Run Ralphie Run: A Mechanical Buffalo (Final Report Part 2)

April 25, 2016

Final Report Main Project 2016, Student Work

How did it turn out? Overall, I’m pretty ecstatic with how this project turned out. Amazingly, my scope and vision turned out to be nearly identical to my initial idea and conceptual design. However, the way that I executed that vision (internal components) turned out to be quite a challenge and rather unexpected. I ended up…

Final Report Main Project 2016, Student Work

Run Ralphie Run – What is it? Run Ralphie Run, otherwise known as the ‘Mechanical Buffalo,’ is an automata toy made from the Colorado Buffaloes logo. This automata is actuated with a small peg that rotates 30 degrees and causes the legs to move. Then, the peg is rotated 30 degrees in the opposite direction…

Update Weds April 13 2016

Ralphie IV lives!!!!! *MIC DROP* *** Ralphie V is currently printing. In real life, the current Colorado Buffalo is Ralphie V. Therefore, this is the final design iteration :). I have made some minor adjustments to improve the toy’s ability to be assembled. As you can see, I’ve added arrows to depict the correct orientation…

After a lot of work and frustration, this project is REALLY close to being finished! *** Ralphie III In order to get the four-legged, hooved animal gait mentioned in my last update, I decided to use a gear train on Ralphie III. After selection locations for the three gears, I placed circles at each gear and…

Progress: Ralphie II works well, though I accidentally broke off a small piece of it and replaced it with a bit of tape. Here’s a small animation: Buffalo Snail! Problems: Progress on Ralphie III is going much slower than expected. I have decided that I want the buffalo’s legs to move in a somewhat natural gait.…

“Ralphie I” was just a simple snap fit box. See: http://www.thingiverse.com/thing:1384028 “Ralphie II” is a snap fit box with four movable legs. “Ralphie III” will integrate the mechanism that moves the legs. The internal ends of each leg will be modified to incorporate this mechanism. *** Solidworks Ralphie II: Printed Ralphie II: Gold PLA print at…

Mechanical Buffalo – Top 5 Constraints

Student Work, Top 5 Constraints 2016, ZZ 2016

3D-printing only (DIY kit for Thingiverse) No fasteners (all parts must align or lock together without fasteners) Print Time (2-4 hours per prototype, so I can only cycle through a couple of iterations per day) Material properties (must make design considerations based on one type of filament – eg: a snapfit feature designed for PLA may not work for ABS due to…

Mechanical Buffalo – Conceptual Design

Main Project Design Review 2016, Student Work

After considering several possible ideas for dynamic, fully 3D-printed toys, including things like transformers figurines and twisty puzzles, I have settled on creating a mechanical buffalo crank toy. The buffalo will have moving legs, at minimum, that will be actuated by a crank to make it appear to be running. I will ultimately create a printable kit with…

3D-Printed Transformer/Puzzle Inspirations

Main Project Inspirations 2016, Student Work

Basically, I want to make a completely 3D-printed toy (for children or the young at heart!) that is capable of transforming from one configuration into another through simple manipulation (twist, push, pull, etc). The most difficult aspect of the project will be designing the snap-fit/sliding/rotating features that allow the transformation to occur. This will surely require lots of test prints,…

Aspirations 2016

This semester, especially with my final project in this class, I want to hone my skills as a CAD/mechanical designer and 3D-printing enthusiast to make a popular, if not featured, 3D-printed assembly on ‘Thingiverse.’ I started getting into Thingiverse a little bit last summer and a few people have noticed my work, but it would…

Student Work, Upcycle Project Report 2016, ZZ 2016

For my upcycling piece, I chose to make an abstract wireframe sculpture. For the body of the structure, I solely used straightened paperclips and rubber bands. The feet are made of Play-Doh. Inspiration The initial inspiration for the project was the idea of creating something using simple, repetitive tasks. My mind tends to race, so…

…But it was quite painstaking to make. It’s been more about the process than the result so far. When my mind is racing, which happens fairly often, I take comfort in doing repetitive activities. Sometimes, that can be as simple as chewing sunflower seeds or tossing a tennis ball in the air. In this case, it was…

“Retro” architecture

Aesthetic Explorations

In modern architecture, the retro-style appears when brand new buildings are built with the same features (brick facades, roof materials, etc.) as the older buildings that surround them. The time difference between the new and old buildings is often nearly a century. This aesthetic instills a sense of oneness/homogeneity and nostalgia to the region in which it is applied. Modern baseball stadiums…
