An AGV (Automated Guided Vehicle) is an industrial vehicle used in warehouse or manufacturing environments to transport goods based on pre-programmed instructions. AGVs typically require the installation of navigation guides such as magnets or wires on or beneath the warehouse floor, which may involve significant facility modifications. If there is a need to change the AGV operating pattern, it often requires facility modifications to alter the navigation guides. AGVs can be seen as having limited flexibility to adapt to rapidly changing environments or work processes. 

An AMR (Autonomous Mobile Robot) is a vehicle that uses onboard sensors and processors to autonomously navigate and move materials without the need for physical guides or markers. In simple terms, it learns the environment and remembers its position, similar to how a robot vacuum cleaner operates. It dynamically plans paths from one location or waypoint to another within the environment.

AMRs utilize technologies such as LiDAR sensors and SLAM (Simultaneous Localization and Mapping) to determine optimal routes between waypoints. This allows them to adapt to changes in the workspace configuration, even if it changes overnight. They can automatically detect and navigate around obstacles and blocked paths, finding the most efficient route to the next waypoint.
