Taking Form — Lukas

IMG_3192

This week has been a week of progress, as components are completed, hardware is acquired, and inspiration is gained.

Last night I saw the movie The Martian. Although it’s kind of riding the wave of space movies like Gravity and Interstellar, it’s still a welcome addition to the trend. In the movie, Matt Damon gets stranded on Mars after an emergency evacuation from a storm (apparently there are storms on Mars) when flying debris separated him from his crew. The movie is jam packed with Matt Damon doing almost believable makeshift science to keep himself alive, as well as a tremendous team-driven effort on Earth to get the astronaut back home. I was inspired by this resourcefulness, the illustrated power of engineering and science, the pursuit of the unknown, and the feeling you get when your dreams come to fruition.

For so long the Grazer has been a figment of my imagination, at most some sad little pieces of aluminum. Finally, however, the true project is coming to life. Whenever I really start to get underway with a project, wether it be a treehouse or a strandbeest, I get a feeling like I’m actually doing something worthwhile. With this comes motivation, and more excitement to get back into the shop and continue working. Moral is high.

This week, I focussed again on figuring out the aluminum triangles. I ended up modeling the first one in Fusion 360, using the Sketch function instead of 3D parts. This kept everything in two dimensions and simplified the whole design process, which was still actually pretty complicated.

triangle layout

Triangle layout, actual axes of rotation are the pink dots and the corner of the triangle, support structure represented by the long rectangles.

This allowed me to measure all the proper angles and lengths to cut. I followed the recipe exactly, and somehow the aluminum version still had gaps in the angle cuts…. not really sure why…IMG_3189

gaps :(

gaps 😦 and rivets waiting to be riveted

I plan on securing the corners with plates and rivets (above), as well drilling screws through the corner into an end of aluminum tube jammed with Delrin (a type of strong machinable plastic polymer). Picture on that pending. The only reason I haven’t yet riveted the rivets and screwed the screws is because I don’t have the right screws, so it’s hard to screw a screw that’s not there.

I also got some cotter pins for my joint axes, and drilled holes to fit into all the joint components. They look like this:

Hopefully by tomorrow the triangle will be put together.

    I absolutely love this project, and I don’t even know what’s going on here! I have, however, seen pictures and videos of some very impressive strandbeests, and they’re quite incredible. I appreciate what they say about science; that it’s not just about practicality and discovery. Math isn’t just about papers and pencils and angles and corners; it’s can be used to create something just as beautiful as any painting. Anyway, a suggestion for the future: as someone who doesn’t understand engineer-speak, some links on what things like plates and rivets do in this context would be extremely helpful. I also wouldn’t mind some hints as to what you want the end goal to look like. I know you know have the whole thing planned, but how big do you intend to make it? How quickly will it move? What is the intended color and shape?

    I’ve been hearing your mill working, while the 3D printer was failing me. Glad to see that you are making consecutive progress. Morals will always be high when money is high. If your final product comes to life, there are many opportunities to make economic values out of it.

    I simply love your project as well as the way you write about it, Lukas! Your idea is absolutely creative and promising, as I think creativity is so important in the future world. Just like what Randy said in his comment, if you can make your idea come to life, I can’t see how it is not going to be economically profitable. Keep up your good work bro!

    Crazy dude, the monster is coming together. I can’t wait to see what you do next, and the whole project coming together. What I like about your study is the physical presence of your drive; it shows how much you put into this.

    Your project has come such a long way from your last blog post. Sorry about the machine difficulties you have been experiencing but your designs look really nice and you have responded to the challenges well. I look forward to seeing how your Grazer comes together.

    Looks good. Kind of funny how the CAD model doesn’t line up with reality. Even errors of a few thousandths, in the model or cutting can add up pretty quick.
