The Mechanical Blowfish is Tamiya's first water-based Robocraft series kit. Using a crank and linkage rod system, this robo-fish propels itself through the water with its swinging tail fin. The white underbelly 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 the transparent green back means you can see all the mechanics even after completion.
Tail Movement
Gearbox transfers motor rotation to swinging tail movement via crank and link rod. The gearbox plays a vital role in reducing motor speed and allowing for splash-free movement. It takes about 7 seconds to swim 1 meter.
Water-Proofing
Uses water-proof taping and rubber O-rings to stop water from coming in through screw holes, the power switch, the tail fin, and the joining line between the top and bottom halves.
Swimming Control
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.
