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?

That is some out-of-box designing right there! Bravo! 👏😊

Superb! 👍

nice work really whant to see it in action !!

Incredible torque

What specific motor are you using?

is that really the only/best way to join the two ends of the beaded cord - with soldering iron and cutting the balls in half? I'm wondering, how to do it with a metal one?

downgearing bldc motors is cutting edge for robotics field imo. however, rather than gears, I think pulley systems to downgear are the best route. quieter, can take up very low volume in total, can be made VERY small, can be VERY cheap to make. doing a lot of experimentation and design improvements on that area now. I recommend you look into this approach as an alternative.

i'll be home schooling my daughters. still a bit too young but teaching them cad like that is so cool. we'll have to do that for sure!

Awesome video! Please keep posting. I'm following :)

Questions Is the spring bend in spiral shape or in a 2D wave shape?

What motors did you use?

This is crazy bro lol my 3d prints keep failing at half the weight

Brother ur 🔥

Good idea.... 👍👍👍 Jossssss......mantulll

😮 ahhh ouai il vraiment bcp trop chaud le gars 😐

Paul this is great. I have been trying to find any additional info on Tesla's actuators. Are you tempted to integrate the motor and actuator in a subsequent iteration? Have you previously made 3D printed brushless motors?

hey great work !! is there a way to buy the controller ?

que impresionante

This is amazing! Well done! Any chance you would pen source this design?

Крутой редуктор, выидимо такого типа используется на робособаках

What is the purpose of the steel cable visible at 32sec?
