If the tail fins have been previously assembled, please go directly to the Instructions on the next page.
Tail Fin Assembly
From the Bionics Kit, locate the bag containing the tools and 2 screws (used in Step 3). Next, locate the bags
containing the small screws and nuts (long and short) and the plastic support pieces (large and small).
To assemble the large tail fin, attach the large support pieces to the inside of the fin using the longer screws, nuts,
and tools.
Locate the plastic component (with cutouts). Place the opening on the base of the assembled large tail fin over the
post on the plastic component. Align the screw holes and connect the pieces together using the 2 screws and a
screwdriver.
Assemble the small fins using the small support pieces, the shorter
screws, nuts, and tools.

Required items: clear tube
Attach the clear tube to the opening of the large tail fin. The top of the clear tube should
be at approximately the same level as the third support piece from the bottom of the fin.
If needed, cut the tube with scissors to the appropriate length.
Required items: small, waterproof servo motor
Attach the waterproof servo motor to the holder on the large tail fin, such that the rudder
horn of the motor points downwards. Guide the cable of the servo motor through the
clear tube.

Required items: 1 cable tie
While holding the clear tube against the servo motor, connect it to the large tail fin with a
cable tie. Shorten the cable tie, if necessary.

Required items: 4 cable ties
Connect the large tail fin to the rudder horns of the servo motor using 2 cable ties. Pull
the cable ties through the two small tabs of the fin and then through the openings of the
rudder horn in a crisscross fashion. The two cable ties cross above the fin. Add 2 more
cable ties to act as stopper.
Testing
Carefully move the rudder horn back and forth with your finger to check the tension of the
cable ties. If the fin does not move evenly, the length or the tension of the cable ties may
have to be corrected.

Shorten the cable ties, if
necessary.

Required items: transparent corpus (body)
Insert the electronics board with microcontroller into the transparent corpus (body) and
slide it into the rail located inside. Turn the switch “on”. The small light on the electronics
board turns on.
Required items: tail fin (large)
Attach the connecting element onto the transparent corpus (body). Twist to lock it into
place.

Required items: 2 tail fins (small), 1 cable tie
Attach the two small tail fins around the transparent corpus (body) using a long cable tie.
Pass the cable tie through the openings located on the tail fins and also on the corpus
(body).
The two small tail fins serve as lateral fins.
Shorten the cable tie, if necessary

Required items: material for fin
Review some of the basic tail fins shapes found in the Biological Background section on
the bionics4education website. Draw your desired fin shape on the material and cut it
out. Then make two small holes in the fin so that it can be attached to the large tail fin.

Required items: 1 cable tie
Attach your fin to the small end of the tail fin (large) using a cable tie. Shorten the cable
tie, if necessary.
Optional: make a body for your bionic fish
Would you like to add a body to your robotic fish? Simply print the body template
available in the Downloads section on the bionics4education website and then - trace it,
cut it, and attach it!
