Automated Guided Vehicle (AGV)A Computer-Controlled, Non-manned, Electric

Powered Vehicle Capable of Handling Material

An automated guided vehicle or automatic guidedvehicle (AGV) is a mobile robot that follows markersor wires in the floor, or uses vision or lasers.

They are most often used in industrial applications to

move materials around a manufacturing facility or awarehouse

Robot

A robotis a mechanical or virtual agent, usually anelectro-mechanicalmachine that is guided by acomputer program or electronic circuitry.

Robots can be autonomous or semi-autonomous andrange from humanoids to industrial robots,collectively programmed 'swarm' robots, and even

microscopic nano robots. By mimicking a lifelikeappearance or automating movements, a robot mayconvey a sense of intelligence or thought of its own.

Types of AGVS

Driverless trains: It consists of a towing vehicle thatpulls one or more trailers to form a train.

AGVspallet trucks: Pallet trucks are used to movepalletized loads along predetermined routes.

Unit load carriers: These are used to move unitloads from one station to another.

Types of navigation in AGVS

Wire Embedded in floor

Optical Tracks contrasting color

Inertial Gyro with magnets in floor

Laser Triangulation from reflective targets


12/19

Atmega 16 microcontroller is used.

Medium cost

High speed grades 0 - 16 MHz

High-performance

operating voltage 4.5V to 5.5V

UART(Universal Asynchronous Receiver/Transmitter)

Crystal oscillation speed:16 Mhz

MICROCONTROLLER


13/19

MOTOR DRIVER

Controls motor using Logical signal from the

microcontroller

Controls motor speed using Pulse width modulation

Electronically commands the motor to go forward,

reverse, brake, and coast.

MOTOR

Actuator that converts electrical signal to rotationalmotion

Contrary to usual belief it is an open loop control, Anew technology of Back Emf interference is used toapproximate a closed loop

Movement mechanism

The robot consider to be in origin

It can move through the lines with the box enclosed bythe lines assumed to be machines.

By using geometry path can be calculated by the centralcomputer which is sent wirelessly to the AGV.

The microcontroller receives the path from the

computer after the following considerations The path is not currently in use by other AGV

The path does not cross the lines being used by otherAGV.

The path is under maintenance

Safety Most industrial-use AGVs travel at a speed between 100

and 300 feet per minute.

Common AGV Applications Raw Material Handling

Work-in-Process Movement

Pallet Handling

Finished Product Handling
