We’ve all seen Doctor Otto Octavius or Doc Ock, in the Spiderman comics and movies. Dock Ock has four tentacles and four of his own limbs, so that makes nine in total, and that’s the same as an octopus.
Lots of cosplayers have made Dock Ock cosplays, including Adam Savage, although mostly those tentacles are in fixed positions or supported with strings. So this time I’m going to try a different approach, using six actuators in each segment of the tentacle.

Ah yes 4+4=9
What I think is especially fun about this, is that the tentacles from the movies also have a triangular cross section and seeing how this moves, this might actually be the way to go about it
Ahh yess click bait with title bait
9 in total? Umm... 🤔
4+4=8, actually. Did you really get an F in maths, because that's what it looks like to me.
For the second prototype feel like a smaller version of each segment to reduce the strain on the base might make it look even more like a real tentacle arm.
Four plus four is nine now?
can we appreciate how impressive real tentacles from octopus and squid and such are. To have the degree of flexibilty while still retaining strength is ceaselessly amazing
just don't give it a knife or you'll never get it turned off
"... Dock Ock has four tentacles and four of his own limbs, so that makes nine in total ... " written in the video description. But why nine?
Really great video! And thank you for mentioning my work!
Further showing that Dr. Octavious' fusion demonstration really glossed over the robotics miracle of his tentacles. Great video, really can't wait for the next version!
Amount of servos this guy uses in his projects is mad. Respect ++
Implementing inverse kinematics for the end effector plate would be a very interesting follow-up!!!
That's really cool!!
Look into using flexures rather than pivots. It should be lighter, and the springiness will give a lot of inherent structural integrity. I've had good results combining PETG with spring-steel inserts and elastic.
Doc Ock quite often uses his lower tentacles for stability, so that might help with the weight issue. Also, I would say it's already a work of art, even sans LEDs.

This is one of the coolest projects you've done in quite some time! Love it! Keep it up
Could you change the kinematic model such that each segment starts moving a bit before the one below? I think that might give it a slightly more organic feel, like it's curling into each movement rather than leaning.
