Adaptive resolution grids

Definition

Adaptive resolution grids are a mapping technique used in robotics that dynamically adjusts the resolution of the grid based on the complexity of the environment. This means that areas with more obstacles or important features are represented with a finer grid, while simpler areas use a coarser grid. This approach allows for efficient path planning and resource management, as it reduces the computational burden while maintaining accuracy where it is most needed.
