Evolving your CYBUG SCARAB
Check
out these add-on circuit boa
rds to enh
ance
your scarab
s behaviour...
HBF-1: Hunger Instinct
This higher
brain fu
nction
continually monitors
the robots
ene
rgy
level an
d
change it’s behavior from
photo-phob
ic ( afraid of light ) to photo-tropic ( at-
tracted to light ) as necessary. W
hen ene
rgy is low, your CYBUG will be drawn to
the light of
the S
UNFLOW
ER for a m
eal, but once full, it must leave the water-
ing hole for the saf
ety of dark areas.
HBF-2: Predator Instinct
This higher brain fun
ction ad
d on board
for the CYBUG adds a keen se
nse to th
e
basic platform which allows your robot to spot and
chase any CYBUG ( or other
robot ) which carries th
e transmitter board
. The transm
itter boa
rd (also in th
is
kit ) produce
s an
d infra-red digital sce
nt which betrays th
e pre
y.

The CYBUG SCARAB is a ne
w, exciting typ
e of educational kit. It
combines elemen
ts of electronics, robotics, m
ech
anics, and
biology
in a
unique
and
interesting form
. It’s instructional, very easy to build, and
fun to m
odify and customize.
The operating
CYBUG SCARAB behaves as a living organ
ism, with behavior and
instinct
designe
d in it’s circu
itry. The rob
o-organ
ism is nocturnal ( m
ost active at night ) an
d can
be configured to be photo-tropic ( light se
eking ) or photo-phob
ic ( light avoiding ). A
quick adjustment cause
s th
e Scarab to behave aggressively as a predator, or tim
id and
slow m
oving like a herb
ivore. N
o tw
o Scarabs are exactly th
e same and
you will come to
recognize the unique characteristics of each!
The S
carab is just one
member of a new rob
otic eco
system w
hich parallels nature in a
unique
and
fascinating
manner while educating it’s owne
rs in fun
dam
entals of electronics,
robotics, biology, and control systems.

you will perform
while constructing this kit. A good solder connection will ensure a
solid electrical connection between the part and the circuit board. A bad solder
joint can prevent an otherw
ise well assembled kit from functioning properly.
It is simple to make a good solder connection if you follow a few simple rules:
few simple rules:
few simple rules:
few simple rules:
1.
Use the right type of soldering iron. A 25 to 40 Watt pencil type iron intended
for electronic work with a 1/8” pointed tip works best. Use a rosin-core solder
on diameter approximately 0.032” and a 60/40 lead/tin ratio.
2.
Keep the soldering tip clean by wiping it frequently on a wet sponge or cloth:
then apply solder to the tip to give the entire tip a wet look (tinning the tip).
When solder tends to “ball” or does not stick to the tip, the tip needs to be
cleaned and re-tinned.
How to Solder

How to Solder
How to Solder
• Install the component on the board, flaring the leads on bottom side slightly
(so the part does not fall out when the board is flipped!) Flip the board upside
down.
• Touch the freshly tinned soldering iron to the point where the
component wire meets the board. Hold for 1 second!
• Touch the solder to the opposite side of the component wire/
board junction and allow solder to melt and surround pad entirely.
• Remove the solder, then remove the soldering iron by drag-
ging the iron up the component wire.
• Clip off excess component wire with side-cutters.
