mjpl 0.0.1

MuJoCo motion planning library.

mjpl

MuJoCo motion planning library.

[!Note] This project is under active development. APIs may change, and features are still a work in progress.

Features:

• Joint-space planning via bi-directional RRT, with support for constraints
• Cartesian-space planning
• Interfaces for constraints, inverse kinematics, and trajectory generation

Limitations:

• This library is designed for manipulator models that are composed of hinge/slide joints, and will not work with models that have ball/free joints.

Installation

pip install mjpl

Development

For local development, clone the repository and install the developer dependencies:

pip install -e ".[dev]"

This project uses Ruff for linting and formatting. Unit tests are written via the unittest framework.

To run the linter, formatter, and tests locally:

# Check for linter errors
ruff check .
# Apply lint fixes
ruff check --fix .

# Check for format errors
ruff format --diff .
# Apply format fixes
ruff format .

# Run unit tests
python3 -m unittest -v

Pre-commit hooks are also available which run the linter, formatter, and unit tests. To trigger the hooks automatically on commit, install the pre-commit hooks:

pre-commit install

To trigger the hooks manually:

pre-commit run --all-files

To bypass installed pre-commit hooks on commit:

git commit --no-verify -m "your message"
