Introduction: Mecatronic Tortoise
Second Prize in the
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
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.
Servo myservo; // criando o objeto servo
int pos = 0; // criando a variável de posição do servo
myservo.attach(2); // Atribui o servo ao pino 2
for(pos = 75; pos < 170; pos += 1) // rotina para mover o pescoço para fora do casco
delay(1000); // pausa de 1 segundo
for(pos = 170; pos>=75; pos-=1) // rotina para mover o pescoço para dentro do casco
We have a be nice policy.
Please be positive and constructive.
