Features

• Total length 197 mm The picture shows the kit assembled.
• Swimming with a Large Tail Fin
• This is an assembly kit for a puffer-shaped robot that swings by moving its tail fin from side to side.
• The fuselage is divided into two parts at the top and bottom, and the motor, gear box, battery box and switch are set at the bottom.
• The rotation of the motor is decelerated by the gear box and transmitted to the tail fin by the crank and link rod.
• The upper part is clear green and the lower part is white parts, so the mechanism can be seen clearly.
• It is assembled by fitting and screwing, and wiring is easy using rubber pipe.
• With gearbox and motor.
• Running time: Approx. 4 hours using alkaline batteries.
• Play while floating on a calm surface without waves.
• The rotation of the motor is reduced by the gearbox, and the rotation motion is changed to the reciprocating motion by the crank and the link, and the tail fin is moved left and right.
• You swim 1 meter leisurely at a speed of about 7 seconds.
• Waterproof tape is applied between the upper and lower parts of the fuselage, and rubber rings are used for each screw hole and switch lever to ensure waterproofing.
• You can adjust the mounting angle of the tail fin by pulling up the stopper on the lower side of the tail fin as shown in the photo.
• Not only can you make him swim straight, but you can also turn to the right and left, and change the angle of turning further.
• The tail fin is made of a soft material, so you can cut it freely into the shape you think.
• Let's make your own original robo! ~ Transforming into a whale and a tadpole ~
• A mecha puffer fish was transformed into a whale and a tadpole.
• The main point of a whale with a large sippo out of the water is to swim slowly while rotating the squirt on its head made of soft plastic wood.
• Tadpoles can also move around on land with pulley hind legs.
• In addition, a tune-up motor is installed to speed up the movement.
• In both cases, the colors of the face and body are elaborated to show individuality.
• You are also challenged to make an original robot!
