These wires transmit radio signals via onboard antennae. Wired navigation refers to AGVs that follow thin wires embedded in the facility's floor. These models can perform without risk of track obstruction due to contaminants. Sterile facilities like medical and electronic manufacturing plants can leverage their clean environment by using colored tape-guided AGVs. Particularly dusty facilities might opt for a different type of AGV to overcome the shortcomings of vision-based navigation. These AGVs can struggle in dirty environments where the colored tape can be obscured, and the sensor lens can become dirty. Sensing hardware includes simple vision systems that identify the specially-colored tape. Routes can be easily reconfigured by reapplying the navigation tape. This type shares many similarities with the magnetic tape-guided types. The simple colored tape-guided type is another standard navigation method. Magnetic tape-guided AGVs can still perform due to their resistance to non-ferromagnetic contaminants. Tile manufacturing facilities provide a challenging environment due to dirt and dust. These materials include iron, nickel, cobalt, and associated alloys common to the metals industries. However, these types can struggle in environments where ferromagnetic particles or shavings can be present. Magnetic tape is also useful for dirty environments. This is a cost-effective method for rerouting compared to other methods. Simple induction sensors and magnetic tape are essential navigation tools, which can be low-cost compared to more expensive navigation technologies.Īdditionally, routes can easily be reconfigured by removing the old tape and applying new tape on a different path. First, mag-guided AGV technology is a cost-effective option due to the simplicity of the hardware required. There are a few reasons why this option is so popular. Magnetic guide tape types are the most common AGV. This is a crucial consideration when researching AGVs because they offer their own benefits and shortcomings. The types of AGVs are defined by their sensing mechanism to navigate their environment. In addition, they often handle how AGVs communicate with other systems in the facility such as other machines and warehouse logistic software, for example. These control systems determine AGV behavior, such as load balancing and charging. Examples include fleets consisting of multiple AGVs. We’ll discuss different sensing methods in the Types of AGVs section.ĪGVs feature software packages that allow for machine control, and status updates and fleet management systems are available for even more complex systems. AGVs are fitted with various sensors and hardware to navigate complex facilities. Once that signal is received, they move to another location. They usually have a starting point where they wait for a signal or instruction. How do AGVs Work?ĪGVs often have simple tasks that can be generalized as point-to-point motion. AGVs are often deployed in various logistics applications to help manufacturers transport material efficiently. However, as we will discover later, other types of AGVs offer different navigation methods. Common types of AGVs follow magnetic or colored strips along the facility's floor to navigate. Most AGVs resemble small-to-medium-sized carts, dollies, or forklifts. What are AGVs?ĪGVs, as their names suggest, are unmanned, self-propelled, mobile transporters. This article will cover the basics of AGVs, their applications, comparisons to other mobile robot technologies, and help you determine if they could be suitable for your application. Yet, despite its long history in industrial manufacturing, AGV technology remains a mystery for many of today’s industry leaders. Learn how they’re applied and how they drive positive results across industries.Īutomated guided vehicles (AGVs) have helped manufacturers optimize facility logistics for over 50 years. AGVs transform internal logistics operations for modern manufacturers.
