Ive known and treasured Legos all my life. Yet I keep being suprised at how rediculously well designed every single Lego piece is and thus allows stuff like this here. Best "Toy" in the history of humanity.

[@Ragondarknes]

Very interesting. I will theorise here that because the joints are at 25 degrees angle, instead of 22.5 (Which would be half of 45, or 1/8th of a 360 circle), this is why some movements or positions look like they're not quite straight. But obviously you're limited in what angle you can make by the lego parts themselves.

[@Retrolizer]

You would be surprised

[@LoneStarr1979]

As this mechanism is used as a thrust vectoring nozzle for a VTOL jet, I guess the 25° ( --> "overbending") are intentional. This gives the aircraft somecontrol authority in every direction when hovering.

[@Chevyman3030]

I love how it gives off TF3:DOTM driller vibes and how it moves so organically you are truly ahead of your time when you build such amazing creations you've made

It would also be useful in factories as a way of picking up items and immediately transferring them

[@strictnonconformist7369]

A fun thought: add one more module, make it a bit sturdier, carefully account for balance and have batteries, and you’ve got yourself an interesting Slinkybot that, when enclosed with a flexible shell, may work better as a Mars explorer because it can’t get wheels buried in the sand. It may help to change the number of degrees for each segment, and not being constrained to Legos, that’d be easy enough.

Will the cables get all twisted up if you keep rotating the same way or is there a way to prevent that?

[@esynthesisman]

I never thought of using this structure again. It's amazing.

[@Skeptical_Numbat]

Brilliant work! It's such a fascinating design. A way of "bending" a joint without having a hinge which gives robots an incredibly wide degree of motion. There are analoguous structures which have evolved in the legs of insects: joints which only contain rotational segments, but appear to bend much like our elbows. It would be pretty odd looking if humans had joints similar to this. Could you imagine how bizarre something as commonplace as _Walking_ would look..!?

[@GerbenWijnja]

I never knew these Lego stepper motors are so accurate! Very cool project.

[@MikkoRantalainen]

Interesting structure. It would have been interesting to have all the motors in the base and use universal joints or CVT joints to run all the parts. That would allow unlimited movements without thinking about wire twisting.
