AGV Forklift Guidance System
AGV forklift automatic guidance systems include magnetic navigation, laser navigation, electromagnetic navigation, optical navigation, inertial navigation, visual navigation, etc. Currently, laser navigation, electromagnetic navigation and visual navigation are the mainstream.
Install a laser reflecting plate with accurate position around the AGV driving path. The AGV emits a laser beam and collects the laser beam reflected by the reflecting plate to determine its current position and direction, and realizes the AGV through continuous triangular geometric operations. navigation. The laser navigation driving path can be flexible and can be adapted to a variety of on-site environments, but the shortcomings are the high cost and the harsh requirements on the environment.
2) Electromagnetic navigation is one of the more traditional navigation methods, which is still used at present. It is to bury a metal wire on the AGV's driving path, and load the guide frequency on the metal wire, and realize the AGV navigation by identifying the guide frequency. The advantage is that the cost is low and it is easy to control, but the driving route is difficult to change and expand, which has great limitations on complex routes.
Visual navigation, also known as VSLAM, that is, simultaneous positioning and map construction refers to a system that generates positioning and scene map information about its own position and posture by collecting and calculating various sensor data. It can obtain massive and redundant texture information from the environment, and has superb scene recognition ability. The advantages are lower cost, environmental adaptability and strong flexibility. Visual navigation is a cutting-edge technology and has a high technical threshold.
The future robot vision navigation unmanned driving module integrates a visual positioning system, servo control system, multiple perception system and safety protection system, with functions such as self-positioning, precise control, environment adaptation and safe obstacle avoidance. The visual navigation unmanned driving module has the characteristics of high cost performance, high flexibility, high efficiency, safety and stability. With the future robot central control system and scheduling system, it greatly improves the application breadth and depth of unmanned industrial vehicles in complex scenarios.
