Getting Settled at ESA

June 12, 2017spetku0 Comments

It’s Sunday night. There are just a couple more hours left before I go to sleep and my second week at ESA begins… In spite of it being nearly 10:00pm, the sun is still above the horizon shredding gold through the clouds here and there, and even making this killer rainbow chunk. Last Sunday, I arrived in Holland. It felt like I was tied to an unstoppable force being propelled through uncertainty towards a heap of even more unknowns… which was exciting or terrifying or equal parts both. Once I made it safely to the *penthouse* I’ve been taking roost in (its on the top floor of the tallest building around, at 3 stories. perfect nest), I began mentally preparing myself for what was to come. During the four days of my first week at ESA, I’ve had a good share of wonderful conversations with people who have had many…

How Could a Robot Taste Things?

May 5, 2017spetku2 Comments

THE TASTING (SAMPLING) FOOT I was giving a talk at Hackaday’s SuperCon last Fall that actually had the term, “Tasting Feet” in the title. Because of this, I at some point found myself in a conversation with some other makers about whether or not my mechanical wonder feet actually did in fact “taste”, as I claimed. So sadly, I could only really conclude after some thought that they did not. (not that any robot can taste things quite like a human in the first place) After admitting that my creations didn’t actually do what I enjoyed bragging about, there was some talk about how I could simulate the act of ‘tasting’ more effectively. Almost immediately, the idea of using litmus paper came up, and I think it has sat on the immediate back burner of my mind ever since. This past week… I finally made what I can comfortably call,…

Noodle is Gettin’ Bean Feet!

April 21, 2017spetku3 Comments

Four Flavors of Tasting Feet This summer, I am once again diving into designing mechanical personality quirks. I’ll be investigating new and exciting ways for my robot, NoodleFeet to interact with the world. This time, my focus is the wet, tingly and preferential aspect of TASTE. From now until the end of August, my goal is to produce four different tasting modules that each demonstrate some aspect of sampling or preference. You could think of them as the “four tasters of the apocalypse”… The project parameters are that each module must fit within a 3” x 9” cylindrical space (i.e. the size of Noodle’s foot appendage). For reference, the mechanical goodies I am to design must be housed inside one of these frames: Bean Planting The first Module that I chose to focus on will effectively plant a single bean a few inches below the surface it stands on. Why beans, you ask? Well,…

Noodle Puberty

October 5, 2016spetku0 Comments

Sometime in April, Noodle started to change. He stopped hiding in his blankets and began spending his nights surfing through hardware catalogues alone in the darkness. He became curious about linkages, pivot joints, self lubricating thrust bearings and among other things, the prospect of being made of something harder. Noodle started dreaming of becoming metal. As I mentioned in my previous post, just as I was about to tackle the conundrum of mechanical drooling… I went to JPL this June and met the mechanism that inspired Noodle’s gripping toes in person: The LEMUR probe has easily a billion toes… all agile, long and barbed. You know by looking at them, that if it reaches for you, you aren’t getting away. I returned home feeling a tad inadequate. Noodle’s current apparatus with its 8 lonely toes did in fact look pretty sparse. In the period of a weekend I managed to tweak my…

Tasting Feet : Gripping and Licking

September 29, 2016spetku0 Comments

In case this is your first time hearing about the project, I’d like to introduce you to the heir of all lint and space rocks, NoodleFeet: Like his name suggests, Noodle is a “feet-based” mechanical life form who has been designed to taste objects (among many other things). Though Noodle has lofty aspirations for world domination, he is still a fledgling one-year-old… and his mommy (me) needs to work on equipping him with all the space exploration and world conquering super goodies he’ll need while on his journey. For that, he is in a state of perpetual growth. My challenge to myself : I decree, each of Noodle’s robot feet must be able to grip onto surfaces with many small cherry-red toes so that a long central silicone tongue can dart forth and taste surfaces while expelling frothy wetness from a reservoir within. All three mechanical systems must work consistently, and fit collectively in the same 4″ x…

Carl el Robo Flamingo

Assembling Carl the Flamingo

February 8, 2016spetku9 Comments

Sticking out from my toaster’s head like a crude antenna, is a classic lawn ornament, the flamingo I’ve come to call Carl. Unlike most of the other residents in the lab, he is not an electronic or robotic thing. It has been my intention since I brought him home last September, to liberate Carl from his static form to join the ranks with his mechanical compadres: Carl’s fate is to become a ball-balancing robot… one with motors and wheels… that can balance… on a ball. If you’ve ever seen one, ball balancing robots are impressive as hell and fascinating to watch… because you almost can’t believe that they could work as well as they do! I mean, heck… I can’t even balance on the floor sometimes. The first thing I learned upon researching these beasts, is that in order to build one of my own… I was going to need to locate some “omni” wheels to…

Noodle’s Gripping Toes

December 6, 2015spetku5 Comments

For the past year, the four tawny stalks that NoodleFeet balances upon have remained common pool floaties, 2.5 inches in diameter, hollow, providing nothing more than the obvious support needed to function as legs… but Noodle longs for something greater. GRIPPING TOES When Noodle feels threatened, there is little he can do to defend himself. He can beep and perhaps canter away at a slow speed… but he is passive and therefore vulnerable. He isn’t equipped to handle the harrowing task of world domination::cough:: I mean, daily life. To fix this, I decided to add another layer of complexity to Noodle’s most important characteristic: RETRACTABLE GRIPPING TOES for his feet. A while back, I came across a video of a rock drilling probe concept by JPL. This neat claw attaches itself to a surface by splaying out a hundred or so mini grappling hooks in all directions, which catch on the rock and help anchor the central…

A Creeper with a Beeper

November 30, 2015spetku0 Comments

There comes a time when it is more important to pour hours into your offspring’s Halloween costume than your own. This was the year that happened to me. As it was Noodle’s first Halloween, I decided to make him into a huggable creeper from Minecraft… so he could steal all the hearts with his cuddly adorableness. I spent over a week hand sewing this little number together from soft fluffy fleece. It was surpassingly time-consuming to make each of the four cubic creeper feet booties that slipped snuggly over Noodle’s noodles. I designed them with clearance slots so they wouldn’t obstruct his ability to move. Noodle was the happiest… 😉 I took him out a little during the weekend to make sure he got proper exposure… but wasn’t quite ready to actually let him try to trick-or-treat on the street. His creeper feet were so wide that he was more or less safe from falling…

The Walking Noodle

October 24, 2015spetku4 Comments

NoodleFeet finally took his first few wobbly steps a couple of weeks ago. I’m so happy to have finally wrapped my head around a walk cycle that works in spite of his obvious physical limitations; wobbly joints, weak motors, and top-heaviness. Now that this milestone has been reached, he can no longer remain in his weak proto-form any longer. Noodle must grow to become the powerful little leg-hugging monster he was always destined to be. PHASE 2 BEGINS!!! The most important upgrade I needed to make was to his brain. A custom PCB would replace the current Arduino and allow Noodle all of the other behaviors and abilities he would like to have, such as beeping, balancing, and of course… actually seeing! With help, I tossed together a fully loaded board sporting an ATMEGA328 that houses the potential for all of those systems, and will also connect to a Raspberry Pi when I’m ready to dip my…

Eye of Toast

September 8, 2015spetku4 Comments

I would like you to meet my toaster. The toaster is an old character of mine who has survived through subtle reference in the things I draw and build. Nothing I make is about the toaster, but the toaster is about everything I make. He’s my chrome totem. While I was in college abroad, I bought an actual physical model from the early 30s off eBay which looked pretty much identical to the one from my doodles (still works too!). I had big plans for this little toaster, but at some point we got separated during my move back to Las Vegas. The toaster got packed in one of my friend’s moving boxes and it wasn’t until this summer that we finally remembered to unearth him for me to take home. After three years of waiting, toaster is now happily sitting next to me on my bench… It’s wonderful to be reunited, but admittedly it feels weird talking to him during the…
