As early as more than 40 years ago,automated guided vehicles that automatically transport materials were born in factories.Mainly using magnetic navigation,is the first generation of navigation technology.It can be said that this is the initial stage of industrial logistics.

With the development and transformation of navigation and positioning technology,the second-generation navigation technology marked by QR code navigation was born.Amazon KIVA logistics robots used QR code navigation for the first time,which promoted the use of intelligent warehouse robots in a number of domestic e-commerce companies.QR code navigation.

Since then,there have been lidar navigation and visual navigation.From the general cognition of the industry,the first two can be divided into AGVs,and the latter two,also known as natural navigation mobile robots,can be divided into AMRs.

Under the control of the navigation algorithm,AMR realizes independent movement and accurate obstacle avoidance through built-in maps,external lidars and visual cameras.Compared with AGV,the main feature of AMR is that there is no fixed navigation path,and dynamic planning is more flexible.

早在40多年前，自动搬运材料的自动导航车就诞生在工厂里。主要采用磁导航，是第一代导航技术。可以说，这是工业物流的初始阶段。

随着导航和定位技术的发展和变革，以二维码导航为标志的第二代导航技术诞生，亚马逊KIVA物流机器人首次使用二维码导航，推动了一批国内电子商务企业的智能仓库机器人使用二维码导航。

此后，出现了激光雷达导航和视觉导航。从行业普遍认知来看，前两者可分为AGV，后两者又称自然导航移动机器人，可分为AMR。

AMR在导航算法的控制下，通过内置地图、外置激光雷达和视觉摄像头实现独立移动和准确避障。与AGV相比，AMR的主要特点是没有固定的导航路径，动态规划更加灵活。
