An automatic guided vehicle (AGV), is an unmanned, computer-controlled mobile transport unit used for material handling and transportation in a wide range of industries. Also known as a self guided vehicle or self propelled vehicle, an AGV is a vehicle that is powered by a battery or an electric motor and is able to perform tasks without human supervision or operation.
AGV manufacturers program AGVs to drive to specific points and perform designated functions such as load transferring, small parts assembling, pallet loading and transportation, towing or lifting products and tooling change out, without the aid of a human driver. Autonomous guided vehicles are becoming increasingly popular worldwide in applications that call for repetitive actions over a distance or for transporting extremely heavy loads and are commonly used as alternative for fork lifts, conventional conveyor systems and manually powered push-pull carts. AGV systems provide great benefits in terms of increasing efficiency and reducing human error and varieties of AGVs such as material handling robots, automatic guided carts and transfer cars are used in place of manual labor for a number of applications. Automated guided vehicles are also commonly used as automatic guided military vehicles and armored vehicles in defense industries, or for clean room applications in which human presence may be undesirable. Industries such as aerospace, automotive assembly, general manufacturing, mail and newspaper, food and beverage processing and parts assembly all use types of guided vehicles to help improve work flow.
Many industrial manufacturing facilities use automated guided carts as an alternative to conventional conveyor systems. These vehicles, and larger AGVs, can transport cumbersome loads with relative ease and are able to move multi-ton equipment or materials such as aircraft engines or large metal coils, across the plant floor. Different models, which include forked AGVs, tuggers, towing vehicles and transfer cars, have wide ranging load capacities and design characteristics, such as material handling robot components. They come in varying sizes and shapes, according to their specific uses, load requirements and industry. Guidance systems used to direct automatic guided vehicles vary according to the complexity of the application and the required performance of the AGV. Some methods of guiding AGVs include the use of lasers. The laser guided vehicle has advanced navigation capabilities and is able to navigate around obstacles on a programmed path and avoid collisions independently using laser beam sensors. However, fixed path systems or free range systems are the most common options. Fixed path systems use embedded wire, magnetic tape or colored paint as a guide for simple vehicle routes. The AGV uses sensors and frequencies to follow the path of the wire or tape. These are reliable and fairly simple systems to install, however they have the drawback of inflexibility. Free range systems are far more common today and these use computer-based programming to control the vehicles with onboard microprocessors and a supervisory control system. The addition of computer programming helps with various tasks, such as tracking and tracing modules and generating and/or distributing transport orders.
Manufacturers of automotive guided vehicles program the AGVs for many different and useful maneuvers, such as spinning and side-traveling, which allow for more effective production rates. Some systems, especially those with a number of guided vehicles may require the assistance of a system operator to ensure that malfunctions and collisions do not occur. However, most of the simpler systems are capable of operating independently and will only periodically require adjusting or correcting. AGVs can do hard physical work without wear or exhaustion, eliminating human labor which would otherwise be costly and potentially hazardous. Loads that AGVs carry are far heavier than any single human could manage, which makes transporting heavy objects quicker and simpler than it would be with manual assistance. Corporations that use automatic guided carts and vehicles, such as factories, warehouses, hospitals and other large facilities, benefit from the power, stability and remote operating capabilities of automated vehicles. They are flexible and can be adapted to many different needs. Using automated guided vehicles often results in reduced labor costs to the manufactured as well as increased income due the improved efficiency of the output process. AGVs help give companies a competitive edge because they increase productivity and time efficiency. Using AGVs may also reduce wear to products and improve the safety on the factory floor as fewer machines and workers are prone to damage due to human negligence.
Purchasing AGVs often involves making large initial monetary investments, as most automated guided vehicles are manufactured with a number of costly materials and guidance systems. For highly specialized applications, the numerous customizations required by an AGV system could further add to the costs of fabrication and installation. Free range systems using complex computer software require a high amount of initial design, engineering and input which costs a manufacturer both time and money. However, the numerous benefits to implementing AGV systems, especially into larger scale manufacturing facilities and warehouses are numerous and companies and manufacturers often see a quick return on investment. As output production is increased and time and labor costs reduced, the efficiency of using AGVs is well worth the investment. AGV use is continuing to become more popular and manufacturers are finding ways to lower the costs of producing guided vehicles. They are designing smaller, more affordable models for applications and basic options are now more widely available. Research is on-going, and new developments on software and movement techniques are frequently being made.

The benefits of AGV systems and their adoption by major industries have encouraged investments; soon guided vehicles will be a norm.
Arguments are ensuing among experts on the superiority of forklifts vs. automatic guided vehicles (AGVs) in the materials handling industry. Some experts see AGVs as a threat to the conventional forklift. Whereas many view AGVs as inevitable change that industries have to adopt to be competitive at the global level, especially after the recent fall in the manufacturing industry of the US due to high labor cost. Many experts see AGVs as an effective measure to cut labor cost.
It is quite easy to predict that in the near future automated guided vehicles will be used extensively across all industries; however, now, the question is: are they effective enough in their present form to invest in them?
In this blog, we will discuss the advantages of forklifts and self-guided vehicles, so you can decide which one can better serve your business needs.
Advantages of AGVs
Advantages of Forklifts
We hope, the compiled advantages of both the vehicles will help you to make your decision, if you, like many others, are stuck in the dilemma of embracing the change or invest in forklift.
Recently, Inc. magazine, a publication for entrepreneurs and business owners, published a list of eight best industries for starting a business, and among all the industries, automated guided vehicles (AGVs) industry ranked first. "As companies continue to mechanize their operations, they're investing big time in heavy-duty machinery. So the market for so-called automated-guided vehicles such as forklifts, loaders, and towing vehicles is getting hotter by the day. If you can muster the major startup costs to get going, AGVs can help you clean up," said the magazine.
Many may contest this ranking; however, there are markers pointing at the surge in the investment in this industry. The most visible among them is Amazon's $775 million acquisition of Kiva Solutions in 2012. Kiva Solutions, an automated material handling company, makes small self-propelled vehicles, which according to many are too small to call AGVs. The acquisition shook the business world, since it was famous Jeff Bezos-an e-commerce baron-who invested money in the business. Given his sharp business sense that led the rise of Amazon as the world's largest e-commerce site, not many can challenge his investment decision. Investors are taking note of the rise of the AGV industry, so are many change-resistant industries, including auto and beverage industry, which have started adopting automation equipment and systems into their processes. This change in mindset has come because the technology has proved its application and is proving to be a great resource when it comes to lowering operating costs.
Present-day AGV systems present numerous advantages:
Various types of AGVs
Different models of guided vehicles that are specialized in towing; with capacities that can go up to 50,000 lb. Towing AGVs can tow single or multiple trailers, depending upon the model, and can be configured for manual use and automatic loading.
Unit-load carrier vehicles have a rugged steel frame construction, which is specially designed to function in heavy industrial environments. Depending on the model, vehicles have varied capacity, steering, dimensional, and load transfer characteristics.
Automatic carts have flexible usages; they have both towing and carrying capacity. They are also half the cost of a conventional AGV. They look more like a rectangular platform, unlike any other automatic guided vehicles.
Automated fork vehicle
It looks like a standard forklift, only it is fully automated, and its capacities range from 1,200 to 4,000 lbs. However, carrying capacity can vary based on the model.
These are high-tech AGVs, with applications in healthcare industry, incorporating virtual-path navigation technology. They can be used to carry food, linen, trash, supply, surgical kit type carts, among others.
Given the emergence of these automated vehicles, it can be said we are on the cusp of a revolution that will change the shape of many industries forever.
We are seeing the rise of robotic technology which is increasingly taking control of both our harmless daily lives and warzones. Self-driving cars by Tesla and Google are becoming ever-present, so are the unmanned aerial vehicles and submarines that are armed with missiles.
However, it is less-known automated guided vehicles or automatic guided vehicles (AGVs) that are changing the landscape of robotic technology and business, with their range of applications. AGVs are not only giving sustainability but also raking in significant profits for a large number of businesses that have adopted them over the time.
AGV Systems are the real embodiment of future robotic technology that we are eager to embrace. The revolution has already started, we have just been a bit ignorant about it.
What are they?
The vehicle is a forklift-size carts that can navigate, without any assistance, in ports, logistic centers, processing plants, factories, etc. Their movement is regulated and controlled by preloaded software, with the assistance from magnetic strips, lasers, and cameras installed on them. They are basically used for moving large loads, and depending on the role coded in their software, they can do range of work, from elevating, pushing, and towing to clamp-and-lift.
AGVs made their first significant mark in the logistics industry. However, they are now being used in a range of fields, including automotive, general manufacturing, aerospace, packaging, mail and newspaper, food processing, metals, and plastics.
Self-Guided Vehicles may look futuristic; however, they have their roots in the 1950s. Arthur Barrett, an electrical engineer, who later founded Barrett Electronics, invented a vehicle that slid on a floor with assistance from a wire, rather than a track, a standard in those days. He marketed it in 1954, calling it Guide-O-Matic driverless vehicle.
Even today, some guided vehicles use Barrett's model; however, for navigation, magnets or magnetic tape is used instead of a wire.
We are seeing newer technologies advances, which are allowing so-called self-propelled vehicles to triangulate their positions with respect to the surrounding, making use of laser, transmitters and sensors. The newest AGVs use a camera-based navigation, which gives the vehicle high potential in mix environments, unlike its predecessors. The vehicle practically takes photographs of the surroundings, saves them, and uses that information to drives itself along the path. It still uses lasers, as a secondary support. A light curtain surrounds these newer laser guided vehicles during operation, and a sensor installed on the truck chassis work as a detector for nearby obstructions.
In the U.S., the AGV industry is centered on the Midwestern states, which are close to the auto industry of Detroit, paper and beverage industry of Wisconsin, and manufacturing center of Chicago.
A wide range of industries are swiftly adapting AGVs. Orders for AGVs, which cost anywhere between $700,000 to $1 million, have seen an upward trend as automation has become common in distribution facilities and warehouses.
A turning point for the AGVs came when Amazon, in 2012, acquired Kiva Solutions, an automated material handling company, for reported $775 million. The number of manufacturers has now doubled, seeing the trend. At industry trade shows, multiple new companies are coming to highlight their AGVs. If the trend says something, it is: the AGV days have arrived.
