How does map resolution affect robot navigation performance?

Asked on Oct 24, 2025

Answer

Map resolution significantly impacts robot navigation performance by influencing the accuracy and efficiency of path planning and obstacle avoidance. Higher resolution maps provide more detailed environmental data, allowing for precise navigation but at the cost of increased computational load. Conversely, lower resolution maps reduce computational demands but may lead to less accurate navigation due to insufficient detail.

Example Concept: In robot navigation, map resolution refers to the granularity of the environmental representation. High-resolution maps capture finer details, which are crucial for tasks requiring precision, such as navigating through cluttered environments. However, they require more processing power and memory. Low-resolution maps simplify the environment, which can speed up computation and is useful in less complex areas, but may miss smaller obstacles, potentially leading to navigation errors.

Additional Comment:

High-resolution maps are beneficial for SLAM (Simultaneous Localization and Mapping) as they improve localization accuracy.
Consider the trade-off between map detail and processing capability when designing navigation systems.
Adaptive resolution techniques can dynamically adjust map detail based on the robot's current task or environment.
