A superior alternative to `robot_localization` for mobile robot sensor fusion, offering a 22-state UKF that directly fuses IMU, wheel encoders, and GPS in ECEF, with automatic noise covariance adaptation and outlier gating.
FusionCore directly addresses critical performance and usability issues within the ROS 2 robotics ecosystem, specifically challenging the widely adopted `robot_localization` package. The author's motivation stems from common developer pain points: complexity of coordinate transformations (UTM zones), manual tuning (YAML covariance), and reliability issues. FusionCore's technical advantages—direct ECEF fusion, automatic noise covariance adaptation, and outlier gating—demonstrate a sophisticated approach to state estimation. The benchmark results, outperforming `robot_localization` EKF in 5 out of 6 real-world scenarios, provide compelling evidence of its superiority. This project highlights the market demand for robust, high-precision localization solutions in robotics, where accuracy and reliability are paramount. It signals an opportunity for specialized, performance-optimized components to displace established, but less efficient, open-source standards.
I built sensor fusion for a mobile robot and reached for robot_localization like everyone does. After spending too long fighting navsat_transform, UTM zone boundaries, and YAML covariance tuning, I wrote my own.FusionCore is a 22 state UKF that fuses IMU, wheel encoders, and GPS in ECEF directly (no coordinate projection, no extra node). It estimates IMU bias, adapts its noise covariance automatically from the innovation sequence, and gates outliers with a chi squared test on every sensor.I benchmarked it against robot_localization EKF on 6 sequences from the NCLT public dataset (University of Michigan, real robot, real GPS, RTK ground truth). It wins 5 of 6. On the 6th sequence (fall, degraded GPS over a long period) it loses badly. RL UKF diverged to NaN on all six.Configs, methodology, and full reproduce instructions are in the benchmarks/ folder.

> it wins 5 or 6Yeah but the 5 that it wins on a very marginal and the 1 that it loses on definitely loses. I'd also say it loses the top middle one thanks to that spike on the left.lf it's easier to use I'd say the performance is close enough though!
