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 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…

Robot Army : Printing + Drinking

March 20, 2014spetku2 Comments

Nitrogen Capsules = LED Diffusers Here’s a St. Patricks Day story for those of you who are into that sort of thing. As you might have gathered, Mark and I like to drink beer while we work. Lately our brew of choice has been Guinness. We’ve been so busy now that we’re in fulfillment mode that we’ve neglected to haul our empty beer cans from the past two or three weeks to the curb. There is a mound of them piled in the corner of the kitchen waiting to be tripped over. In short, we haven’t had any luck finding a more reasonably priced lens to go over the LED of our robots. The one we had found, though perfect in size and shape is freakishly expensive (We’re talking several times more than the amount we allocated for that part on our BOM). We had given up on finding a…

Robot Army : From Tupperware to 3D Printing

February 27, 2014spetku6 Comments

When I moved back home from art school in Chicago, one of the biggest drags was no longer having access to the beefy machine shop that was down the street from my apartment. I went from playing with a room-sized lathe and mill to having little more than a $20 soldering iron and dremel at my disposal. It seemed my metal-cutting days were going to end as soon as they started… well enough, this didn’t stop me from making the things I wanted to. I just had to use plastic now instead. Luckily for me, plastic was in abundance at my parent’s house. My mom hordes take-out containers and tupperware, so I had a bottomless stash to carve up. Still pursuing my vision of creating the field of robotic flowers, I was trying to refine the design of my ‘steam’ into something a bit more controllable. At some point I…

Robot Army : Final Stretch

February 24, 2014spetku0 Comments

It was fun having our Kickstarter in tandem with the Olympics. It felt like we were participating in our own sort of event. As I watched the closing ceremony last night, I felt sadness because I knew our ship is setting sail soon and I’m at the point where all I can really do is sit tight and wave goodbye. We have less than a week left and I don’t want it to end. It feels like much more could have been done in regard to press, but Mark assures me that PR is sort of like the lottery. If I could accept that I’d stop banging my head over it like I’ve been doing, but alas… it seems I can’t. tehe. Our campaign has been an exciting experience over all. Now that we’re switching gears from messy uncontrolled busy to just plain busy, I’ll be able to do some…

Robot Army : Push Notification Dance

February 17, 2014spetku2 Comments

How awesome would it be if you had an adorable little robot bob up and down to let you know when you receive a tweet, message, or get an update on a feed? SUPER AWESOME! In order to provide a more utilitarian use for our delta robots, we’ve mocked up some example code that scans JSON packets from the internet in order to trigger a response of some sort. For our first project related update Mark wrote code that causes a delta to dance around every time we receive a new backer for our Kickstarter (our robots should be as happy about that as we are). We let this application run all day on Tuesday to test the reliability of the code, however by doing this we apparently opened a rift of unfortunate irony… and didn’t receive a single backer ALL DAY long. This resulted in one very sad stationary robot and…

Robot Army : Kickstarter Video Do

January 13, 2014spetku1 Comment

Somehow, just as I was starting to recover from whatever it was I picked up over the holidays, I managed to contract another illness. I’ve spent the entire year so far being sick… which SUCKS because it’s slowing me down. I was worried about whether or not I had gorilla glue hanging out of my nose while making contacts throughout CES, and I had to cough in the middle of every shot while filming today. I don’t even have that sexy raspy quality to my voice to make up for it. BLAH! Mark and I filmed my main monologue and a couple supplementary clips this weekend. We want the video to spoon feed the viewer all the important details about the project while throwing in notes of playfulness bordering on insanity. This takes some finesse. As such, while Mark was away at work today I gave my speaking parts another…

Robot Army : CES Week

January 10, 2014spetku0 Comments

This week was exhausting. It involved a lot of walking, chatting, setting up, tearing down, and practicing the good ‘ol elevator pitch. Myself, Mark, and his friend Gregg took off to make the most of CES- exploring for two long days on the showroom floor, and then attending events in the evening. It was a lot of fun and we made some new promising contacts (woo!). Last night we did our first demo with the six working delta robots we have at Pololu Robotics. They held a nice shindig for those attending the convention who were involved with robotics and hackable electronics. It went over well and our kids did a fantastic job, seeing as it was their first recital. >.< Now to double our numbers… Mommy and Daddy must get busy. Finally, with a moment to relax, Mark and I went over our BOM and caught up on emails…

Robot Army : Cuddling my Spreadsheet

November 21, 2013spetku5 Comments

Today, I find myself wanting desperately to feel as though I’m doing something right. I think it’s likely all the rain we’ve had that’s tainting my mood, but I’m discouraged. I’ve been adding things to my bill of materials and the proportions are seeming less than hopeful in some areas. Now I need to start shaving cost off things that are needlessly spendy. I guess this is where I learn to be inventive and shrewd all at once. It might just be my lack of experience in doing PR related stuff- but I’m stuck again with the getting the word out part. Maybe I’m not begging loudly enough. I’ve never been all that good at asking for attention. So this is another hurdle to overcome. This morning I did mock ups of several different variations Mark came up with for my delta’s arms. We foresee the cups that hold onto…
