It's really cool to see a machine move so organically... almost as though it's alive.

@ogelpeace4610 Рік тому

@Ragondarknes Рік тому

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 Рік тому

You would be surprised

@LoneStarr1979 Рік тому

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.

@maxwhite4732 Рік тому

These crazy contraptions never cease to amaze me. I can't wait to see this as a great ball contraption. It would be awesome if it could pick up the balls and then 'eat' them so they fall through the middle and out the bottom like some sort of worm creature.

@alexharkler Рік тому

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

@wanderer3757 Рік тому

I think he marked the joints with triangle stickers(?) for it.

@Jorazon1 Рік тому

I think it would be possible to splice a slip ring into the ev3 cables which would allow unlimited rotation.

@MikkoRantalainen Рік тому

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.

@GJBricks Рік тому

That’s amazing! Everything down to the round tiles as rollers. Incredible! Great work!

@strictnonconformist7369 Рік тому

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.

@ogelpeace4610 Рік тому

@didiwin78 Рік тому

its like a air duct joint, but motorized. very neat!

@_ninthRing_ Рік тому

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..!?
