>>44052 >It's more realistic to strap robots to roombas for now. IMHO, this is kinda like frens suggesting the Python programming language is all you'd ever need. OTOH, somebody has to write in a systems language like C++ to even make things possible. Bipedal locomotion (cf. >>237 ) has always been the long-term goal in general. Cheers, Anon. :)

>>44055 Of course, not arguing it isn’t. But compared to other elements of a functional robot it seems like the hardest part and best left for big companies to develop first (even those companies who’re trying to deliver walkers are running into issues and pitching wheeled alternatives). One I found interesting is Lovot, it’s out and available for anyone with enough money, but I imagine if they tried to make them bipedal it would be even more expensive or still a prototype I know a wheeled alternative comes across as lame, undercooked, etc so I’ll shut up about it and let you all cook

>>44056 >I know a wheeled alternative comes across as lame, undercooked, etc so I’ll shut up about it and let you all cook Hehe no need for that, Anon...speak your mind freely! Debate is a common feature of our culture here on /robowaifu/ (and rightly so). :) BTW, we have several threads here discussing the topic of wheeled robowaifus in some depth : >>2983, >>24744, >>15630, >>29219, >>11446, et al. --- While you're definitely right that this is a challenging area (however the C4 control software development is by far the hardest part IMO, hands down), there are obviously already functional 2-legged robot examples being prototyped commercially r/n. * BTW that thread I linked you to was one of our OG threads from back on 8ch. And we were discussing this very topic of bipedalism as a difficult challenge even during our 4cuck formative era. ** So the >tl;dr here is that we've been bouncing ideas around about this topic for quite a few years here in the DIY domain. IMHO its long past due for us to make solid progress toward this particular endgoal. <---> But again, thanks for your inputs Anon. And please don't feel you're being 'shut out' in any way. Newcomers are always welcome here on this board! Cheers. :) --- * confer : https://trashchan.xyz/robowaifu/thread/26.html#1396 et al ** (cf. >>14500 )

>>44050 >May I suggest you begin formulating a plan for a rolling gantry that moves along with dear SPUD during these formative years? Related: https://trashchan.xyz/robowaifu/thread/26.html#1400

>>44056 Don't worry I understand ya. But I pretty much have written all the code I need, I just have to unify it all under 1 master script. Last year I was publicly exhibiting SPUD, having her talk to people and stuff (I was using a big LLM at the time so it was kinda slow tho, should be much faster now). Have code for servo "animation", modular scripts/expressions (just put your files in the folder and name them), speech to text, LLM, text to speech... >>44062 SPUD already did a faceplant last year. Damaged her paper face and I think only one shoulder joint but I didn't notice the joint damage until recently. Maybe it also started her spine damage but again only 10% infill parts. But certainly no parts came flying out XD I could probably modify SPUD's current stand to be a rolling gantry. Meanwhile, I installed the hips and started roughing out the leg dimensions in cardboard. Its looking like the initial width for the hips is too narrow, so I got some more old parts out and glued them together to make a wider servo holder. Just gonna wait until it is fully cured before installing it P: The servo horns (blue) will be centered around the new axel positions (red), should be wider and make for a more stable robit. Also more ability to turn the legs. I think I might put SPUD's battery in a shoulder bag or something for her to wear. It would be funny.

>>44063 >SPUD already did a faceplant last year. Yeah I remember that ouchie. I was worried about her! :) >I could probably modify SPUD's current stand to be a rolling gantry. Great, I figured so. And it doesn't even need to reach overhead IMHO -- just be high enough (possibly about the waist zone) to provide sufficient lateral support to avoid tipping over. --- >more stable; better turning I bet it will give dear SPUD more womanly curves too! :D >I think I might put SPUD's battery in a shoulder bag or something for her to wear. It would be funny. That should work. If you're going to have her trotting about the convention floor, then you should keep it's inertial moments in mind, design wise. At the least I'd suggest keeping it tightly "buttoned down", and not free-swinging. Good luck, Mechnomancer. Cheers. :)

>>43934 Good points, Anon.

>>44052 Thank you :) I do agree that wheeled systems are the most cost-effective and practical for now. However, I agree with Chobitsu >>44055 It's clear that SPUD and MaidCom are frontier designs, with a lot of RnD into new capabilities. I do hope there are other Galatea-esque models come out soon.

>>44066 You're right, GreerTech. We need pursuit of both lines of R&D (and more!). Cheers. :)

Been dealing with some personal affairs, but now have finally gotten around to installing SPUD's new hips n stuff. I might use some more ASMC-04s for the legs/knees instead of my home-brew acme screw linear actuator system to make things easier to control. Probably replace those cylinders with versions more aesthetically pleasing. Depending how things go I might also remove the torso tilt servo so I could put a few 20V tool batteries into its place.

>>44116 POTD Sorry to hear about issues going on for you but I'm happy to hear you're now past them seemingly. >finally gotten around to installing SPUD's new hips n stuff. This is VERY EXCITING!! To be honest, I've longed for this progress for many a day. >instead of my home-brew acme screw linear actuator system to make things easier to control Actually I liked your ACME design. Only just shy of those Super Genius(tm)(r)(c)(do not steal) rocket skates of yours... :DD What was the control problem with them do you think? Seems like they were relatively compact & lightweight AFAICT. >Depending how things go I might also remove the torso tilt servo so I could put a few 20V tool batteries into its place. That's certainly a prime spot to locate such masses. And I've thought often that (during this era, especially [we can do custom, more-optimized packs later on]) such modular tool battery packs would be a good choice, given their broad availability & compatibility & fairly-rugged durability. Good luck, Mechnomancer. Godspeed. :)

>>44066 >>44067 Almost comically, I'm now considering using two of the little 4-wheel car bases * for my foot/ankle/shin/knee experiments now that I've put the Holowaifu explorations on hold and don't currently need the little mobile tracking marker car. >tl;dr Prototype inexpensive wheeled, wide-foot designs (Roll-style), building the bipedalism literally from the ground up. I'll post picture links in teh Prototyping thread when I have some progress worth reporting. --- * cf. ( >>43082, ...) et al

>>44117 Personal affairs are still ongoing but at least good end is in sight. Anyways... >ACME screw actuator issues It requires more diy hardware than just using a standard servo. Digital i/o board, analog to digital converter, extra coding... I could control acme screw actuators using standard servoboards but I would be limited to a certain speed or risk oscillation. Using a standard servo controlled by an i2c servo controller such as the PCA9685 is just easier. Starting to rough out the basic leg system. 2x ASMC motors in the thighs (thigh/knee bend) and 2 of those larger 70kg servos in the shins to manipulate foot angle. These will have to be split into several parts to fit on my printer, since both my big printers are having extrusion issues.

>>44212 >Using a standard servo controlled by an i2c servo controller such as the PCA9685 is just easier. Heh, OK fair enough Anon. :D >Starting to rough out the basic leg system. I like the way this is shaping up so far! >since both my big printers are having extrusion issues. I hope you can resolve that quickly, Mechnomancer. Are they having nozzle or hot end issues?

>>44212 I'm excited to see truly opensauce DIY legs! Sorry about the personal issues. I have faith that you can deal with them.

>>44213 2/3 printers are having extrusion issues. I think both might be memory errors, as I left 1 printer off/unplugged for months at a time and then started it up for the lulz and it worked for a bit until randomly under extruding. Other printer is simply underextruding when starting a new layer, no matter what settings I tweak. I might try re-flashing the firmware. >>44218 Yeah, opensauce DIY full size legs would be nice, and I'm trying to keep it simple as possible. I'll certainly be building an overhead gantry to help SPUD get used to walking. Big problem I've seen is folks dressing up simple robots to make 'em look more complex. While that is good for youtube views it isn't too good for doing IRL stuff. Personal issues are (hopefully) almost concluded. I feel like toby mcguire stopping the subway train in spiderman 2 XD The leg parts have just about all the greebles and nurnies they need, however a single thigh piece is... a rather chonky print. I'd rather not run my printer for over a day straight just in case something screwy happens. So I'll be slicing up the model some more.

>>44219 Hmm. Do you think the filament friction feed might be slipping? >I might try re-flashing the firmware. Could be helpful. Always makes me nervous lol. :D

@Mechnomancer I'm pleased to report that /mecha/ lives again! BTW, heres an intredasting question I figured you might just know the answer to? https://trashchan.xyz/mecha/thread/138.html#990

>>44220 The sovol could be a slippy feed wheel as it has never been replaced. No reason why my max neo would still be having some extrusion problems despite an entirely new direct drive system. Will be tweaking both of them when I get the chance/it becomes necessary. For now I'll just putter along with my ender3 While I've been working on the legs (reveal for those later, as I have to re-print several parts) SPUD's face has also been getting some attention: servo eyebrows and a more stable pi holder. I also found a USB cam about the same size as the raspi cam, so that eliminates the problem of not enough raspi display/cam ports

>>44310 >>44310 >>44310 Wow her face is really coming along now, Mechnomancer.

>>44310 >The sovol could be a slippy feed wheel as it has never been replaced. Oh yeah, definitely check that. On my old Ender 3 v2, most of the problems were from the filament feeder. I like how the face is progressing!

First iteration of leg is almost complete. Will be re-printing the shin servo holder so it is more thin. Then I start fabricating metal bits: bracket on the hip, servo horns/linkages for the hip/knee rotation, then balljoint linkages for the ankles. First stage of 2 (or possibly 4, depending how stage 2 goes) for silicone face is also complete, but I'll be waiting to post that until the process is complete in case it is a bust. There is already too many creepy silicone robit faces on the internet and I don't wanna contribute :D

>>44343 It's looking good so far! You should document this, it will revolutionize DIY robotics

>>44343 POTD >There is already too many creepy silicone robit faces on the internet This. >and I don't wanna contribute :D Based. Looking forward to the first leg prototype arrangements, Mechnomancer. Cheers.

>>44344 > it will revolutionize DIY robotics Is that how revolutionizing works? just slapping a bunch of stuff together hoping it will work? :D >>44349 slimmer ankle servo block took like 18 hours to print. But it is indeed slimmer. I'll try to slim down the leg a bit by offsetting the knee servo, and I might end up giving her some platform shoes to fit a pair of 40v batteries in... megaman-style boots/legs might be a good choice to fit all the power converters and stuff into.

>>44357 Nice progress. Will the pvc tube be strong enough to support anything? All my admittedly underwhelming experience with this stuff suggest it is pretty fragile.

>>44357 >Is that how revolutionizing works? just slapping a bunch of stuff together hoping it will work? :D Absolutely.

>>44357 Neat. I'd suggest you consider not locating such mass as batteries at the distal ends of limbs. Thrown weight and watnot. BTW, do you have a recommendation on batteries? I'm currently considering power for the cart waifu project.

>>44359 ^

>>44358 >le pvc I use schedule 40 pvc, nearly built an entire mech out of it. So I certainly know its limitations. Short segments are where its strength excels, anything over a foot or so is prone to sagging and snapping. >>44363 Batteries in the robowaifu's feets would help her stay upright, its not like I'm trying to get her to run or anything (walking would be a victory for me), and it seems to go well for the wowee robit line. I like using tool batteries because it already has a charger, battery circuitry, and durable casing (in case robit fall down), but depending on your battery voltage you'll need quite a power converter to take advantage of it (picrel)

>>44368 Thanks very kindly for the advice. I'll keep it in mind. Cheers, Anon.

>>44363 Leg is pretty much 3d printed. Even though there are some spots I don't like the entire thing is pretty stable. Next step is to cut some angle iron and flat iron into the asmc-04 servohorns and linkages.

>>44379 CHONK!

>>44380 >CHONK If being a little thicc is what it takes to keep SPUD from exploding on impact, bring on the thighs!

>>44381 /thread

SPUD leg is almost complete: it even stands by itself. I just need to reprint a few parts as the linkages need more clearance to fully extend. I'll also probably cut down the width of the metal linkages, since they're made out of 3/16" steel. That big piece of angle iron was part of a bundle of materials donated to me by an irl fan a few years ago. Also due to tolerances this will probably end up being the left leg instead of the right. At least I printed both feet so swapping should be easy :D Then I suppose I should design some feets to hold the batteries. That's gonna add a few more inches to her 5' 4" height.

>>44385 POTD Really proud of you, Mechnomancer! Looking forward to your further refinements on these and the operational prototyping. Have you figured out some kind of gantry + harness type thing to facilitate your walking research yet? Its very cool that the individual legs can stand up alone. Keep moving forward.

>>44379 >>44385 Nice, it's looking really professional!

@Mechnomancer This video mentions a smol SPI-to-CAN converter board; both topics we've discussed before. Thought you might be intredasted. Cheers, Anon. :) https://inv.nadeko.net/watch?v=6Lgqm0KW-0g

>>44401 >Open source robit with manual >cloud-based control program >shite documentation with no step-by-step instructions just explanations of random-ass concepts >pretentious robit name of "asimov" >like a 3 foot midget kek I consulted t̶h̶e̶ ̶o̶r̶a̶c̶l̶e̶ chatgpt and got recommended MuJoCo which seems to be an actual robit walking training program (so no hallucinations there). I'll be looking into it to train SPUD to walk. There hasn't been much updates to the leg other than getting the knee to actually bend. So I'm starting to print the entire next leg.

>>44410 Lol, true. :D >MuJoCo >I'll be looking into it to train SPUD to walk. Good luck! Eagerly looking forward to a positive report, Mechnomancer. >other than getting the knee to actually bend. I don't take that lightly, and in fact I'm excited by the progress. Cheers Anon.

You should really update your website, it still has "Lorem ipsum dolor"

>>44567 >update website yeah, I know After printing out the entire 2nd leg I realized I need to re-design the knee servo so the 550 motor on it faces out, not in. D'oh!

>>44571 Nice work! It looks just like a "professional" humanoid robot! *Professional being in quotes because I do not think that institutions are inherently superior

>>44571 POTD Looking forward to this Anon. Cheers.

Mechnomancer, I made a thread about IRL mechs on /mecha/. The thread is like /robowaifu/, but for mecha https://trashchan.xyz/mecha/thread/1075.html

>>44583 Yeah I saw the thread. I could waffle for hours about IRL mech design but I don't have much free time atm. :)

>>44583 Are you going to add that thread to our new "listings" thread? (cf. >>44504 )

>>44587 Sure. I initially made it for just Trashchan /robowaifu/, but we can add our robowaifu adjacent and robowaifu embassy threads
