A modular C++ and ROS 2 framework for building configurable LiDAR odometry and SLAM pipelines.
MOLA is a modular optimization framework for localization and mapping (SLAM) designed for robotics applications. It provides configurable pipelines for LiDAR odometry, sensor fusion, and map creation, solving the problem of building customizable, high-performance navigation systems. The framework enables researchers and developers to assemble and experiment with different SLAM components without rewriting core infrastructure.
Robotics researchers, autonomous vehicle developers, and engineers working on SLAM, localization, and sensor fusion systems who need a flexible, high-performance framework. It's particularly valuable for those using LiDAR and inertial sensors in ROS 2 environments.
Developers choose MOLA for its modular architecture that allows easy customization of SLAM pipelines, its native ROS 2 integration while maintaining standalone C++ usability, and its proven performance in real-world LiDAR odometry scenarios demonstrated through published research and benchmarks.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Enables plug-and-play assembly of ICP and SLAM components, allowing researchers to experiment with different configurations without modifying core code, as highlighted in the features section.
Fully compatible with multiple ROS 2 distributions like Humble and Rolling while supporting pure C++ usage, offering deployment versatility for both robotic systems and offline processing.
Demonstrated accurate odometry and mapping in demos with datasets like KITTI and Oxford, backed by peer-reviewed research publications cited in the README.
Supports flexible integration of multiple sensor inputs for localization, facilitating custom setups beyond standard LiDAR and IMU, as indicated in the sensor fusion feature.
Released under the GNU GPL v3 license, which imposes copyleft requirements and may restrict commercial use without alternative licensing agreements, as noted in the license section.
The modular architecture requires detailed YAML configuration and pipeline assembly, which can be daunting for users seeking quick setup, as implied by the emphasis on modularity and external documentation.
Primarily focused on LiDAR-based methods like LO and LIO, with less emphasis on pure visual or visual-inertial odometry compared to other frameworks, despite some video input modules.
