-descriptions, curated-list, humanoid, quadruped
