Choosing the right navigation technology is one of the most critical decisions when deploying an AGV fleet. In this guide, we compare the two most common approaches: **LiDAR natural feature navigation** and **QR code / marker-based navigation**. ### QR Code Navigation QR code (or magnetic marker) navigation uses visual or optical sensors to read markers placed on the floor along predefined paths. The robot follows a fixed route, repositioning itself whenever it reads a code. #### Advantages - High positioning accuracy (±10mm) in controlled environments - Mature technology with proven reliability - Lower robot hardware cost for basic implementations #### Limitations - Requires floor marker installation and periodic replacement - Routes are fixed; changes require re-marking the floor - Markers can be damaged by forklift traffic, dirt, or spills - Poor performance in dynamic or cluttered environments ### LiDAR Natural Feature Navigation LiDAR SLAM (Simultaneous Localization and Mapping) navigation builds a map of the existing environment using laser scanners. The robot localizes itself by matching its real-time sensor readings against the saved map of walls, racks, pillars, and fixed objects. #### Advantages - No floor markers or infrastructure changes required - Routes can be updated in software — no physical reconfiguration - Adapts to environmental changes with dynamic mapping updates - Better obstacle avoidance and dynamic path planning #### Limitations - Slightly higher initial hardware cost - Requires sufficiently distinctive environmental features for reliable localization - Performance degrades in highly open or featureless spaces ### Which Should You Choose?
