This is exactly what I should be watching at 2 am

Finally, my childhood dream of witnessing the arise of real life Zoids is ever closer

man this would be so cool to mount onto my wheelchair. my disability makes me very short (3ft) and weak but i have semi normal arms. i can imagine using the hand tracking to open doors for myself or grab stuff thats normally out of reach or too heavy.

I’ve never seen inserting parts during a print taken to this extreme, it definitely seems like it could be useful in some situations. Shafts really don’t do well printed vertically though, most 3D printing materials are weak in the Z direction due to layer adhesion. A technique I have seen to strengthen prints is to insert a bolt through the middle of the shaft and a nut at the other end, this adds reinforcement, the same could be done with any metal pin or bolt really.

The first step to start is that you need money, Tons of money.

At what part will the mouth of an apple user be surgically attached to the anus of another apple user?

This is the coolest Quadruped Robot design I have seen so far.

ur crazy bro

From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainty of steel. I aspired to the purity of the Blessed Machine.

As someone whose hands are starting to fail this project couldn't have come at a better time, I'm really impressed with the wrist mechanism but don't like the fingers. Very inspiring, well done.

cool project. It broke a fundamental rule that made everything more tortuous: you over optimized cool hinges with overengineered joints. which are fun, but you could have done that after you tested the most likely failure point: the gearbox. you wasted too much brain in the cool factor, which made you negligent to critical parts. but again, really amazing project. and the over engineered parts are kind of fun, and I am quite sure that they will sell (in youtube) better than heartless efficient engineering. I will be waiting a part 2.

Fantastic work. Great ecoerimental thinking and quite fascinating.

Great robotics work horrible video

Dang Bambu sends X1's to influencers like candy i better get to uploading

Excuse my ignorance, but doesnt the friction of the plastic of the gear in part cause to the breaking? Would a simple small bearing not address this issue?

Maybe if you skip the whole rotating shaft and design the legs to operate based on pulling a string you could make the whole leg mechanism a compliant mechanism with no assembly at all. This would also allow you to make the centepede a lot smaller. Ypu could probably get a ”wave pattern” in the legs by having a bit of slack in the string between each leg module, but might be difficult yo achieve, especially if you want the wave to contain multiple wavelengths along it’s body. Might be able to design some compliant mechanism that does multiple oscillations from a single pull, but that’s probably difficult. Would be really cool though to have a basically life sized remote controlled centepede :p

Very good video, testing ideas and reflecting on the results. So I can learn. New subsciber.

stl to print and experiment?

I also struggled with proper hinges. I came up with using shoulder bolts with heated inserts. They come in a range from sizes and are super strong. Maybe right for this application

Would be interesting to do similar with 3D printed compliant mechanisms. Reduce part count.

Hey there! I found this video very inspiring, the multi stage printing sound like a very interesting idea. I have been designing mechanical parts for a while but never really got in depth with gearing systems, and fusion360 doesn't seem like the ideal program to explore them. Which program are you using to design these components or suggest using? Thank you for your help!

I never know if I could do this but then I remember that a couple years ago I was very clueless in geography and now I'm. Amazing at it

You mentioned friction issues multiple times, have you attempted 3d printed bearings with graphite powder as a lubricant? It does introduce a little slop but putting two in a gear on top and bottom can mitigate that for the most part This is a cool project and I can't wait to see where it goes

Have you tried printing the parts which require a lot of support, from petg? If you set pla as interface layer, you can set the distance between support and model to zero to get a close to perfect overhang, and the pla snaps right off, allowing the support to be removed very easily.

So cool. Keep up the good work!

Cool projects and dedication.

Man all of your projects and videos are gold

The exclude object part that BambuLab uses is also available in octoprint and klipper. It relies on the slicer "segmenting" the GCode with object start and end markers and just skipping those during GCode execution.

You can solvent weld ASA and ABS with acetone if that will help stiffen your assembly.

awesome

“Take that maths!” 😂I love it. These videos always blow my mind. Well done Will ❤

Next step a mechanical human centipede 😈

Damn, I watched that whole thing expecting to see the functioning centipede at the end! I was so surprised when it ended lol

Very cool video!

You can use fasteners for hinges two ways: use shoulder screws, which are only threaded partially at one end, or run the screws through a sleeve/bushing. The bolted pivots on a full suspension mountain bike are an obvious example.

I never thought about printing a gearbox like that, nice work!

Try PLA Tough, all the strength of PLA with none of the brittleness issues. I use it exclusively for everything and stopped bothering with ASA/PETG/etc.

Hmm... are you designing in proper tolerances into your parts? Getting into the habit of throwing parameters in for tolerance and then being able to adjust it at the end parametrically is, IMO, a good practice to have for minimizing parts not fitting or working as the stimulation did.

Interesting experiments! I've been thinking of playing more with mid-print inserted parts too, but it seems to be quite problematic. Prints detaching from the build plate, especially. I'm beginning to think it's wiser to just design the parts to be glued together afterwards!

neat ideas, thanks for the video

oh my, stumbled onto this in my feed today. did not dissapoint - new sub!

Is is only me that felt audio was really f'd up!? You probably need a multi material printer with a multiple nozzle like Prusa Xl to get the results than AM's which is more of multi color.

really interesting approach! as always, and indeed the bambu printers are impressive as well

hello! where did you guet the xbox cad drawing?

Great print-in-place experiments. Don't give up!

Fantastic as always

Another thing that you might have overlooked is that the printing orientation of the gear shafts. The shaft printed in that orientation are generally weaker due to the layers. And it can be seen as the main gear broke off several times. I hope this gets fixed in V4

welcome back Will. great project

Very cool exploration -- definitely got my "gears turning", haha! I have made some very durable designs with cams and linkages in PLA by using finish nail shafts as low-cost pins, sandwiched in clamshell assemblies to support both ends. Where unsupported printed hinge pins are needed, biasing the contact patches toward the bases helps longevity by reducing leverage on them. Thin raised "rub rings" to reduce the contact patches between sliding and spinning parts also help -- it looks like you did this, but I prefer to bias mine toward the outer diameter for more stability and reduced contact force. I do have to say, this design seems like a big ask of any motor since there's so much rotating friction (it would be a lot even with ball bearings), and I wonder if you'll end up needing supplemental power sprinkled along the chain. Looking forward to the next version!
