3. AGV is a material
handling system that
uses independently
operated, self-
propelled vehicles
guided along defined
pathways.
6. 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.
7. • 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.
8. • 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.
10. • 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.
11. 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.
12. 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.

14. 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

15. 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.
17. Reduces the labor cost.
Flexible.
Intelligent.
Less Time consuming
Can significantly reduce production & warehouse costs.
Transforming the materials handling industry.
18. • 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.

20. 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.
21. 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
22. • 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
23. 1) Storage structure
2) SIR machine
3) Storage modules (e.g., pallets
for unit loads)
4) One or more pickup-and-deposit
stations
5) Control system
24. • Warehousing and distribution operations
• AS/RS types: unit load, deep lane (food industry)
Unit load storage and retrieval
• AS/RS types: mini load, man-on-board, item retrieval
Order picking
• Helps to manage WIP in factory operations
• Buffer storage between operations with different
production rates
• Supports JIT manufacturing strategy
Work-in-process storage
