3D printed self-excited actuators and robot applications

Suzumori Endo Lab, Tokyo Tech has developed self-excited pneumatic actuators that can be integrally molded by a 3D printer. These actuators use the “automatic flow path switching mechanism” we have devised.

You Guys are absolutely amazing! This is soooo freaking stunning, what you create! I Hope sooo much, that your Robots patented and you have a Sponsor for your Projects already. 😍👍

Those soft actuators at the end of the video are SICK

Cool sprinklers, very funny, would buy

Where are you my friend We've been waiting for so long

[@bearnaff9387]

On the soft oscillators, could you run a multi-frequency unit by changing the length of freely moving outer shell. If you used s more conventional motor to slide a sleeve up and down the soft arm, wouldn't the frequency of oscillations go up as the free length decreased?

0:35 I guess this is like a more efficient pinwheel in a weird way? kindof?

[@thorstendornbach3976]

this looks promising, I just don't know jet for what :D

[@tinkmarshino]

more interesting ideas.. Now, how can you incorporation that into the muscles of a robot along with what you already have going? Many good ideas are converging into one grand complex notion..

Really useful new d!ldo technologies 😅

Lol

I heard that too much "self-exciting" makes you blind, and grow hair in your palms...
