译文：Due to the rising labor costs, AGV can effectively reduce costs, improve production efficiency and other advantages, so AGV is more and more popular, more and more production and logistics projects adopted. AGV navigation technology is widely used in the market at present, there are mainly AGV visual navigation and AGV laser navigation two technologies, so how do they work? In fact, both of these methods are realized through SLAM algorithm (synchronous localization and mapping). SLAM refers to the fact that a moving object in an unknown environment calculates its own position according to the information of the sensor while constructing an environmental map or model to solve the localization and mapping problems of robots.
