Yes... just... yes. Make these, someone, please. Absolutely awesome!

So good, why is this not commercialized?

[@theredstormer8078]

It's probably either too new of a technology or too hard to mass produce, but I'm no expert.

Omg so good….. Insanely compact assembly

I've been looking for things like this for a long time, where can I find them? how much for some of them?

[@noatreiman]

It looks they are still in the research phase? The paper associated with this video came out in 2021 ris.utwente.nl/ws/portalfiles/portal/256839289/MultiMotor_RA_L_AuthorCopy.pdf

Is this video speeded up

이거 디게 간단한 원리임. 0:06 선이 많은걸 보면서 대부분 금방 눈치 챗을거임.
