Evaluation of LiDAR SLAM performance on the Sequential trajectories simulation (Robot 2) dataset, measuring Trajectory Position RMSE.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | LiDAR SLAM |
| Dataset (including any stated split) | Sequential trajectories simulation (Robot 2) |
| Metric | Trajectory Position RMSE (m) |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 3 of 3 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Trajectory Position RMSE (m)](<https://www.sota2.com/research/sota/lidar-slam-on-sequential-trajectories-simulation-robot-2.md?metric=Trajectory%20Position%20RMSE%20(m)>): Lower is better; unit: SCALAR.
