Self Reversing Screw Mechanism, Walking!

A walking version of my self reversing screw mechanism.
I designed and 3D printed this model for John (AKA Robothut, / @robothut ) to illustrate how I implemented his suggested that the self reversing screw mechanism could be used as a walking mechanism. Stay tuned to his channel to see his skills in creating wonderful robotic designs!
The frame in this model was 3D printed in PLA, the self reversing screw, travelers and bogie housings in Tough PLA, and the wheels in TPU.

Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in PLA, Tough PLA and TPU on Ultimaker S5s and an Ultimaker 3e.

Your imagination is boundless. Good work

Thank you very much MicrobyteAlan, I truly appreciate it!

That is beautiful 😁

That's a really cool mechanism! Also, man, you really like those N20 motors, huh

[@popzct]

Thanks evanwilliams1199, I'm glad you enjoyed it!
I ask for the N20 motors for Christmas, Birthdays and Fathers Day, the kids / grandkids have unique RPMs so I get a wide variety.
Greg

[@evanwilliams1199]

@@popzct Yeah, they come with different sets of gear trains as attachments so you can get a range of different speeds, right? I bought a couple at some point, but I haven't actually tried them yet

[@popzct]

@@evanwilliams1199 Yes they do, I ask the grandkids for 30, 50, 75 and 100 RPM N20s, and the sides for 150, 200 and 500 RPM N20s. That way I have many speeds to test with!

Fantastic, Greg! I like the detailed design of the wheel units.

[@popzct]

Thanks gaWalt, I'm glad you enjoyed this model!

[@tiagdvideo]

Fantastic mechanism - but surely those red and green legs are on the wrong sides!! ;-)

[@popzct]

Thanks tiagvideo!
Yes, the colors are important for proper operation...
:)

[@TheRealStructurer]

Can you call that a four wheel drive? 😉
Love your barebone wimsical contraptions. Do you have a display of all of them somewhere?
Thanks for sharing 👍🏼

[@popzct]

Hi TheRealStructurer,
Well, kind of? The wheels rotate when moving forward, and lock when moving backward, so.....
:)
Thank you so very much, I'm glad you enjoy them! And yes, my basement is full of almost all of the mechanisms I have created over the years.
And you are very welcome!

Hey, Red for Portside and Green for Starboard!

A fellow mariner! Very nice observation!

[@patricktowle2205]

Lovely project! I can't seem to find those female JST connectors that crimp onto the wire rather than to a PCB. Where did you source those?

[@popzct]

Hi patricktowle2205 and thank you so much!
The JST connectors I use I obtain from amazon which are "JST-PH 2.0 Male and Female Connector Cable", the link is www.amazon.com/gp/product/B07NWD5NTN/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Looking good. Now to scale up the legs so a body can be added. Might have to switch to a more powerful gearmotor. Or use the N20 motors with the right-angle drive shaft. Will the small travelers hold up to the added forces of the legs? We will see.

[@popzct]

Thanks John! I used the same self reversing screw components as the ones I posted hoping to inspire you to perform your magic! I did print the screw, travelers and legs in Tough PLA, and they all seem to handle quite a load.
Greg

[@Robothut]

Working a TT gearmotor version. Demo video load now. Walking action will try to be a classic ratchet linkage type since you have already done the linear shuffle walking design.

[@popzct]

@@Robothut I am truly anxious to see your results! I'm interested in a new 3D printer, and if yours can 3D print the screw and travelers, I may just have to buy one!
Greg

[@Robothut]

@@popzct video is up. The bambu lab A1 mini has no problem at all printing the screw and traveler parts.

[@ekaggrat]

you printed the drum vertically without supports ?

[@popzct]

Yes, that is correct.
