What is AGV?
AGV is a material handling system that uses independently operated, self-propelled vehicles guided along defined pathways.
1. Automated guided vehicle (AGV)
2. Load transfer positions
3. Load handling equipment
4. Load devices
5. Guide track
(laser, inductive, optical)
6. Data transmission

AGV System
Types of AGV
Types Of AGV
Driverless Trains
AGV’s Pallet Trucks
Unit Load Carrier
Driverless Trains It consists of a towing vehicle that pulls one or more trailers to form a train.
This type is applicable in moving heavy pay loads over large distance in warehouses or factories with or without intermediate pickup and drop off points along the route.
It consists of 5-10 trailers and is an efficient transport system.
• Pallet trucks are used to move palletized loads along predetermined routes.
• The capacity of an AGV pallet truck ranges up to several thousand kilograms and some are capable of handling two pallets.
• It is achieved for vertical movement to reach loads on racks and shelves.
AGV Pallet Trucks
• These are used to move unit loads from one station to another.
• It is also used for automatic loading and unloading of pallets by means of rollers.
• Load capacity ranges up to 250 kg or less.
• Especially these vehicles are designed to move small loads.
Unit Load Carriers
Types Of Navigation In AGV
Navigation System
Wired Navigation
Guide Tape Navigation
Laser Target Navigation
• The wired sensor is placed on bottom of the AGV’S and is placed facing the ground.
• A slot is cut in the ground and a wire is placed approximately 1 inch below the ground.
• The sensors detects the radio frequency being transmitted from the wire and follows it.
Wired Navigation
Guide Tape Navigation
The AGV’S use Optical / Chemical / magnetic tape for the guide path.
The AGC’S is fitted with the appropriate guide sensors to follow the path of the tape.
It is considered a “passive” system since it does not require the guide medium to be energized as wire does.
Laser Target Navigation
The AGV’S carry’s a laser transmitter and receiver on a rotating turret.
The laser is sent off then received again the angle and distances are automatically calculated and stored into AGV’S memory.
The AGV’S has reflector map stored in memory and can correct its position based on errors between the expected and received measurements.
Laser Target Navigation
Man / vehicle functions– Inputs made via
operator panel with its keyboard and display
– Destination input to the vehicle
– Plug-in manual control and diagnosis module
Route (destination) finding– High vehicle intelligence– Travel route topology
stored in the vehicle– Destination code
processing– Load-sensing and empty
location recognition
Guide track following Guided movements using:
– optical track– inductive track– "free-flight" (partly guide-
trackless)– "free-navigation" (guide-trackless
Data exchange– Infrared– Radio
Special functions– Battery reserve
monitoring– Control of battery
charging– Obstacle recognition
Load handling– Load acceptance– Load depositing– Load monitoring– Load transfer
synchronization
Travel control– Speed– Safety gap maintenance– Collision protection
Vehicle Functions
Zone Control
• Zone control to implement blocking system.
• Zones A, B, and D are blocked.
• Zone C is free. Vehicle 2 is blocked from entering Zone A by vehicle 1.
• Vehicle 3 is free to enter Zone C.
Zone Control
Emergency stop
Status indicator
Obstacle sensor
Protective bar
Flasher
Protective bar
Photobarrier
Audible signal
Side protectionrails
Safety Elements
Reduces the labor cost.
Flexible.
Intelligent.
Less Time consuming
Can significantly reduce production & warehouse costs.
Transforming the materials handling industry.
Why Consider AGV ?
Application Of AGV
• AGVs are commonly used to transport raw materials such as paper, steel, rubber, metal, and plastic.
Raw Material Handling
• Work-in-Process movement is one of the first applications where automated guided vehicles were used, and includes the repetitive movement of materials throughout the manufacturing process.
Work in Process
Movement
• Pallet handling is an extremely popular application for AGVs as repetitive movement of pallets is very common in manufacturing and distribution facilities.
Pallet Handling
• Moving finished goods from manufacturing to storage or shipping is the final movement of materials before they are delivered to customers.
Finished Product Handling
Automated Storage / Retrieval System
What is AS/RS ?
An automated storage & Retrieval system can be defined as a storage system that performs storage and retrieval operations with speed and accuracy under a defined degree of automation.
It consists of a variety of computer-controlled systems for automatically placing and retrieving loads from defined storage locations.
Objectives of AS/RS
To increase storage capacity
To increase storage density
To recover factory floor space presently used for storing work in process
To increase labor productivity in storage operations
To improve safety in storage function
To improve control over inventories
Types Of AS/RS ?
• Large automated system designed to use S/R machines to move unit loads on pallets into and out of storage racks.
Unit load AS/RS
• High-density unit load storage system, designed to store large amounts of stock with relatively little amounts of stock types.
Deep-Lane AS/RS
• Smaller automated system designed to move smaller loads into and out of storage bins or drawers.
Mini-load AS/RS
• Uses personnel to pick items from racks or bins, reducing transaction time.
Man-on-board AS/RS
• Items to be moved are stored in single file lanes, rather than in bins or drawers.
Automated item retrieval system
• Same principle of using a center aisle to access loads is used except that the aisle is vertical. Helps to save floor space
Vertical lift storage modules
Components Of AS/RS
1) Storage structure2) SIR machine3) Storage modules (e.g., pallets for unit loads)4) One or more pickup-and-deposit stations5) Control system
Application of AS/RS
Unit load storage and retrieval
• Warehousing and distribution operations• AS/RS types: unit load, deep lane (food industry)
Order picking
• AS/RS types: mini load, man-on-board, item retrieval
Work-in-process storage
• Helps to manage WIP in factory operations• Buffer storage between operations with different production rates• Supports JIT manufacturing strategy
