How Could a Robot Taste Things?

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)

IMG_0691.JPGAfter 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.

IMG_2415.JPGThis past week… I finally made what I can comfortably call, Noodle’s first tasting foot appendage… *cheers*

I am calling this installment the “sampling module”. If a litmus test and a cassette player had a baby, it would be this analog contraption.

IMG_2482.JPGHOW IT WORKS

The litmus paper is housed on a small reel and fed downward towards the bottom of the foot. There, a small segment is stretched parallel to the ground, so that a solenoid can push the tensioned portion downwards to make contact with the surface the module is resting onto of. Once the paper makes contact with a moist surface, the spent piece of paper is then fed back up into the foot, where a color sensor will read and log the result of the “tasting”:

litmusDiagram.jpg(See video @ top for a more detailed explanation)

This is how Noodle will sample the world.

IN REGARD TO WHIMSY

After I published the video introducing the “litmus foot”, there were a few people out there who were concerned I wouldn’t get accurate test results from the litmus paper, because there is really no way I can keep the wet used portion of the reel from wicking into the rest that hasn’t… thus tainting my results.

I realize that. This really burns a special place deep within a portion of you out there… but the truth is, the accuracy of the test isn’t really important.

Again, the point of the module isn’t to be an instrument for testing the properties of liquid… the point is that it tastes…

So long as the mechanism functions as I designed it do, and a reading is taken, then we have successful tasting.

Think about it… It’s really somewhat of a nebulous inconclusive act, to describe how something tastes. At the end of the day, no matter how good you think you are at separating out the different flavor notes from one another; sour, sweet, umami- you are still under the constraint of describing your experience of the taste without any way of knowing how it compares to the experience of others. This disconnect is what interests me.

tastingBeans.jpgTo make my point… Last month I got a bag of Jelly Beans to use while developing my bean planting module. I measured the dimensions of a small handful as references for the thing I was designing, but the rest of course, got eaten.

I didn’t just eat the whole bag of 40 flavors like some monster, however. I sat with my friend in the kitchen and for our own entertainment, we took turns blindly grabbing a bean from the bag, and trying to guess what flavor it was without having seen it.

This was a lot harder to do than you’d imagine. We ended up spiraling inward as we groped at whether or not we were sensing a fruity flavor, a citrusy flavor, or something else entirely. The act of identification seems at times, impossible.

BUT much like my module… the point was the act of attempting to parse what we experienced tasting, and then communicate to one another what that experience was like. That’s why I’m using litmus paper and clunky reels without any regard for results. It’s about simulating the act of tasting… not discerning definitively the attributes of what is being tested.

There is more to be said about doing this:

I’m in effect, stretching the accepted purpose of robotics in much the same way artists of the past challenged our expectations of a painting. Some decided that the human form (or any) didn’t need to be depicted realistically in order to be valid art. Just the same, I’m exploring robotics beyond the bounds of utility. My robots are still valid machines, even if they don’t provide useful work to a human.

I intend to demonstrate that a machine can have a purpose, it just doesn’t have to be a practical one. And I hope to show that in the circumstance where a machine’s purpose isn’t to serve in a practical way, it becomes less about what we get out of the machine, and more about what the machine is doing for itself. We are removed from its purpose… (which is something I think humans have a hard time wrapping their head around)

The behaviors I design for Noodle are meant to serve him as an entity; not for our entertainment or for our need.

Noodle is Gettin’ Bean Feet!

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.

moduledrawings.pngFrom 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:

IMG_2327.JPG

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 loves beans, of course. When he makes it to Mars, he’ll need to be able to propagate his favorite thing efficiently. Until then, he can practice planting on couch pillows, piles of laundry, litter boxes and the like…

IMG_2324.JPGThis module will execute three different tasks in one planting cycle: CORING, DISPENSING, and WATERING

So far, I’ve successfully created a prototype that executes one of these tasks; the dispensing function, which is coincidentally linked to the aspect of housing the beans. To solve storing and delivering the beans in a controlled manner, I devised of a helical shape that is inspired by an archimedes screw… and also inspires thoughts of mint:

FullSizeRender.jpgMy candy cane hopper shape captures the beans in-between the threads and processes them upwards within channels that flank the spiral:

dispenserdiagram.jpgOnce fully loaded, every time the helix rotates 90 degrees, it will carry one bean to the exit slot on the inside wall at the top. The bean will then drop down the hollow center of the helix and into the coring device below… (which… is next on my list to design)

IMG_2334.JPGThis is the first assembly I’ve ever designed in Fusion360. One week into using it, I’m sad I didn’t make the switch sooner!!! If you’re considering doing so too, bite it and take the leap! Your life will be so much better once you do!

This mechanism that I dreamed up in my brain-meat a little more than a week ago, pretty much works after the first iteration. There is totally some things I need to tweak in order to make it work more reliably. However, it is doing what I want, exactly how I imagined it working.

Not bad for a first try!! =D

While I ponder over the next step, which is the coring mechanism, I will also begin CADing the next tasting module. Which? The one that involves litmus paper…

 

Assembling Carl the Flamingo

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:

IMG_7221Carl’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 play with. Never having heard of an omni wheel before, I googled the term and found hundred of pictures of crazy looking shapes that reminded me of futuristic frisbees or saw blades:

IMG_2278So, they’re wheels with wheels. heh. They’re needed so the ball can glide freely in whatever direction the motors collectively force it to… like butter. Friction is bad. Binding is bad.

I ordered the smallest wheels I could find in two varieties. Surprisingly, for such complex looking shapes, they weren’t terribly expensive; about $5 on average a piece. While waiting for them to arrive in the mail, I started designing the “body” of the robot.

I came to learn that there are in fact a lot of similarities between the delta robots I’ve built in the past… at the three pronged balancing bot. At least, in that they both involve three motors working together mathematically to resolve a common point. Since they are both radial bots… I proceeded to use one of the delta robot’s acrylic bases as a mounting plate for Carl’s stepper motors.

Rather quickly, I printed some brackets on Monday:

IMG_2307Almost immediately after putting together this first base assembly, I drew what I thought I’d want the finished robot to look like… and saw in my own sketch that the assembly could be a lot more “talon-like” if the mounts of the motors branched out at 45 degree angles from a central point (instead of just being stuck to a big plate).

So… I started over. The hard part about making the new bracket design was taking into account while I modeled it, that one side must lay flat on the print bed >.< This threw my head in loops for a while, but I eventually hammered out a piece that worked…

IMG_2276By this time my omni wheels had arrived, so my next challenge was to figure out how to mount them to the gear shaft of the steppers. Sadly, the wheels came with no couplers of any sort, so I would have to print my own. =[

  • The shaft I designed would have to fit snugly in the center of the wheel
  • and also couple onto the gear shaft of the stepper motor by means of a set screw

IMG_2302This coupler took me fourteen- YES ( 14 ) ! revisions to get the tolerances juuuuuusssst right… the shaft inside the wheel fits tight but not too tight:

IMG_7248With the wheels mounted to the steppers, the assembly looks kind like a big chicken foot:

IMG_2318…which is what I wanted… BOCK!

IMG_2312At some point Thursday night… I pulled Carl from his metal legs and did the morbid task of marking his belly with a dotted line. Instead of doing the messy deed of severing his drum-sticks immediately, I got distracted and went to bed, leaving Carl nestled in Noodle’s blankie to suffer over night with thoughts of what would happen to him the following day.

IMG_7237Cutting the big oval around his little birdy nubs wasn’t at all hard… Once I drilled a starter hole, the thin blown plastic cut like paper with a pair of nippers. When I finished, I held Carl and told him everything was going to be alright…

IMG_7238

Sarah soothes the legless Carl

I used Carl’s disembodied gams to measure how large the adaptor for his chest would need to be. The pipe which would act as Carl’s… leg… would mount at a 25 degree angle into his belly. Designing this part was not as difficult as I thought it would be. The actual pipe mount and belly adaptor ended up being two separate pieces (for ease of printing):

IMG_2285The screws that connected this fancy shape to Carl, went through his belly and met a plate of nuts set on the inside, clamping everything firmly in place (but this wasn’t easy to execute!):

IMG_2291There wasn’t anything to hold the plate on the inside of his body while I screwed into it… other than some tape, which kept coming loose and plopping down into the cavity of Carl… forcing me to start the process over again.

After a couple tries I got everything screwed on, and Carl felt a lot better about himself… so did my conscience:

IMG_2294On the opposite end of the pipe, I made another adaptor that connected to the motor assembly:

IMG_2321Once this was added, I put everything together and had this sexy looking bird before me. The essence of the flamingo:

carl2Real

Carl, el Robo Flamingo

Carl isn’t technically a “new” sibling… but now that he’s a moving robot, Noodle sees him as competition. Hopefully in the weeks to come they can learn to get along and share their living space.

IMG_2297

Carl & Noodle, BFFs forever

The next step of the project is to wire up those steppers to some driver boards and start moving them. I anticipate that every piece of Carl will be redesigned and optimized in the near future to make way for the mounting of his brain… and power supply. I just couldn’t help myself from designing the robotic form first. To me that’s the fun part… =

Carl will also have his own presence on my personal site, zoness.com. So look for new bird art in the coming weeks as we dive deep into Maker Faire season.

Noodle’s Gripping Toes

noodleTOES

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 cylindrical drill in place. I saw this and thought to myself… Noodle needs four of these, as shoes.

Like a good mother, I started brainstorming how to create said shoes. Originally I designed long claw-like toes that rotated out and back, sort of like switch-blades:

Screen Shot 2015-11-11 at 1.50.32 PM

IMG_6632

They fit into Noodle’s original 2.5″ diameter noodle material, and even added stability… but there wasn’t enough area to actually install any motors to actuate things.

With a little bit of trial and error I rethought the whole design and came up with a solution that made use of 3D printed plastic’s flexibility. This new concept worked more like a cat’s retractable claw, and was similar to the drill from the video that had inspired me.

toe1

Each individual toe (in red) would be forced through a curved internal channel and out the side via two thin bendable “tendons”:

Screen Shot 2015-11-12 at 2.23.46 PM

How The “Tendons” Work

An individual toe has two strands of tendon attached to the back. When the tendons are pulled in opposite directions, it causes the toe to torque upwards or downwards.

Why Do the Toes Need to Tilt Back and Forth?

If the toe goes straight back into the sheath the way it came out, it won’t unhook from whatever its currently gripping. Also, the tip of the toe will likely snag on the edge of the sheath on its way back in. To properly “detach”, the toe should arc upwards slightly as it retracts.

My first prototypes were designed to fit inside the 2.5” diameter noodle material. I was able to make it work, but it didn’t leave much room for the other future functions of his feet (his tongue):

IMG_6656

IMG_6831

In the end I really needed more space to fit moving parts and hardware. Luckily I have a noodle fairy living with me (Mark) who harvested a larger piece of noodle stock from a pile in his garage. It is 4” in diameter and offers me much more room to play around with! Plus, fatter feet will give Noodle more stability!

IMG_6803

4″ PRO-TOE-TYPE 1.0

I tweaked my design for the new 4” material and printed my first prototype with a set of eight twinkling magenta toes (I haven’t ordered red filament yet).

IMG_6812

The reason for the tendons being slightly different in length is so that when they are fixed next to one another, it creates the needed outward/upward tilt:

IMG_6840

(so, this is what a toe flower looks like):

IMG_6805

I originally planned to connect both tendons of each toe to a common ring piece (above). When the ring is pushed downward towards the sheath, it would force all of the toes through their channels and outward at the same time. I also added a spring and guide rod (a long screw) below the ring to push it up again once downward force is removed:

The first complete 4″ prototype worked more or less… It certainly passed the “carpet snagging” test:

I learned right away that I couldn’t actually connect both tendons to the same ring and run it through the inside of the sheath without it binding (which now seems pretty obvious). The only way I could get the above demonstration to work was if I left the longer set of tendons sticking out freely, attached to nothing… so that the toe has no preset angle bias as it attempts to travel through the channel:

IMG_6837

However, in order to make it work at this point, all the little purple pieces sticking out had to be pressed down together at the same time first, or else everything would bind up and destroy itself.

4″ PRO-TOE-TYPE 2.0

Each tendon should be attached to its own independent ring…

…so that when the ring attached to the inner set of tendons is pressed downward, it causes the toes to tilt upward first as they begin to move down through the channels. Then the top ring hits the second ring below it which the outer tendons are attached to, and then the two travel together pushing the toes outward the rest of the way while maintaining the slight upward torque. This allows the toes to torque gradually as they travel through the channels, without binding up:

IMG_6818

This second prototype (above) is more or less final. I’m going to fine tune it from here, but something very much like this will end up as Noodle’s toe-feet.

The greatest part about this design is that I have nearly 36mm wide of space in the middle to fit his secondary foot function! … ( ? ) … Which is tasting if you didn’t know!

Stay tuned for my next post on the development of Noodle’s TASTING FEET; small silicon wedges that will salivate and lick:

Screen Shot 2015-12-06 at 12.19.14 PM

As I typed that it just occurred to me that I’m pretty much making a tube that can grip onto something while licking and drooling on it. -heh- He’ll have four of these devices. Noodle will be feared by other robots his age.

The only downside to these new complex feet is that I’ll likely have to learn to knit him a pair of custom socks for Christmas. (and I think I actually will) ❤

Read about my past progress on NoodleFeet on my website!

More to come soon!

Eye of Toast

IMG_2187.JPG

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 day without a set of eyes to look into. So… I decided to fix this.

Not just any eyes will do either. They have to be capable of showing a multitude of expressions, particularly the sly and judgmental sort. Instead of using an LED matrix to form shapes, I thought it’d be a bit cooler to make my own modified segment display. Once turned on their side, a standard twelve segment display is capable of showing not only numbers, but all of the expressions a toaster might make too!

CUSTOM BOARD MAKE!

Again I took to Eagle CAD and prepared a board which I’ve called, “EYE OF TOAST”. You can see where the segments are- and where the LEDs will be installed.

Screen Shot 2015-08-11 at 9.49.16 PM

3D PRINTED EYE FIXTURES

While these boards were off being fabricated with OSH Park, I worked on designing the fixture piece that the board would sit inside of. It would need to be as thin as possible, yet also able to defuse the two point sources of light in each segment… this took a few revisions.

IMG_5910

My first prototype was a dual extrusion piece (the two-tone ones). These worked alright, but the white obviously stands out a bit too much when the segments aren’t in use.

I printed another solid gray fixture with a seamless .5mm layer on top, so that the light can pass through just fine, but when the LED is off, it disappears (bottom left). This was our winner.

THE MANY EMOTIONS OF TOAST

Additionally, while I waited for the boards to arrive in the mail, I brainstormed what the actual emotions would look like. I printed out a sheet of paper filled with pairs of segmented eyes and started coloring them in, just like an assignment in kindergarten. It was amazing how many different expressions I was able to muster from these 24 lines!

toastEye2

Once my happy purple envelope arrived, I got busy soldering all the tiny bits in their proper place. Since there have been a lot of ATMEGA328s floating around my life lately, this was the chip I decided to use for this project. So, I’ll be programming in the Arduino environment also.

toastEye1

PROGRAMMING ARRAYS!

I learned all about arrays for this project… which Mark held my hand through (and at times told me to step aside so he could just get things working).

Once I made ints for all of the expression I drew up on my toast ‘homework’ sheet, I could then call them easily in my sketch without having to type a bunch of numbers each time. The function I’m adding to the toaster is that he cycle through expressions every time you pull down on his lever. So, we added a switch to the code as a toggle button.

TOASTER SURGERY

After the code was tested and finally working correctly, the next step was to install everything on the actual toaster itself… which is where things got a little scary for me. I decided that this wasn’t the time and place to cut into toaster’s pristine shiny casing in order to permanently install the eye fixtures. Instead, I’d be attaching them onto the surface of the casing. Less cool, but less risk.

  • This meant I was going to need to run wires from the eyes on the surface into the guts of the toaster wherever the power supply was going to live. I decided on using a USB rechargeable 5V battery; one that is flat, slim, and can easily slide into the toasting chamber like bread.
  • I would also need to install the limit switch somewhere along the moving parts of the lever, yet preferably in a place that isn’t visible from the outside.

For the internal installments, I prepped a soft and well lit area for toaster’s opening and began my descent into century old crumbs and rust.

IMG_5930

The first layer of defense wasn’t too hard to break through… it was held on by some screws:

IMG_5937

Once the “crumb guard” was off, I was able to remove the plastic ring around the bottom of the casing:

IMG_5943

At this point I already found a possible location to install my limit switch. It was near this lever bit in the middle that had some motion, yet not so much motion that the switch may be missed completely or dislodged.

I designed and printed a little bracket to clamp in place between the two bread slots:

IMG_5947

Here it is installed. The lever actuates just enough to press it:

IMG_5959

I could have been done at this point… but some part of me wanted to get the rest of the toaster dismantled just because. ANNOYINGLY there were a few things in the way which were preventing me from removing the chrome outer shell from the heating element inside. One of those things was the toaster’s plastic lever arm, the other was his twist knob. They were effectively pinning the casing to the guts within.

IMG_5963

The plastic arm on the lever was easy enough to detach as it was held on with a set-screw. The twisty bit however appeared to be press-fit in place and impossible to remove… which was bad pizza. It took an hour of careful twisting, pulling, and fondling before the age-old grime crumbled loose and we discovered there was a pin on the end of the knob that could unscrew. Once we finally figure this out the case slid off with ease (and allowed a bunch of others piece to fall out of place-heh):

IMG_5986

From this point on, toaster got to watch me perform a deep cleaning on the rest of his insides, which were caked in rust and chunks of buttery, burnt bread crumbs.

IMG_6027

I took care to save all of these crumbs that I removed in a little plastic baggy… as I believe if you are a hundred-year-old toaster, your bread crumbs are kinda like your soul. Besides, I’d have felt bad discarding crumbs that have survived in this world three times longer than I have.

After a nice cleaning, I put everything back together… which was A LOT harder than taking it apart. Nothing wanted to slide into place quite right and there were also these long steel pins that came dislodged from the inside, which I had to re-thread with a pair of players and a flashlight. =/ In the end though, I got him back in one piece with the wires to his new augmentations ready for hookup:

IMG_6002

The last step was to measure, cut, and solder these wires to their appropriate pins on the eye PCBs. Afterwards, I added little squares of double-sided silicon tap to the back of the eyes and stuck them onto the casing:

IMG_6008

I carefully added a thin ribbon of gaff tape along the seam where the eye fixture meets the chrome as to seal off any light from leaking out:

IMG_6023

TOASTER has never looked so happy or sarcastic! I was relieved to see that everything worked as expected once he was plugged in. The switch I installed functions perfectly and the expressions have just the right effect.

IMG_6031

I’VE COME TO REALIZE

Toasters are complicated little machines! I’ve seen toasters on sale for under ten dollars in ‘dorm essential’ sections of stores, and this feels shocking to me now. It’s true, they seem so basic and primitive… you press the lever, bread goes down, some heat happens, and then the bread goes up again. They aren’t channeling the entirety of human necessity like smart phones, and for that they are easily taken for granted. HOWEVER, there was a lot of engineering involved in the creation of these little mechanical devices that serve to warm our shitty bread without fail time and time again- and they haven’t changed much over the years. I believe there is a whole movie about this! WAIT- Yes. It’s called The Brave Little Toaster. I think I shall go watch it now for nostalgia’s sake.

As a child, that movie gave me my love of all inanimate objects. Once I saw it for the first time, everything on earth was alive. Cheers to that old seed…

AND hug your toaster next time you see it. It’s a work of art.

IF I WERE TO DO IT AGAIN…

…I would likely buy a new toaster that was designed to look vintage and permanently install the eyes in the casing itself instead of just adhering them on the outside. I’m willing to bet that a newer model would be made of a thinner metal, thus easier to alter, unlike my classic toaster’s blasting shield of a chassis.

There was also the idea of cutting micro holes for the light to pass through on the surface of the case so that the LED fixtures could be mounted inside. This would make the toaster look completely unaltered when the LEDs are off, and when in use the chrome would appear to illuminate like magic (or the charge light on your Macbook).

IN THE END

Alas! Another physical manifestation of a creature from the graphite dimension! If you wish to know the back story of toaster, NoodleFeet, and all of the other things I build, check out my webcomic GravityRoad; ideas begin in 2D.

noodleFeet : Animating the Noodle

I’ve spent the last week learning After Effects. For someone who uses Illustrator on a daily basis, this feels a lot like discovering the magic hat from Fantasia. Among other things, AE allows you to turn a vector based 2D image into a fully rigged character for animation… and it’s even easier to do than you’d think.

I had the idea a while ago to make a series of videos about Noodle and his adventures to Mars… The original plan was that they would be stop-motion shorts, made with a tiny 3D printed version of noodle as the puppet. There is no better terrain to fake as the surface of Mars than our very own desert outskirts… but alas, it is HOT out these days. Even if I could handle the relentless sun (which I can’t because I am WHITE), the PLA that the tiny noodle is made out of cannot. So much for the stop-motion thing.

IMG_2094

For scale (his eyes light up and his feet can hold AAA batteries to power the LEDs):

IMG_2088

I still wanted to make the short videos, so I started thinking back to all the annoyingly complex animation software (like Flash) I’ve used in the past and decided to give AE another go. Since the last time I made an animation using After Effects, they added the puppet pinning feature. It allows you to animate a single layer image by creating a fancy deformation map inside of it that can bend and warp. This means, instead of needing to connect pieces on separate layers together through a process of parenting and careful organization of anchor points… you can just rig one happy image with some bones, and you’re ready to pose your character with cool jello-like properties.

This happened to work SWELL with noodleFeet, as he is essentially a creature of wobble wiggle nature himself. After a long day spent watching tutorials, I got off and running and managed to make my first animation last week.

I still intend to produce a few more of these, but we’ll see how far my patience goes. Though it’s easy to animate, it’s still time-consuming to do it right. Once I attempt to introduce physics into the mix, I may hit a wall… because I’m too cheap to buy one of the fancy addons you need in order to generate the effects of gravity. Bastards.

The best part about having animated noodle walking is that it actually may have helped me understand how to program real-life noodle to walk better. So really, this turned into practical R & D. Ha!

Enjoy getting to know my baby a little better. He is the feet.

Maker Faire 2015

IMG_1838

I’ve been home for almost two weeks now from our Bay Area pilgrimage and life has pretty much reset. I rewarded myself by binge playing Starbound all weekend and partaking in other mindless immersive activities I’ve been too busy to enjoy so far this year. It was a nice break.

But back to work! I’m going to close this chapter by recapping our big adventure:

Over all, Maker Faire went firkin awesome! Last year = shitty location + loud tesla coils + high maintenance demo + no place to escape for peace and quiet. Since we had ample time to plan, we eliminated all these stress points!

TRANSPORTATION

deltaLoaf

Our project this year was three times bigger than before at 84 individual nodes, so smashing them in the back of Mark’s Kia wasn’t an option. We didn’t quite have the money to spend on buying our own permanent trailer either, so for this trip we rented one from Uhaul. Quite snugly, three stacks of four delta pallets fit like Tetris inside with the rest of our props and support material wedged around the edges. Add in a crap load of the giant plastic wrap and everything was tethered solidly in place. No sweat.

I had a drink before opening the trailer once we arrived because the freeway up the central valley was more or less one unending pothole from hell. Happily, in spite of the violent rattling, everything arrived just as it was stowed. (Stress test for the babies as well as mommy too!)

…And nothing melted either. We traveled on a cool rainy day… which was lucky because one of my fears was that the heat inside the trailer would exceed the low melting point of PLA and we’d have nothing but piles of yellow sticks upon arriving. >.<

SET-UP

With more to show, I figured it was worth requesting a larger central location away from the chaos of the tesla stage… OH, and barriers. We were pleased to have been assigned an excellent spot in the middle of the dark room that had ideal visibility. On top of that, we sorta lucked out because Arc Attack wasn’t even there this year… which means I didn’t have to wear my Ryobi headphones to keep my brain from melting.

From the get go… we engineered our installation to function as a fort capable of fitting two people comfortably inside. So when you look at these pictures, imagine me sitting on a stack of moving blankets with a table, fridge and laptop around me. That’s right, we made a DELTA ROBOT IGLOO. And it was the coolest part about our installation this year…

THE SHOW

Due to the fact that our installation was automated rather than interactive (and completely caged in by barriers), Mark and I didn’t have to babysit the deltas and actually got to walk the rest of the show!

Here is Mark’s tour of all of the neat stuff in the dark room this year:

Instead of having our robots run slave to a Kinect, which has only been grounds for trouble in the past… Mark figured out how to control all of the robots as light fixtures in a pieces of DMX software called QLC+. This enabled us to orchestrate ‘shows’ consisting of preset motion and light patterns that the robots would circle through all on their own.

As for feedback, who wouldn’t like a mountain of dancing robots with twinkling light? Our display went over pretty well with the attendees… and we had a couple of fun moments in the limelight getting interviewed by press and the like.

TEARDOWN

Once everything was said and done, we loaded the pallets up onto a pushcart, four at a time, and walked them out to the trailer in the parking lot (which expedited the deconstruction part). I was sad to see our nest get dismantled, but eager to get to the Bringahack dinner and have another drink.

This trip was infinitely less stressful thanks to some better planning and all the help we had from our friends. (Thank you!!!) I have great memories to immortalize through illustration over the next few weeks. I’ll also be posting about the fate of Noodle soon.

❤ Thank you for being with me on the summit of my shit mountain. It’s taken a lot of support and sacrifice from the world to pull this into reality for which I am extremely grateful.
