robot_descriptions 0.4.0

Import open source robot description as Python modules.

Robot descriptions in Python

Import open source robot descriptions as Python modules. The wrapper automatically downloads and cache files at first import. Most Awesome Robot Descriptions are available.

All descriptions load successfully in PyBullet.

Installation

pip install robot_descriptions

Usage

Import the robot description you are interested in directly as a submodule of robot_descriptions:

from robot_descriptions import my_robot_description

The import will automatically download the robot description if you don't have it already, and cache it to a local directory. The submodule then provides the following paths:

URDF_PATH / MJCF_PATH

Path to the main URDF/MJCF file of the robot description.

PACKAGE_PATH

Path to the root of the robot description.

REPOSITORY_PATH

Path to the working directory of the git repository hosting the robot description.

Some robot descriptions include additional fields. For instance, the iiwa_description exports URDF_PATH_POLYTOPE_COLLISION with more detailed collision meshes.

Loaders

The library also provides a one-stop shop load_robot_description function for each of the following robotics software:

Software	Loader
Pinocchio	robot_descriptions.loaders.pinocchio
PyBullet	robot_descriptions.loaders.pybullet

The function loads a robot description from its name, and returns an instance directly usable in the target software. For example:

from robot_descriptions.loaders.pinocchio import load_robot_description

robot = load_robot_description("upkie_description")

Examples

Load a robot description:

• MuJoCo
• Pinocchio
• PyBullet

Visualize a robot description:

• MeshCat
• MuJoCo
• PyBullet
• yourdfpy

Command line tool

The command line tool can be used to visualize any of the robot descriptions below. For example:
