MEA 211 Final Project


I began by following the anatomy of my husky D.D, by creating the body from the neck down I was able to create a robot wolf body that felt proportionate. Using simple blocks for the limbs and a large cylinder I was able to put elements of robotics into the design. The fur used for the wolf is actually an asteroid block that was included within a separate Tinkercad pack.

The head of the wolf was made separate from the body. The bottom of the wolf head has two holes, one meant for a peg to connect the body and wolf, the other to insert the Red LED that will be used for its tongue. The tongue LED will have a pulsating glow, the code for the glow is shown below.

Extra Trivia: The D.O.G on the back of the wolfs collar stands for Demi Organism Guardian

Arduino Code for Fading

int ledPin = 9; // LED connected to digital pin 9

void setup() {
// nothing happens in setup

void loop() {
// fade in from min to max in increments of 10 points:
for (int fadeValue = 0 ; fadeValue <= 255; fadeValue += 10) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 50 milliseconds to see the dimming effect

// fade out from max to min in increments of 20 points:
for (int fadeValue = 255 ; fadeValue >= 0; fadeValue -= 20) {
// sets the value (range from 0 to 255):
analogWrite(ledPin, fadeValue);
// wait for 50 milliseconds to see the dimming effect

Final Project Proposal

Name of Project

Robo Wolf

Description of the Project

A 3D modeled Wolf that will utilize the Arduino LED lights to create a “glow” effect within the mouth of the wolf. The wolf will be mostly natural minus the chest/collar area which will be robotic in design.

Target Audience 

My target audience will most likely be canine lovers and possibly those interested in robots. I hope the glow effect attracts everyone though.

Technologies Used

My project will incorporate Arduino technology, Tinkercad, and a bit of Adobe Illustrate for sketches.

Step-by-step Plan

By using primitives and removal tools in Tinkercad, I’ll sculpt out the wolf head and from then on make a primitive body that I will cover in fur.  The body itself won’t be incredibly detailed, as It will be mostly cubes and cylinders covered in fur to give the appearance of a shaggy wolf pelt. There will be a hollowed-out hole within the mouth of the wolf, within the mouth will be a red LED light that will glow in intervals. The placement of this LED will make it appear to be the tongue of the robot.


Raziel Ortiz 3D Modeling and Printing

What difficulties if any did you have in creating your model?   

The merge feature in Tinkercad threw me for a loop, mostly concerning the deletion of certain areas of the frog. Creating the toes were also a bit of an annoyance as the base of the cones I used stretched in a strange way and had to be deleted with the removal tool.

Is this your first time using a 3D modeling program?

I’ve used Maya and C4D before this class, while not as versatile as C4D, Tinkercad is very useful for bringing out objects and working with primitive shapes.

How did you change your character from the earlier versions?

The character now has a bigger eyeball and a thick outline for an eyelid. The rounded handle on the back of the frog became a hollowed-out rectangle and the face of the frog is more rounded down.
