Mecatronic Tortoise

Hi This time I will show you how I did the Tortoise. It was easier to be done because it has a simple movement to collect and stretch the neck.

This was an animal I made for the presentation of my daughter because it also represents one of the most smuggled animals and also suffer a lot of abuse. When buying one of these, make sure you know where the animal originated. Otherwise you probably will be financing and encouraging the smuggling of wild animals.

Step 1: Materials:

- Figure of the Tortoise (free): http://www.yamaha-motor.co.jp/global/entertainment/papercraft/animal-global/yellowfooted/

- 8 sheets of A4 paper (the file is only two but I need to print in poster format, 4 pages per sheet for the sea turtle is a little bigger)

- Two wooden clothes pins

- Pieces of balsa wood * 3mm (Ferry because he had used but can be used cardboard 0.5 mm)

- A Styrofoam tray (those which are the slices of cheese on the market)

- A servomotor with a plastic coat hanger

- Two bolts with nuts and washers (of about 6 cm)

- A strip of  velcro (6 x 3cm)

- Programed Arduino, brotoboard, wires, batteries, servo lead Connection

- Glue, hot glue, instant glue, scissors, ruler, pliers, etc ...

Step 2: Assembling the Parts of the Tortoise

Paste the 8 leaves, cut, assemble the parts isegundo the order described below.

Paste the following pieces and book:

- 1.2 and 3

- 5:07

- 6:08

- 9

- 10

- 11

- 12

Note: no need to use the part number 4

Step 3: Mounting Base

Disassemble the clothe pegs and reserve one of the springs. The raccoon pieces of wood are the "bones" of the legs. I used a piece of foam board to put on your feet and glued with hot glue, the wood on them. Using the part number 8 ("belly"), measured the distance that would be one of the other leg and glued a piece of wood connecting them. Then measure the distance between the front and back legs, I cut and pasted the wood core, uniting all fours, forming the base.

Step 4: Putting the Servomotor and the Lever

I support and screwed the servomotor and then, with speed glue, pasted that amount in the "spine" of the tortoise. I made a rod-shaped handle that was used to transmit the motion of the servomotor to the head of the turtle. I called the stem to the crosshead of the servant with the aid of a spring clothespins that has been stretched with the help of pliers.

Dai, just paste the head of the tortoise at the tip.

Step 5: Final Assembly

The piece Nº 8 was glued down and pasted a few pieces of velcro on the hull and the legs of the tortoise, if there was a need for some maintenance. Dai, was enough to fit the hull.

Note: The lower hull is beginning to appear in the original file size.

Software:

#include <Servo.h>

Servo myservo; // criando o objeto servo
int pos = 0; // criando a variável de posição do servo

void setup()
{
myservo.attach(2); // Atribui o servo ao pino 2
}

void loop()
{

for(pos = 75; pos < 170; pos += 1) // rotina para mover o pescoço para fora do casco
{
jabuti.write(pos);
delay(15);
}
delay(1000); // pausa de 1 segundo
for(pos = 170; pos>=75; pos-=1) // rotina para mover o pescoço para dentro do casco
{
jabuti.write(pos);
delay(15);
}
}
