Introduction
 Cybot
is a
small
3 wheeled
robot. It has
two
motors at the
back which
provide the
drive and
steering of
Cybot. At the
front is a free
wheel castor,
which is able to
rotate 360o.
Cybot uses two
type of sensors:
light and
ultrasonics.
Light is
detected by
using two LDR
(Light Dependant
Resistors). The
resistance of
these devices
change depending
on the amount of
light falling on
them.
There are four
ultrasonic
sensors. These
emit a high
pitch sound. If
the sound hits
an object, it
will reflect the
high pitch
sound, and Cybot
will know that
it is there.
Depending on the
mode, Cybot will
either follow
the light/object
or avoid it.
Cybot is
controlled by a
main
microcontroller,
manufactured by
Elan
see Links bellow
We intend to
provide
information on
the Cybot, along
with ideas for
modifying it.
Part of the
modification is
to add new
sensors and to
re-program the
microcontroller
that comes with
Cybot. The only
snag with
the microcontroller
is that it
cannot be
re-programmed.
However, it can
be changed for a
Microchip PIC,
which can be.
However, We
appreciate that
not many people
have experience
in the PIC, so
that is why we
have included a
tutorial on
programming a
PIC, along with
how it can be
interfaced with
Cybot.
Don't worry if
you have never
done anything
like this
before, it is
easier than you
think!!
