About this paper
Kirill Muravyev, Konstantin Yakovlev
NavTopo, a complete autonomous navigation pipeline for mobile robots, utilizes topological maps to address the limitations of metric SLAM. The system demonstrates significantly reduced memory consumption (57 MB) and faster path planning (6 ms) compared to a metric SLAM baseline, achieving these gains in a simulated large indoor environment.
Key insights
- Topological maps offer substantial advantages in terms of memory consumption and path planning speed over dense metric maps, making them suitable for large-scale environments.
- Combining deep learning-based place recognition with 2D scan matching provides an efficient and accurate localization mechanism without requiring the storage of raw 3D point clouds.
- A hierarchical planning approach, leveraging the sparsity of topological graphs for global routes and local metric grids for immediate movement, balances computational efficiency with navigational precision.
