STAGE 59:
TEST ROBI’S NECK,
BACK AND ARMS
Use the CPU board to test Robi’s neck, body and arms,
before fittin the velvet pads supplied in this stae to his feet.
This stae beins with you testin all the
servos of Robi’s neck, back and arms
toether, to ensure they all work before
you seal them inside Robi’s body. You will
then start buildin up the frame that will
hold both of Robi’s head servos, by
securin this to the neck base and servo
assembly via the servo itself. Finally, you
will attach the velvet pads supplied in
this stae to the soles of Robi’s feet.
Unlike the double-sided adhesive pads
used in Pack 9, these pads come in a left
and riht shape, so make sure you use
the correct one!

FASTEN THE NECK PLATE
TEST THE SERVOS
Use an M2 x 6.2mm pan-head screw to secure the part,
but do not tighten it too much, as the plate needs to be
able to move. You received a number of screws with this
stage, so make sure you use the correct one – this one
was part number 8 in the list.
Hold the body as shown, then push the switch
to the ON position.
Connect the battery’s connector to the socket
marked CN1 on the power distribution board. Make
sure the battery is charged (see box, above).
Now take the free connector on the body’s power/switch cable
and fit this into CN3.

Still holding the battery in place,
turn the switch ON. Note: Robi’s
arms will move as soon as the
power is switched on!
Slide the battery into the space next to the back servo, making sure all the
connectors stay in their sockets. Hold the battery in place.
When the power is connected, Robi will perform a movement test of his arms, by setting them to their starting, or neutral,
position, stretching them outwards from the elbows, then bringing them back to the neutral position.
Next, Robi’s upper arms will lift outwards – and while this
happens, his neck servo will pan to the right and back.
Finally, Robi’s shoulders will extend his arms forward
over his chest – and the shaft of his back servo will
rotate to the left.

When the tests described on the previous pages are
complete, Robi will return to his neutral position and you
will hear him say ‘OK!’ This is to test his speaker. Turn the
switch back to OFF, and disconnect the switch cable and
battery from the power distribution board.
Line up the head servo frame to the neck
servo, as shown.
Set the frame on top of the neck servo, so that the circled holes align
with the free ones on the neck servo. Then insert and tighten two
M1.7 x 24mm pan-head screws into these holes.
Now locate the circled hole in the top of the frame. Insert an M2 x 6mm pan-head screw into this hole to
secure the part.

OK!
STARTING
POSITION Each of the white plastic
connectors has a small barb
on one side, which holds the
connector securely in its
socket. To unplug a connector
easily and safely, press the
barb inwards – never pull on a
connector without doing this!
ATTENTION! !
Both arms were tested in
Stages 43 and 44, so if they
do not work now it is most
likely a problem with the
connection to the CPU, so
check/reset this.
Remove the back servo’s
cable from the CPU and
check to see if the arms start
working.
Consult the troubleshooting
guide of this stage.

FIT THE HEAD LEVER
Take the head lever and fit the ring nut into the hole in its longer arm,
from the angle shown. The ring nut should fit perfectly.
Take an M3 x 8mm pan-head screw and insert it through the circled
hole in the inside of the head servo frame, entering from the left. Turn
the screw through this hole so that it travels through the ring nut in the
lever and out to the other side.
With the ring nut still in position, slide the
lever into the space in the middle of the
head servo frame. Its shorter arm should
be at the rear of the assembly, pointing
out towards Robi’s right arm.
Holding the ring nut in its hole, line up the
lever to the head servo frame, oriented as
shown above.

Make sure the test board is switched OFF, then
connect its own servo cable to it.
Turn the board ON. The LEDs should flash, and then leave the
1 LED lit alone.
324

23 24
Press the TEST/SET switch: Robi’s head should rotate 45° to the left, stop, then
move back across to 45° to the riht, before returnin to its oriinal position. The
next step is to set the servo’s ID number, so keep the power on. If the test does not
run, or if the LEDs flash rapidly, refer to the HELP box in Stae 8.
Althouh this servo has been used for Robi’s
neck durin the testin process, it will be his
forward-tiltin head servo when fitted, with
the ID number 15. To set this, press UP 14
times, so that the 10 and 5 LEDs liht up.
Press and hold down the TEST/SET button
for a few seconds. The 10 and 5 LEDs
should flash, then remain lit. The ID number
is now set.
If the test does not
run, check the servo
cable’s connector,
and ensure that the
battery is charged.
ID=15
25 It is vital that Robi’s servos are set correctly,
so it is always a ood idea to check that you
have set the intended ID number afterwards.
To do this, leave the servo connected, then
switch the power OFF, then back ON. Only
the 1 LED should liht up.
26 To check the ID number, press TEST/SET briefly. Now the 10 and 5
LEDs should liht up and the servo shaft should repeat the rotations
seen in the test. Note: if anythin is amiss, you can bein the settin
process aain from Step 23.
CHECKING THE ID NUMBER
It is normal for the 1 LED to
light up when you switch on.
It will only change to give you
the ID number of the servo
when you press TEST/SET. If
you made a mistake, or set the
wrong ID number, you can reset
it by going through the setting
procedure again.
As you will have seen in the previous few packs, the process of
checking and resetting a servo’s ID number once fitted can be
fiddly and time-consuming, so be sure to get it correct now!

FITTING THE FOOT PADS
PREPARING THE SERVO CABLE
27 28
Match the riht foot pad to the sole of Robi’s riht foot, then,
when you are sure that they alin, peel the backin away to
the middle. Press the heel of the pad onto the back of the
sole, then smooth it down from the back to the front, peelin
the rest of the backin away as you do.
Make sure that the pad fits exactly: if it doesn’t, peel it away
and reset it. Once you are happy with it, repeat the process
for the left foot and pad.
29 30
As you have done previously, identify the side of this
stae’s servo cable connector that has PUSH marked
on it (circled).
Apply a pad to the connector on this side. Repeat for the
other end of the cable.
If you want to delay fitting
the pads until the cable is
used in the build, you may
do so.

TROUBLESHOOTING
In this section, we look aain at what to do if the movement test carried out in this stae does
not o as described. As the arms have been tested previously, we will focus on the operation
of the neck and back servos, as well as the speaker, from which Robi says ‘OK!’
Before dismantlin the assembly to check its individual servos, check the other electrical components used in the test.
HEAD/NECK/BACK SOCKET
CHECK THAT THE CABLE IS CONNECTED TO
THE CORRECT SOCKET ON THE CPU
CHECK THAT THE SERVO CABLE IS
SECURELY CONNECTED TO THE CPU
CHECK THAT THE
BATTERY IS CHARGED
Ensure that the back servo
cable’s connector is sittin
securely within its socket.
Remove and replace it carefully
if need be.
The socket farthest from
the micro SD card slot on
the CPU board will hold the
servo cable runnin from
the back servo.
The test will only run if sucient
power is received from the
battery, so make sure the battery
is fully chared (see the Close-
Up box earlier in this stae).
INITIAL CHECKS
Neck stand (Stage 53)
Alon with the Phillips screwdriver
supplied with Stae 2, you will need
the followin:
IF NEITHER THE NECK NOR BACK SERVOS MOVE,
OR IF ROBI DOES NOT SAY ‘OK!’
If neither the neck nor the back servo moves when you start
the test, it is probable that there is a misplaced connection,
so o back and check these. Similarly, if Robi does not say
‘OK!’ at the end of the test, you should check the connection
between the speaker cable and CPU board.
THE BACK SERVO
THE SPEAKER
Follow the assembly of Steps
14-19 of Stae 58 in reverse, and
check the back servo’s connections
carefully. If both were sound,
disconnect it from the neck servo
and check the servo’s ID number
(ID=12), resettin it if necessary.
If Robi does not say ‘OK!’ at the
end of the test, check the connection of the speaker cable to
the CPU – done in Step 15 of Stae 57.
IF ONLY ONE SERVO MOVES
If one servo moves but the other does not, it is likely that one
of the ID numbers has been set incorrectly.
Should you need to disassemble and reset Robi’s neck or back
servos, see Stae 58 (for the back servo, ID=12) and/or Stae
54 (for the neck servo, ID=13).
327

You will be usin parts from the
previous staes, so be sure to have
these to hand before beinnin.
STAGE 60: PREPARE
AND FIT ROBI’S
HEAD SERVOS
Prepare Robi’s second head servo then fit it, alon with the
one from the previous stae, to his head servo frame.
There are two servos inside the upper
part of Robi’s head, ID=14 and ID=15.
Both are set onto the head servo
frame that you fitted and wired over
the previous staes, and they will work
in tandem with the internal lever and
head base to make Robi’s head tilt
forward and back (in the case of
ID=15) and side to side (ID=14). As
ever, take care when handlin open
servos, and make sure you set the
correct ID number.

3Hold the open servo with the circuit board facing upwards. Fetch the
servo cable fitted with protective pads in the previous stage, and press
one of its connectors into the socket circled in red, as you have done
before. It does not matter which end of the servo cable you use.
Gently lift the cover away, takin
care not to force it or damae
the circuit board underneath.
1Take out the four screws holdin the servo’s removable
cover in place, and keep these safely to one side.
As ever, it is very
important that the
electronic parts
exposed by removin
the servo’s cover are
not touched in any
way. Make sure to hold
the open servo by its
sides, and if you put it
down on your work
surface durin the
assembly, do this with
the open side facin
upwards.
4Pass the free end of the servo
cable throuh the circular hole in
the removable cover, as shown.
56
Press the cover back into place
on the servo’s main housin.
Fasten the cover back into place
with all four screws, but only
lihtly, as you will be removin
them aain at a later stae.
TIP!
TIP!
This servo cable had
protective pads fitted
to its connectors in the
previous stage, but if you
find it difficult to attach
with a pad in place, it is
possible to fit the pad
afterwards. If you choose
to do the assembly this
way, be especially careful
not to press down on the
circled projection, next to
the cable, as you do so.
329

TESTING THE SERVO
8
7Take the neck stand and make sure the power pack is
turned OFF. Carefully unplu the black servo cable from
the socket on the left of the test board, and attach the
servo cable connected to the servo in Step 3.
With the servo connected, switch the power to ON. After
the LEDs blink twice, only the 1 LED should liht up.
9To test the servo, press the TEST/SET switch: the servo’s shaft should rotate 45°
to the left, stop, then move back across to 45° to the riht. The next step is to set
the servo’s ID number, so keep the power on. If the test does not run, or if the LEDs
flash rapidly, refer to the HELP box in Stae 8.
SETTING THE ID NUMBER
10 Next, you will set the ID number
of the servo usin the test board,
as you have done before. Each
time you press the UP switch, the
ID number increases by one, and
the result is displayed by the two
banks of LED lihts. The top row
reads in tens and the bottom in
units. For example, to set the ID to
14 as you will do in this stae, you
press UP 13 times. This will liht
up the 10 and 4 LEDs. (If you
overshoot, press the DOWN switch
to take it down one step at a time.)
When the ID number is correct,
you set it by pressin and holdin
the TEST/SET switch.

Pressin DOWN will adjust this if you
overshoot while doin this.
Once the numbers are correct,
press and hold TEST/SET for a few
seconds. The LEDs will blink, then
stay lit, confirmin that the ID is set.
13 It is vital that Robi’s servos are set correctly, so it is always a ood idea to check
that you have set the intended ID number afterwards. To do this, leave the servo
connected, then switch the power OFF and back ON aain. After blinkin, only the
1 LED should liht up.
14 To check the ID number, press TEST/SET
briefly. Now the 10 and 4 LEDs should
liht up and the servo shaft should repeat
the rotations seen in the test. Note: if you
find that a servo has the wron number
assined to it, o back and repeat the
settin process in full.
CHECKING THE ID NUMBER
It is normal for the 1 LED to
light up when you switch on.
It will only change to give you

ROBI’S HEAD, NECK STAND AND TEST BOARD
Robi’s head contains a number of his most vital electronic components, which you will
bein to add in the comin staes. The first components you will fit, in Stae 62, are the
infrared sensors that identify movement and are set into the centre of his eyes. Then, later
on, you will add the LEDs that illuminate his eyes and liht up his mouth to ive him his
expressive character. The head will also hold key parts used for his voice-reconition
capabilities, and more!
Robi’s head
Althouh you have disassembled the neck stand in recent
staes, you will be usin it and the test board that it holds
aain, so keep it safely until then!
USING THE NECK STAND AND TEST BOARD
Althouh you have removed the scarf, neck servo and head, you will continue usin the neck stand, and the test board it
holds, to check or reset servos’ ID numbers. The process for doin this will be the same as before, thouh is actually a
little more straihtforward, as you can now use the neck stand’s existin servo cable (previously used to connect the
neck servo) to connect to the servo in question. The steps for performin a servo test this way are found below.
1Ensure the neck stand’s servo
cable is connected securely to
the test board, then set the
other end to the servo you wish
to check/reset.
2Bein the process of testin/
resettin the chosen servo in
the usual way.
3To complete the test, simply turn

TEST THE NECK AND HEAD SERVOS
32
35 36
37
33 34
Push the switch on the scarf
to the OFF position.
Turn Robi’s switch ON.
The test will bein as
soon as power is turned
on, so be prepared!
As well as the servos
focused on in these steps,
the arms will also move,
so hold Robi in a way that
will not interfere with this.
The test will bein once the power is turned on.
First, observe the left-hand head servo, ID=14,
which will return to its neutral position, then
rotate a small way clockwise, raisin the D-cut
section upwards. Look very closely, as the
movement will be minimal (inset). Robi’s neck
servo, ID=13, will then rotate. Once that is done,
Robi will say ‘OK!’
While the neck servo is performin its
rotation, Robi’s second head servo,
ID=15, will also run its test, this time
rotatin anticlockwise a little to
aain raise its D-cut upwards
(inset). Once you are happy
with the test, disconnect
the power.
Connect the battery to the power
distribution board, in socket CN1.
Now connect the power/switch cable to
socket CN3.
