The OEM offices, workshop and warehouse will be closed for the Christmas period. See our full closing times and last order details.
AGV is short for Automated Guided Vehicle. AGVs are automated and computer controlled transportation robots that can be used for a range of tasks. Common types of AGVs include Automated Guided Forklifts and Automated Guided picking robots.
You typically see AGV’s in manufacturing and warehousing but can also be used for inspection, transportation, military and exploration applications.
AGVs can be designed to conduct a wide range of functions. These include remote handling, packing & picking, scanning, measuring & monitoring, signalling & detecting, machine vision & transportation, to name just a few.
As well as being able to conduct multiple tasks, AGVs are equipped with the best safety technology meaning there is little to no chance of collisions or unsafe conditions.
You typically see AGV's in a warehouse used for logistics, optimising productivity and reducing labour costs at the same time.
Now that we have established what an AGV is and the benefits of using AGVs, we will go through some of the important design considerations.
The industrial automation specialists at OEM Automatic can advise on and supply a wide range of elements suitable for AGVs.
Let’s look into some of the components and some of the highly recommended brands that go together.
For your AGV to see, you must give it eyes. Cameras can be used to capture objects and scenes in 3 dimensions and are highly useful in logistics and AGV’s. This means that you can get 2D and 3D images in high resolution within a small compact system. They can be used to generate depth data and measure distance.
Key Facts:
A typical use would be a warehouse where several AGV’s with cameras are moving in a confined space.
We recommend Baslers’ TOF Camera (Image 1), which is packed with advanced and useful technology.
Traceability improvements lead to performance improvement, transforming all capabilities in logistics and increasing productivity. You would typically see 1D and 2D barcode scanners in a warehouse and on an AGV. These help to track information and data, helping you keep track of what is happening.
Traceability is the biggest advantage of using a barcode scanner on an AGV, achieving higher productivity. Some are faster than ever and have great visual quality. Not forgetting they can be extremely configurable.
Key facts:
Take a look at our Datalogic Matrix 320 barcode reader (Image 2).
Being able to sense and detect is one of the most practical, time saving and efficient purposes of an AGV, which eliminates the use of labour. Components that sense and detect can be used for platform load, weight detection, movement, presence and position detection in the warehouse. These features are also used for the critical safety of the AGV and minimise any potential risk.
Safety laser scanners can be mounted onto AGV’S, and warning zones can be programmed to automatically change the vehicle's position, speed, and direction. Additionally, there are versions with encoder inputs to allow safe measuring of the speed of the vehicle. The purpose is to ensure staff safety whilst improving efficiency and Is what makes the AGV so special and innovative.
Key Facts:
See more about our Datalogic Safety Laser Scanner, which is an innovation in workplace safety (Image 3).
LIDAR (Light Detection and Ranging) uses laser-based time-of-flight (ToF) technology to construct a 360-degree view for the guidance of AGV’S. These are used purely for guidance and navigation of AGV’s and can also measure distance, making them super important in terms of manoeuvring the robot in the right direction.
Key facts:
Datalogic provides Lidar guidance scanners that use infrared laser technology and achieves navigation of AGV’s moving up to 2 m/s and a scan rate of up to 25 Hz and 60,000 measurements per second (Image 4).
Using this and the safety laser scanner together offers a complete solution to safety and sensing!
Electrical components can be found on the inside and outside of an AGV. Many different features aid control and make the electronics work, so we are touching on a few.
Safety is a priority! Emergency stops must be a part of any AGV, and you must have a completely reliable stop device. Safety is of utmost importance, and this is a simple but essential device that can be pulled/turned or key-controlled depending on the product.
An Emergency stop solution consists of a mushroom head designed to ‘push’ with the action of a sufficient force to open the contact and triggers an irreversible locking of the opening. Then, an emergency stop signal gets cancelled only by deliberate manual resetting of the mushroom head.
Key Facts:
Our BACO emergency stop solutions can be found here and meet EIC standards for emergency stop actuators. You can choose from 3 types of emergency stops and 3 types of mush-room heads. (image 5)
A beacon should be visible on an AGV to show signals. A regular beacon would be suitable for this and is designed for maximum signalling effect, and it is also very easy to mount. There is also an option for a beacon and sounder combo for maximum effectiveness.
Key Facts:
Check out AUER’s beacon range, which has two light module designs. The R Series is a powerful, flexible and robust system. (Image 6)
Cable glands suitable for use on AGV’s provide EMC shielding that achieves an effective contact to the cable screen.
Key Facts:
Agro’s EMC Cable glands guarantee complete control during installation, compensating for tolerances in shielding thicknesses to make a secure and reliable connection to the cable screen. (Image 7)
An AGV to move and perform physical activities will require motors and other related components such as linear actuators. We will look at a few particular products that relate to AGV’s big and small.
A simple DC powered gear motor may be used for applications such as internal flaps, doors, or movable dividers that present a low power requirement, up to fully networked high power brushless traction drive motors. Depending on the type of AGV you have, it is best to work with us to find the right components that you need. (image 8)
Key Facts:
OEM Automatic can provide a wide range of motors and gear-motors suitable for AGV applications from a variety of manufactures including Crouzet, Minimotor and Doga.
Linear actuators can be used for many operations on and within AGVs. We can provide 35mm long miniature linear actuators to operate an internal door or camera lens cover, up to a large capacity unit for lifting components or replacing hydraulic lifts – all depending on the type of AGV you have.
Key Facts:
We suggest looking into Actuonix for linear actuators.
Solenoids and electromagnets are used to lock compartments and security bolts. You’d use these for interlocks, holding doors/panels/dividers and cage locks.
Key facts:
We recommend NAFSAs range of extensive electromagnets. With their specialist knowledge in the electromagnet field, they lead the way in this industry. (Image 10)
A mere insight into a few of the components that make an AGV what it is today. Logistics, manufacturing and distribution are becoming unimaginable without Automated Guided Vehicles. Say bye to inefficiency, human error and time-consuming processes!
