2.Attach a connecting rod (large) (C) to an upper triangle
(B).
3. Attach a connecting rod (small) (D) to an upper triangle
(B).
4. Attach a lower triangle (A) to two connecting rods.

Line a rubber foot up with the slit on the
end of one of the lower triangles (A), and
then use the shaft (short) to push the rubber
foot into the hole to attach it. Adjust the
position of the rubber foot so that it lines up
with the middle of the slit. Do the same for
all twelve lower triangles (A) to attach a
rubber foot to each.
Attach the larger joint
on (C) to the largest
joint on (B), and then
rotate (C) 90°
downward.
Line the notches on
(C) up with the
protrusions on (B) to
attach (C) to (B).
Arrange the joint on (D) and
the joint on (B) so that the
protrusions and notches
line up as shown in the
diagram to attach (D) to (B),
and then rotate (D) 90°
downward.
Insert the crankshaft into
the slot in the middle of
the frame. There are three
protrusions on the frame
and a protrusion on the
joints at each end of the
crankshaft. Make sure
that the protrusion on the
crankshaft is facing in the
same direction as those on
the frame. Make two sets
like this.
2. Connect the right leg and crank together with a single-
action rod (small) (E).

The leg should
be attached to
the joint on the

frame as seen
from the side
with the
crankshaft.
Upper joint
Right leg
First, attach the joint on (A) with
the protrusion to the joint on (D),
and then rotate (A) upward to
attach the other joint on (A) to
the joint on (C) with the
protrusion. This completes one
leg.
Attach the largest joint
on the leg to the joint
on the right side of the
frame so that the
rubber foot on the leg
is at the bottom. Attach
(E) to the upper joint
on the leg so that the
protrusion and notch
line up, and then push
the key part on (E)
down onto the crank as
shown by the arrow so
that it snaps into place.
Attach the largest joint on the
leg to the joint on the left side
of the frame so that it is
opposite from the right side,
and then attach (F) to the
lower joint on the leg and push
it down onto the crank that
was attached in Step 2 so that
it snaps into place. When
completing this step, make
sure to position the newly
attached rod so that it is in
front.

Attach (F) to the lower
joint on the right leg, and
then push it onto the crank
that was attached in Steps
2 and 3 until it snaps into
place. Make sure to
position the newly attached
rod so that it is in front.
Attach (E) to the upper
joint on the left leg, and
then push it onto the
crank that was attached
in Steps 2, 3, and 4 until
it snaps into place. Make
sure to position the
newly attached rod so
that it is in front.

Once you have attached both legs, check to make sure that the rods
attached to the crank are in the order of upper left, lower right, lower left,
and upper right, as seen from the front. If the order is different, the legs
may not move smoothly.

6. Attach the second frame.

7. Attach legs to make three sets.
[3] Putting the body together
1. Attach the two body assemblies together.
Fold the rubber band into two loops, and position it so that
the tops of the frames pass through it.
Attach the second frame
firmly to the first frame, so
as to sandwich the legs that
you put together in Steps 2
to 5. Line up the three
joints on the frames, and
position the slot in the
middle of the frame so that
it snaps into place on the
central axis of the
crankshaft.
2. Insert the shafts (long) into the frames.
3. Attach the stoppers.
Stopper
[4] Attaching the wind turbine
Affix two strips of double-sided tape to
each of the T-shaped ends on the wind
turbine base. Remove the paper on one
side of the double-sided tape and affix
the tape over the protrusions on the
wind turbine base as shown in the
diagram below, but leave the paper on
the up side remaining for now. You
will end up affixing a total of 10 strips
of double-sided tape to the wind
turbine base.
Fold over about 1/3
of the double-sided
tape to make it
easier to remove it
from the paper
backing it comes on.
Double-sided tape
1. Attach the blades.
Remove the paper backing on the up
side of each strip of double-sided
tape, and attach each blade so that
the two holes on each blade line up
with the protrusions on the wind
turbine base. Do the same for all
five blades to attach them.
2. Insert the cogwheel shaft into the body.

3. Attach the cogwheels
After attaching the cogwheel (small) to the crankshaft axis, attach the
cogwheel (large) to the cogwheel shaft and push it in until it snaps into
place.

4. Attach the wind turbine.
Use the shaft (short) to attach the wind turbine to the stopper part on
the top of the frame on the side on which the cogwheels are attached.
Attach the tube (small) to the end of the shaft (short) to keep the wind
turbine in place and prevent it from falling out.

Getting the Mini
Strandbeest to Walk
●Using wind to make it move
●Using the rotating shaft to make it move by hand
You can wave a round paper fan or
a folding fan toward it or use an
electric fan to blow air at it. Once
wind hits it, the Mini Strandbeest
will start walking toward the left
as seen from the side of the wind
turbine.
Use the tube (large) to connect the rotating shaft and flange together.
Remove the wind turbine from the Mini Strandbeest as the weight will
drag it down, and then insert the flange into the crankshaft. When you
turn the rotating shaft, the Mini Strandbeest will start to walk.
Flange
Tube (large)
When you turn the rotating
shaft, the Mini Strandbeest will
walk to the same direction in
which the shaft is being turned.
Be careful not to turn it so hard
that the tube gets too twisted.
Use the remaining parts to make one more assembly just like this.
Repeat Steps 2 to 6 until you
have assembled three pairs of
legs for a total of six legs on
four frames, connected to the
crankshaft. This completes
one half of the body of the
Mini Strandbeest.
Insert the shafts (long) into the holes on the frames shown in the diagram.
Adjust the shafts (long) so that they stick out on either end by a small amount.
After completing these adjustments, pull on each rubber band loop and hook
them around the
ends of the frames.
Attach the right and left sides of the body
together, making sure that the legs are not
positioned in the same way. If the legs are
all positioned the same way, turn the joint
on the crankshaft 180° on one side only.
Tube (small)
Shaft (short) Rotating shaft
There are two extra
strips used as
spares.
* Check to make sure that the legs move
smoothly by turning the crankshaft. If the
legs do not move correctly, go back to Step 5
and check to make sure that the rods are in
the correct order.
* If the frames do not seem to be attached
together properly, make sure that each
frame is firmly attached to the crankshaft.
Turn the cogwheel shaft while
pushing on it to firmly attach
it.
Make sure to leave about 1
to 2 mm of space open
between the tube and the
wind turbine to ensure
that the wind turbine
rotates smoothly.
Attach the two body assemblies together, oriented so that the joints on
the frames and crankshaft face in the same direction. When attaching,
fold the rubber band over into a double loop, and position the loops in
between the joints on the tops of the frames on the assemblies.
Attach stoppers to the protrusions on the frames on either end of the
body (three on each side for a total of six).

Insert the cogwheel shaft into two frames on the body. Once you have
inserted it into the second frame, turn the cogwheel shaft 90° so that it
snaps into place.
