Hi! Do you still read comments? What is the best way to send you a question about the tail idea?

Very good idea. I like to use your idea for my robot arm as well. U reinforced the drive with bolts is cool💪. I decided on a 0.4cable rated 16lbs so using 4 o more on each side will surely have distributed load. The drive I prefer it stronger so 0.4can have smaller bend radius so M8 o M10 bolt will have the cable inside the thread. Thanks for sharing your idea❤

Human hand is faster, lighter, stronger and more silent at the same time. Natural vs artificial: four nil in favor of natural.

Why do you have 2 discs at the same orientation and 1 out of phase , why not just 2 discs with 180° out of phase

What kind of material 😮did you use on the gear... for them to not break

That clink makes it sound menacing

good!!

How do I adjust the eccentric radius? I get errors any time I deviate from 1mm?

Name of BLDC motor is what

have you published print files?

nice, got it. im trying to do exatly the same, this far i had it with strings but this is what im looking for.

abd your motors dont lock? how fid you achieve that?

So to make that linear i just need to make 50-100mm tube with pulleys to output one cable

this is really good, but i need linear input/output with the same design, the possibility to relax. I think with a few adjustements i could get that out you your system. Thank you very much!

hk0306 where do you buy these?

testing. many designs exist. but how does one test

turn the outer housing into a pully housing and anchor point x at base of structure

video is opensource. no wait ist ads paid

Paul what is the benefit of using 3 cams instead of one cam? What is the gear ratio?

This is very elegant robotic drive solution. Nicely done.

Love the video! Got a link to the BOM and Step files?

Any chance you can opensource the CAD files? I am curious to play around with it myself !

"it can hold up x kg of weight for x amount of hours consuming x watt hours"

How much energy does it consume per pound, static load over time

Our Hackerspace is starting a new robot arm project. Have any improvements been made in the last 3 years that we should be aware of before we begin? Thanks!

what size is the big bearing? 10mm x10mm? x OD and ID

That broke my brain a bit and was super awesome - nice work!

what type of screws did you use and is that a heat set piece that holds the outer cover together, thanks

Wow great work

you might have to increase mass on the legs to match the top

Nicely done! Hope we see the whole fish swims..

The small capstan that broke wouldn't be too difficult to reproduce in metal (if you know someone with access to a lathe), different friction coefficient but MUCH stronger. Very nice design.

Can you please share the cad file? thank you.

This is very clever and compact design. Make it alsmot full rotation. Thanks you for sharing it. Best of Best 3D printed reduction

Give me a place on which to stand, and I will move the earth.

Great design, but i don't think the steel cable will withstand multiple cycles of being wrapped around that thin rod (speaking from experience). Dyneema cord should have low enough stretch and enough tensile strength (especially since you have 4 cables).

Did this ever got open-sourced?

very nice research

Hey very great project 😊 can you plz tell me about the size of stepper motor you used

That is genius! I had to watch this about 10 times before i realized what you were doing with the 3 gears. Any problems with belt slippage under load?

Does it turn into a Cybertruck or something?

How did you know to build a replica of my left hand? JK, lol. Great work my friend! Very cool indeed! It looks like my left hand 100% though, no lie lol.

Bu dahice! Gerçekten çok etkilendim!

great job. that's actually pretty quiet. thought gears were loud as a rule. I'd almost accept that noise level in a robot for the most part. But complete silence is still the holy grail imo

Awesome

this is amazing!

Beautiful as usual - any problems with motor cooling?

Super cool Paul! As a designer of Optimus actuators, I am excited to see people innovating around our design. Looking forward to more updates.

How can you reduce vibration?
