INSTRUCTIONS
1. Trace the patterns for the body and legs ( Page 5) on to the plywood sheet (1) Use a macine vice to hold the body when drilling
theside holes 15/20 mm deep. It importnat that these holes are drilled opposite each other otherwise the robot will not walk
correctly!
Trace the body and arms ( See page 7) on to the plywood sheet (2) Sand to nish Drill the 3mm holes and countesink 2mm
deep as shown in the plan
Construction:
2. Glue the head on the
body as shown as shown in
diagram 1 ( Glue the shaded
area )

4. Insert a machine screw (11) in the 4mm hole
in the gears and tighten with a stop nut (12)

3. Take two gears (15) and
drill them out to ø4mm as
shown in (Dia 2)

5. Now insert in both gears (15) a machine screw(11) as shown and two washers (13)
in the holes in the lower body (See dia.3) Tighten the machine screw so that it turns
without play.
NOTE:
The thread in the hole will be
cut by the machine screw as it is
inserted!

6. Glue the arms ( Dia 4) under the opening in the legs. Glue the legs with the countersink underneath, and leave to dry well.
Glue the second part in a mirror image to the rst. Fix the feet from underneath with screws (9)

7. Mark 20mm on each side of the motor axle (3) with a waterproof pen (Dia 5). Place the axle in a vice and saw o to the
previous mark. Clean up the saw cut with a le to remove any burr (Dia.6 ) Do the same with the other side
Dia.5
Dia. 6
Insert a machine screw (10) in the top opening in the legs and x with a stop
nut (12) so that the can move smoothly in the opening!
Slide on the machine screws (10) a gear
on each side (15) between two washers
(13). Mount the legs on the machine
screws (10) and add a stop nut (12)
At the same time insert the machine
screw (10) in the side hole in the body
(The machine screw will make its own
thread!)
Note:
The countersink holes
face downward!
Note:
After addding the legs turn the gears. By turning the two gears they should be set at 180 degrees. ( One drive screw up
and the other facing down ) By turning the gears equally you can test the mechanical function. The legs should move
smaoothly and not catch on each other. Should they rub or catch, test the function once more.

Make a notch at 8mm on the
axle so that the gear will be
held tight (s. Dia.7)
Glue a reducer (16) in both
of the gears (14) with instant
glue.(Dia. 8)
Squeeze some glue in the
reducer and gear so that it re-
mains tight on the axle. (Dia.9)

8. Note:
Arrange the legs, so that the machine in thelarge gears,
which drive the legs, are set at 180 degrees. ( Dia 10)
Mount the motor and gearbox (3) with the two small
gears (14) on the front of the body with 4 screws (9) The
small gear must mesh with the larger gear (15) (Teeth
engage). When tightening the screws you should be
careful that it does not slip and that the larger gears are
still at 180 degrees. (s. Dia.11)
Once the gearbox is in place test the motor with a bat-
tery (3volt) Plus to the top motor contact .If all is correct
the legs will move one after the other (180 degrees )
and not catch aginst each other
9. Fix the battery holder (6) to the back
of the body (6) using 2 screws (9) (see
Dia 12.)
10. Fit the micro switch (7) in the mouth
with glue (s. Dia 13)
Dia.10
NOTE!
Should the legs not function properly, remove it from the power source immediately. Check over the mechanical function
manually once more.

11. Fit the two Light Emitting Diodes
(LEDs) (8) as eyes in the 5mm holes
in face, secure instant glue. Make
sure that the shorter legs (Catho-
de) ,on the LED side with at, face
upwards. (s.Dia 14)
Cathode=short
Flattened edge side

INSTRUCTIONS
Wiring:
Note:
The wire connections can be twisted together but it is better if they are soldered.
12. - Join the anode legs of the LEDs together (Solder or twist )
- Take the red lead from the battery holder (6) cut it to ca. 20mm long and then remove the insulation and tin the end.
- Cut a 100mm length of red cable (5) remove the insulation from both ends and tin the wire ends. Solder one end
the Anode of the LED and the other to the red battery cable
- Cut ca 150mm from the red cable (5) remove insulation and tin both ends
. Solder one end to the red cable of the battery holder. Guide the other end through the hole in the body through to
the front , slide over the end half of the plastic shrink sleeve ( in gearbox packet ) Then solder the end of the cable
to the lower connection on the motor (3) Make sure that the cable does not snag any of the gears. Finally heat the
shrink plastic as insulation ( Use a hot air gun )
- Take the remainder of the red cable and remove the insulation from both ends and tin the wire ends.Wind the cable
around a pencil to make a coil . Then pull it lightly apart.
Solder the ends to the Cathode connections on the LED(8). The coil should pass over the robot head
- Cut a 150mm length from the black cable. Strip and tin the wire ends ,solder one end to the left connection the
switch . Guide the other end through the robot body , add the shrink sleeve insulation and solder the end to the
free connection on the motor . Use hot air gun to shrink the plastic tube.
- Cut ca. 40-50mm from the black cable, strip and tin both of the ends. Solder one end to the middle connection on
the switch (7) and the other to the black battery cable
- Take the remaining cable. Strip and tin the wire ends . Wind it around a pencil to make a coil . Connect one end to
the left hand side of the switch (7) The other end to the Cathode of the right hand LED ,guiding the coil of cable
over the robot head
