SPUD (Specially Programmed UwU Droid) Mechnomancer 11/10/2023 (Fri) 23:18:11 No.26306
Henlo anons, Stumbled here via youtube rabbit hole & thought I'd share my little side project. Started out as just an elaborate way to do some mech R&D (making a system to generate animation files on windows blender and export/transfer them to a raspberry pi system) and found tinkering with the various python libraries a kinda neat way to pass the time when whether doesn't permit my outside mech work. Plus I'd end up with a booth babe that I don't have to pay or worry about running off with a convention attendee. Currently running voice commands via google speech and chatgpt integration but I'm looking into offline/local stuff like openchat. WEF and such are so desperate to make a totalitarian cyberpunk dystopia I might as well make the fun bits to go along with it. And yes. Chicks do dig giant robots.

Ok, replaced the bottom of the ribcage with a new 2 part bit for reasons nobody would really care about (easier to swap out the part that previously wore out in this new iteration) and wrote a batch script to adjust all the face graphics to fill up the mask face more. Doesn't look too shabby for 15 minutes of mucking around. Next gotta test the servo control boards and map the servo channels for the arms, calibrate the positions, then find a way to mount the power converters.

Its a small thing: Spud randomly looks around/turns neck while the main program runs. Not sure if I can get a neck tilt in there, but I can try.
>>31605 >>31615 Thanks. Good luck with your efforts, Mechnomancer. :^) >>31616 Excellent. Glad to see you tackling the many & varied, so-called 'secondary (ani)motions' [1]. As with the exceptional sensitivity humans have to facial (ani)motions, we learn to spot this stuff from birth. --- 1. https://www.youtube.com/watch?v=uXHnudwQde0

Thinned down the thighs by trimming the bits covering the PVC couplings, and quickly wrapped some foam around the shins. One of the buckets full of outdated SPUD parts lingers nearby :D
>>31625 oh, interesting legs!
>>31625 As with our combined suggestion to SophieDev, I suggest you save these artifacts for the Robowaifu Museum(s) sure to come. Same to every productive Anon here, IMO. Thanks for the update, Anon! Cheers. :^)
>>31628 Unlike my other projects, SPUD's old parts dont take up a lot of room. Got a pic of a full body shot and a video of SPUD looking around. Eventually I have to do something about her giraffe neck, but in the meantime I'm working on some a new joint for the neck piston that will hopefully eliminate some of the slop by using a universal joint instead of a balljoint. I stole it from inmoov, but the thread for the screw only goes a few centimeters into the piston body so I have lots of room to make it shorter. Also it appears the PI will randomly cut power during operation (It is running an image recognition AI and compositing images at the same time after all) so I'll have to run that USB power from elsewhere.

oops, broke the servo horn mount by running one of the servos too fast. That's what I get for only 10% infill. At least I got the servopulse sequence figured out, so all I have to do is link it up to voice recognition. But now I get to reprint the shoulder piece in a lovely orange color at 50% infill :3 I also rigged everything to run off a single AC powerstrip: usb adapter for the pi, usb adapter for the oled, usb adapter for the servos and a 20v adapter for the chonky motors. It's a spaghetti mess but it runs. Some foam scapulas bring the back together. However there's some balancing issues so spuds arms have to be turned forward -scapula's apart- or she will fall back. A good thing to add to a dynamic balancing script.
You arent going to make a plate for knee caps? Looks weird without something that simple.
>>31636 New shoulder joint first ;) Being 50% infill its going to take a while Kneecaps will be a variation of the elbow pads.

Aaaaand phase 1 is complete.
>>31647 A cute! Great work, Mechnomancer. So, is dear SPUD soon to begin a career as a 'robo booth babe', or what? :D This has been great fun to watch you develop this robowaifu, and an encouragement to all the Anons here. Thanks for providing lots of details along the way. Cheers, Anon. :^)
>>31648 She - along with some other projects- are going to be on display at an upcoming local convention. So will be her maiden voyage as a booth babe (last year doesn't count cuz she's more or less the ship of theseus). Once that is over I'm going to be re-printing some parts at a higher infill and re-configuring the animation scripts (movement in the video was hard-coded).
>>31642 That's a bit better though im not sure why you went for a flat plate design and didnt just get some used sports knee and elbow pads to use. >>31647 Cute but she sounds in a bad need of some lubrication. So squeaky. Also is SPUD left handed?

>>31693 Its a robowaifu not a rollerball chassis so no sports equipment. Knees/elbows inspired by some Subaku artwork. Motor noise and squeakiness are to be expected from cheap motors, less noticeable IRL.
>>31734 I just meant it might look better with a subtle curve like the image on the left. Up to you though. Ah yeah true sometimes microphones pick up things we dont really notice with our ears in person.
>>31647 Great. Good work. Did the question ever come up why you don't upload these shorts to some Youtube channel? David Browne got 250k views on one of his videos about Hannah recently. It's not so much about money, especially "shorts" are worthless and can even harm a channel, but it would create more attention. > Stumbled here via youtube rabbit hole This is where I make the most advertisement. I drop alogs/robowaifu from time to time, which works better for copy and search. I also have an avatar with the term /robowaifu/ in it, some people might recognize this as something referring to an image board. Anyways, I'm not doing this all the time, since "self advertisement" is sometimes not welcome and might at least be seen as rude.
>>31747 Funny enough, youtube will simply refuse to show many of my shorts: youtube will usually try to show shorts to 1000 people in the first 24 hours to gauge interest, but anything robowaifu related wont. (Although a few of my other shorts on another project did get nearly 10k views). If I were to guess, David gets the views because of how realistic the face looks in thumbnails. Now that I got SPUD more or less functioning in a rudimentary fashion,the aesthetics are something I'm going to really start focusing on.
>>31760 It might also be the tags? I have a suspicion that David started to use some tag like "Alita" and maybe "animatronics". Many people commenting seem to know about these things.
>>31762 After analyzing the metadata, all his vids seem to use the tags "video, sharing, camera phone, video phone, free, upload". Would have to see analytics to know more. Not trying to diminish his work, but the face movements are kinda rather corpse-like. A-working-on-da-face I go!
>>31764 >...After analyzing the metadata Oh, my bad. Instead of speculating, I should just have looked. I don't see him using any tags. That said, GWAStech2 also has a channel with robots, and seems to get ~350 views, sometimes 800. Though a current one uses a current catchy music which makes it more pleasant to watch (don't look up the other videos using the same song, unless you are mentally hardened by Lovecraft). >... but the face movements are kinda rather corpse-like. I didn't really see that. Me and many others seem not to care. It's also about seeing the potential where this is going.
>>31765 Yeah, I get that. I suppose I should've clarified the expressions (or lack thereof) seemed rather corpse-like to me. Then again, I am very good at reading facial expression. He got a a facial expression to not look uncanny valley, we'll have to see if it can continue :) Just goes to show that aesthetics is everything: so far SPUD's face has been a half-hearted obligation for me as I've been focusing on the hardest parts first: body design and code. However my printers need some new parts (bowden tube melted into the extruder) so I won't be doing any work until the new hotends arrive :( Video tags are not *technically* public, but easy to find if you know what you're doing.

I know wasu arts was mentioned somewhere, so I took a stab at making a 2d animated face with eyes moving on 2 axis and blinking eyelids. I'll automate this and the uncanny valley will be safely avoided. With better art, of course, the face is a quick derpy scribble to check out how it will work.
>>31784 Interesting. Though, unlike a display, the servos moving the elements would make noises. On the other hand, it would an option to cut down on costs.
>>31784 That's impressive. Something so simple, looking that good.
>>31784 this is actually very good. I definitely think leaning into more cartoony/anime styles is the best way to avoid uncanny valley (unless you are not personally satisfied with those styles)

>>31827 A robot without motor noises is like a Reese's cup without peanut butter :3 >>31863 You aint seen nuffin' yet :D >>31888 I think stylization to avoid the uncanny valley is good too, and with this update I am very satisfied. Generated an anime face using Stable diffusion and did a few edits to make it useful, printed it out and pasted it to a 3d printed x/y axis with an additional axis for the eyelid (yet to be powered), then put it on SPUD's old neck: since the head will be much lighter the servos will be under less stress. Probably a good view of the face is 135 degrees or so, any more extreme views can probably be obscured by hair. A gif of the movement, then a video file so you can hear how noisy it is. Next step is to motorize the mouth. Might put a small LCD behind for other expressions besides a mouthflap and eventually slap even tinier LCDs as pupils.
>>31660 Sounds good! Looking forward to a good event report. :^) >>31784 >>31891 Very cool. Papercraft brings a lot to the table for all of us during the prototyping phase. As was pointed out, it's a reasonable approach to ultra-low-cost robowaifu designs as well (>>11446) . I kind of see it as sort of a crossover between papercraft Karakuri and Visual Waifus (cf; >>31835, >>14180, >>240).
Open file (290.58 KB 808x1073 SPUD's new head.jpg)
Did a head transplant, now just gotta clean up the design a bit: probably just add the trapezeus panels back on. Tempted to just make an entire separate face to work out the eyelid/mouth servo integration so I don't mess up what I got here.
>>32033 A cute! If you can afford to do so, I think it's smart to sort of do 'leapfrog'g with revs of your subsystems (like her head). That way, she'll always be in a ready-or-near-ready state. Cheers, Mechnomancer. :^)
Open file (76.37 KB 674x541 face mechanism.jpg)
>>32043 >leap-pepe revs of subsystems I just might do that: The mechanism itself is relatively simple, and attaches to the skull baseplate (yellow) via 2 machine screws. The most expensive part is assembly time: cutting out the eyelashes and gluing the various paper bits onto the 3d printed structure with accuracy. And working with those itty bitty screws on the sg-90s. Still have no clue how to add eyebrows on the dang thing lol. I suppose I could capitalize on the premiering anime by making a face based on Mina from "My Wife Has No Emotion", although that means I'd have to suffer the dorky MC in order to speak with authority about it.
>>32053 >Still have no clue how to add eyebrows on the dang thing lol. Possibly you might consider the simplistic approach used for the SEER head (cf. >>15287, >>31917) as a way to just get started with it? Good luck Anon! Cheers. :^)

Open file (212.76 KB 339x548 eyelid panel shape.png)
>>32054 Its not how to make the eyebrows, it's how to add them: the eyelid panel is literally in the way of putting any servos in there without some sort of linkage. :D
>>32056 Kek. MAGNETS -- HOW DO THEY WORK!!? :D >>32058 Maybe some sort of vertical linear grooves cut out of the eyelid panels, that would allow the eyebrow control shafts to pass through (and the panels would then slide past)? IIRC, the Nandroid designs seem to have similar grooves on their brows (one above each eye; cf. pics-related : >>31769, >>31895) ? I think you could even make the groove cutouts less conspicuous by stationary backing panels printed in the same color as SPUD's face? >=== -minor edit -add crosslinks

>>32059 I could use some thin linkages to get motion between the eyelids and the face surface, or -I'd have to do a check of the tolerances- just slap the servos between the eyelids & face surface and have the eyelid bend backwards into the head. Got some screenshots/references for Mina. Might make the entire head a simple papercraft ("it's just like in my Japanese animes" lol) Also printed a 2nd face mechanism with all 4 servos (x/y eyes, eyelid & mouthflaps)
>>32130 OK it'll be interesting to see how you solve it all, Mechnomancer. Good luck. >"It's just like in my Chinese cartoons!" Haha. Weeaboo! :DD Mina may be a great choice r/n, yeah. You might be able to gauge any of your booth visitors' power levels if they recognize her anytime soon, heh. Cheers, Anon. :^)

>>32133 Neat! Are you going to do her neck too, Mechnomancer? Mina's neck is kind of a trademark for her, right?
Open file (28.29 KB 449x525 Mina_neckcollar.jpg)
>>32156 I suppose so, after watching the first episode Mina doesn't seem to have any mouth movement, so that makes things easier. A nice papercraft collar would be nice to cover up the new, bright orange neck anchor I installed on SPUD. :) I just quickly stitched together some screenshots to get a rough idea for the collar graphic with the dimensions approximating how it would fit over spud's orange neck anchor. tbh it is probably good enough... idk.
>>32158 >tbh it is probably good enough... idk. FWIW, yeah I think so too. Looking forward to SPUD's newest head reskin! Cheers. :^) >=== -minor edit
