noodleFeet : Goes Metal

February 8, 2015spetku0 Comments

I’ve relied on 3D printing for so many of my prototypes lately, and have finally come to a point where plastic won’t cut it any longer. I require metal, in this case aluminum. The likes of which I ordered from McMaster-Carr and received in the mail last week. I literally spent the majority of the weekend meditating over how to measure my cuts and holes… as for the first time in a long time, their accuracy and placement was entirely up to me and my calipers, not some Cartesian goo plotter as I’m so spoiled by… While everyone was downing beer and watching the Stuperbowl, I was in the garage with Mark playing with his father’s ancient drill press. He eyeballed one axis, I checked it against the other, and we were able to punch the 24 holes needed on the four pieces of aluminum tubing which would soon be noodleFeet’s strong new legs. As…

noodleFeet : Proof of Concept

January 27, 2015spetku0 Comments

Last week I started building a new robot who I’m calling noodleFeet! He is essentially a spider-type walker who will locate nearby legs, approach and then lean on them. In addition to having that specific purpose, he needs to look a particular way. I’ve been drawing him in the margin of my notes for weeks now, so he’s become something of a character to me: In order to make a robot that does these things, I need to design the mechanism itself and how it will be attached to the motors driving the motion (challenging and fun). At the same time I need to learn about Open CV and figure out how to make a computer recognize all the different shapes that legs come in. This will involve a camera and some coding (hard and not fun). With these two elements combined, I’ll eventually end up with a leg hugger…… or leaner. I’ll talk about the details of those steps when…

mechaFeet : Prototyping with Algodoo

December 13, 2014spetku6 Comments

I had to wait this week for the sensors I ordered to come in the mail before I continued progress on Jelly. With Jelly on hold, I couldn’t save myself from starting on yet another project idea I’ve had fermenting in my mind for a while now. It involves building a pair of mechanical chicken (or raptor) legs that can stride in sync with one another; both legs driven by the same moving part. The thing that initially inspired me to make a mechaChicken was this quirky and utterly gorgeous mechanical hand ostrich thing by Tim Lewis called “Pony” (that and all the stupid bipedal robotic dinosaurs that are in the stores for Christmas this season). My problem is that I don’t have a whole lot of experience with big kid mechanical motion, so it took a lot of meditating on before I even got started. Two nights ago, I laid in bed and…

My New jellyBot Prototype, Racky

October 12, 2014spetku0 Comments

About a year ago I started building a robotic jellyfish inspired by Festo’s submergible AquaJelly. I was just beginning to figure out how to get the thing moving when I got sidetracked with the prospect of launching a Kickstarter campaign and dropped the project cold. During this whole long year while I’ve been fulfilling the said Kickstarter, this poor jelly prototype (“Boney”) has watched silently from a distant shelf in the workroom, begging me to pick it up again. Finally this weekend I was able to spend some time giving the old parts a makeover… in yellow. I added a nice gentle curve to the moving pieces, taking after the design of its cousins, the delta robots : Last year I decided to use a rack and pinion to get the parts to move in leu of Festo’s fancy linear actuator that they showcase in their model. Never having used, let alone designed a working rack…

Robot Army : Shipping at Last

September 15, 2014spetku0 Comments

Much to my dismay… I woke up last week to find that it was September. While I struggle to remember where the summer went, I think I’ll make myself a cup of chai and recap whats been going on in the past month or so. The most exciting thing to take place was our dry run at SYN Shop. We invited a small number of people who preordered kits back in February to be the first to pick up their newly adopted robots in exchange for testing out our instructions. Everything went smoothy, however I’m still sitting here editing the instructions… and I’m tired of looking at them. ::shakes fist:: As much as I thought I had boiled down the steps… I need to expand several of them out even more to make absolute sure that people can’t skip or misread them. It’s taxing >.< I definitely need to do a…

Robot Army : Production Mode + Lime Light

June 18, 2014spetku5 Comments

Mark and I are FACTORY Now that the hype and excitement of Maker Faire has passed, we’ve buckled down and gone headlong into Fulfillment mode. Last week we started bagging things, like steel balls and hardware : The acrylic base pieces are in a cue to be fabricated, and our Rev. E brain boards will be sent in sometime this week once we verify that these- yes THESE are the final rendition to be included in the kit. Our friend Andrew from SYN Shop is also helping us mass produce our parts on his fleet of 3D printers. The production of the robot parts is what will potentially push shipment back the most. Luckily though, Andrew also taught us how to make use of our second extruder so that we can print the same amount of parts in half the time. Since we’re getting twice as many parts in a day as we…

Robot Army : Maker Faire

May 22, 2014spetku0 Comments

Mark and I rolled into Vegas yesterday right before the sun started to bow out of the sky. We stopped at Chipotle and picked up some over-stuffed puppy bags to push into our faces with beer upon finally returning to the house we left in pieces a week earlier. It felt like we had survived the apocalypse. After that ice-cold Carona we untethered everything from the clump in the back of Mark’s Kia and began dragging things into the house where they belonged. Once all three pallets of robots made it onto the table we both collapsed on the couch and giggled in delirious exhaustion. Maker Faire was exactly like it was last year; bursting with stimuli. The visuals were nonstop, even being trapped in our booth the whole time… which was right next to the bleeding stage Arc Attack performs on. I don’t care for tesla coils. They’re cool, but I don’t…

Ok, ok… I’m done lamenting about the late nights. They work… I’m happy. Time for a beer and some heavy hype building. Share this with your friends and stop by our booth at Maker Faire if you plan to be there. =] Robot Army FTW

Fifth Element Mood Stones

Elemental Mood Lighting : Just Add Love

April 28, 2014spetku7 Comments

We probably shouldn’t have taken on this side project amidst all the pressure to prepare on time for our display at Maker Faire, however I’m glad we have this awesome life relic to show for it! Since my last update, I took the four complete 3D printed stones and gave their surface a rather sharp makeover. All those years in art school came in handy again. It surprises me just how many techies have never heard of gesso … so I’m tapping this apparent art secret for the sake of painting on an otherwise stubborn surface. ABS will take acrylic paint, however instead of priming it with anything you might get from Home Depot in the paint section… you can go to Blick and grab a pint of clear gesso (canvas primer). It may be a little more expensive, but it’s less volatile, doesn’t have any fumes, and has the best tooth when…

Robot Army : Las Vegas Mini Maker Faire

April 8, 2014spetku0 Comments

I started composing an update a week ago… and never finished it. Now Mini Maker Faire is over. Oh well. In any case… back then everything felt like it was falling apart. I wrote venting about how terrified, annoyed and disappointed I was that things wouldn’t just go the way they were suppose to. As we encountered one complication after another, each bump yielded an even better solution than what we were originally planning. Long story short, all is going great again. Better in fact. We had an excellent Mini Maker Faire on Saturday. All of our friends and local backers came to see our kids perform and talk to us about our maniacal future schemes. Though we brought a soldering station and work lamp just in case an all systems failure occurred… nothing went wrong. Everything just worked…. the whole time (aside from the stupid Processing app crashing every now and…
