![]() With the use of magnetic tape, AGV forklifts are equipped with magnetic sensors to follow a defined track that is made by magnetic tape that has been placed on the floor of the facility. The system does not require wire or tape on the floor or location devices beneath the surface of the floor. Manufacturers rapidly install reflectors, simulate AGV paths, and define AGV routes with little effort. The reason for the popularity of a laser guided navigation system is how easy it is to install. The calculations made by the navigation system are incredibly accurate. Positioning corrections are made 30 to 40 times per second to keep the forklift in the correct trajectory. Three array feedbacks are necessary for position calculations and use a highly complex and intricate algorithmic formula. The reflectors send the laser array signals used by the navigation device. ![]() The targets for the laser are reflector tape or cylinders around 20 inches high that are positioned on columns, walls, or poles in a facility. The laser sends rotating arrays in a 360o pattern. The forklift has a navigation laser located on top of a pole on top of the forklift that interacts with targets strategically placed in the work area. AGV Forklift Navigation Systems Laser Guided (LGV) NavigationĪ LGV navigation system uses laser positioning and is the most popular system. In the case of forklifts and their functions, navigation systems are necessary and keep the forklift within a set of safety parameters. The guided lights or strips for AGV forklifts are not common to all AGV vehicles since technological advancements are rapidly improving and changing. Though it may seem that they are moving independently, for every AGV forklift, there is a guiding navigation system that determines their path from which they are unable to vary. Chapter Two – AGV Forklift Navigation Systems TypesĪs robotic devices, AGV forklifts move freely and unhampered from location to location in a series of programmed maneuvers. The key to the success of an AGV forklift is choosing the navigation system to fit the application’s needs. There are a variety of guidance systems used on AGV forklifts, including laser guided vehicle (LGV) systems, magnetic tape, natural navigation, and magnetic spots. ![]() They include counterbalance and outrigger designs with load capacities as high as 10,000 lbs or higher. They are part of a complex and complicated technical system that is composed of computer programming, robotics, and peripherals.ĪGV forklifts are capable of handling a variety of load sizes for pickup and drop off from the floor and elevations such as conveyor systems and storage racks. An automatic guided vehicle (AGV) forklift is a computer controlled mechanism that performs a series of functions without the interference or guidance of a human. An AGV forklift is a driverless self-operating robotic device that has the ability to carry, lift, retrieve, and place loads for easy transfer from one location to another. ![]()
