ROAD FOLLOWER VEHICLE
[attachment=40575]
INTRODUCTION
One of my friend working for B.H.E.L asked me once ,can you
design a control circuit forth vehicle so that the vehicle be operated without
driveron the road. had lot of trouble With the local union, and sometimes drivers
do not perform the way they are expected. Their requirement was to convey a
rawmaterialfrom point A to point B in a circular fashion.Road reserved only for
this purpose.One vehicle normally takes 150 trips in a day and they Want to
increase this frequency. There was lot of trouble with designing real time due to so
Many factors, but I kept in mind when my friend asked me to design for them, we
Worked and decided to do the project name
“ROAD FOLLOWER VEHICLE” We have fixed INFRA RED sensors on
fore side facing downward on the robo. The principle of sensors is that black
colour will normally observe the light where other colour will normally reflects the
lights.light source is fixed down ward D1 and D2 are infra red led’s and D4 and D5
are photo diodes reflected light will fall on the photodiode . we also have the
obstractacl IR sensor which will sense the obstracal accure in its path and turn off
both motors and wait to remove the obstacle
ROAD FOLLOWER VEHICLE
ROAD FOLLOWER VEHICLE
ROAD FOLLOWER VEHICLE” has following blocks
They are as follows,
Left & right ground sensor
Motor Driver
Processor AT 2051
Obstacle sensor
Power supply
Left &Right sensor:-
A sensor is a device that measures a physical
quantity and converts it into a signal which can be read by an
observer or by an instrument. There are two sensor one is on right
side and other is on left side. Which observers the light reflected from
Ground.
2. Motor Driver :-
An electric motor converts electrical energy into
mechanical energy in this project we have use two 12 volt dc motor
which has only one function that is to move the vehicle in the forward
direction on the black path.
ROAD FOLLOWER VEHICLE
Processor AT 2051 :-
The AT89C2051 is a low-voltage, highperformance
CMOS 8-bit microcomputer with2K bytes of Flash programmable
and erasable read only memory (PEROM). Thedevice is manufactured
using Atmel’s high-density nonvolatile memory technologyand is
compatible with the industry-standard MCS-51 instruction set. By
combining aversatile 8-bit CPU with Flash on a monolithic chip, the
Atmel AT89C2051 is a powerfulmicrocomputer which provides a
highly-flexible and cost-effective solution to man embedded control
applications.The AT89C2051 provides the following standard features:
2K bytes of Flash, 128bytes of RAM, 15 I/O lines, two 16-bit
timer/counters, a five vector two-level interruptarchitecture, a full
duplex serial port, a precision analog comparator, on-chip oscillator
and clock circuitry. In addition, the AT89C2051 is designed with static
logic for operationdown to zero frequency and supports two software
allowing the RAM, timer/counters, serialport and interrupt system to
continue functioning. The power-down mode saves theRAM contents
but freezes the oscillator disabling all other chip functions until the
next hardware reset.
