Mechanical Blowfish - Tail Fin Swimming Action
Item #71114

The Mechanical Blowfish. Using a crank and linkage rod system
this robo-fish propels itself through the water by its swinging
tail fin. White under-belly holds the motor, gearbox, battery box
and switch and is sealed water-proof tight. Parts are easily put
together by snap-lock pieces or screws, and transparent green
back means you can see all the mechanics even after completion.

Gearbox transfers motor rotation to swinging tail movement via
crank and link rod. The gearbox plays the vital role of reducing
motor speed, allowing for splash free movement. Takes about 7
seconds to swim 1 meter.

Uses water proof taping and rubber O-rings to stop water coming
in through screw holes, power switch, tail fin and joining line
between top and bottom halves.

Pull the stopper located at the base of the tail and turn left or
right to control the swimming direction. The more you turn the
stopper the greater the change in swimming angle. The tail is
also made from an easy to cut material, allowing you to freely
shape the tail for best swimming performance.
