I am utterly fascinated by your work. Amazing stuff.

Awesome, very nice job !

Thanks for sharing 👍

The level of thought and execution here is fantastic; those cycloidal gearboxes are superb. The gear hobbing machine is put to good use; wire tendons are a good human analogy. Great result and video. Thanks.

I've built robots with cable tendons in the past and always had problems with them (cables can stretch, slip etc..) So it wasn't my first choice, but I think it's the best option here. I'll find out how well it works when the arm is attached.

I mean this in the most respectful and encouraging way anyone ever said something to show respect and encouragement: you are certifiable nuts and I love it!

Just remembered why I'm subscribed to this channel

Love it, this thing will be fantastic when it’s completed

Very clever analysis of the mechanics and very clever way of pouring the metal so you don't choke the hole. Man, the way you design this and how it works, this is just genius!

Stunning 👍😊👍

Awesome Build !!! Congratulations !! 👍🏻👍🏻👍🏻😎

Nice castings 👍

Some of them came out well, some had porosity/inclusions, Some I had to re-do. My sand casting technique is a bit rusty, I've not done this for quite a while.

I've seen a few 3D printed cycloidal gear boxes, but not a scratch built machined one, neat video, thanks!

This is actually the first cycloidal gearbox I've built. The design was largely dictated by the space it had to fit into and the fact it had to be hollow. It turned out fairly well, it does have a small amount of backlash but runs nice and smoothly.

Brilliant! Art in every respect! A modern-day Leonardo Da Vinci at work! Thank you for sharing, Andy.

Thank you for making that Dream true for so many people! So complex and welltought great work!

He did it ! He did it !!!! Again !!!! Yeeeeees !

Really sick man! Very excited for the next episode of this!

A wonderful project. Superbly made and very impressive!

That’s insanely good engineering!

its always a pleasure to see your work!!!!!

now this is a good notification to wake up to 💡

This thing is going to be a monster!

Anticipating the next installment! Have the notification bell on for it! Very nice work!

Wow. Great work dude. On the engineering and videography.

May i suggest you put the next and previous episode at the end of each video of this series?? GREAT WORK HERE.

I've been absolutely loving this project. Keep up the great work!

Наконец-то! Большое спасибо, автор!

Very awesome work. I love watching your videos!

beautiful. Monster of his business !!!!! 🤖🤖🤖

super good.. and fun to watch it

So glad your back, i really love this project. Thank you for documenting it for us :)

dayum dude, you never cease to amaze! i am absolutely certain that you could actually build a real terminator...a machinist terminator, not to destroy us, but to save us from improperly-hobbed gears. 🤣 peace

Super stuff!

Stunning. Please, keep going!

I am so grateful KZread introduced me to your work. I think I anticipate your builds even more than Clickspring’s Antikythera videos! 🥲

This is amazing. But I need to know. What did you do in a previous life? This isn't some run of the mill, "oh I watched a you tube video on it", you have some amazing knowledge behind it all. 5 stars!!

amazing again !

high salute sir,, very clever

Это будет шедевр ...👍

The next level job and the next future is robot

awesome man I love it!

Make sure you leave place for limit switches or rotary encoders, so it'll be easier to pose later when it's done.

I am really enjoying this build. your skills are stellar. I like these later ones where you have a running commentary. Would have been cool if you made the motor for the shoulder much stronger. You said 40nm is comparable to human. This is a T-800. Should be 10 times stronger than puny human. Maybe hook a diesel truck motor to it. :)

This is awesome

Thrilling progress and wonderful work in this episode. How did you calculate the design for the cycloidal drive? CAD plugin or?

@AndysMachines

2 жыл бұрын

I actually designed it in excel using a formula I found online, then just copied and pasted the values into a gcode file for machining. Only the cycloid discs were CNCed, everything else was done on a manual lathe/mill.

WOW

I love this project! Could you tell what is the weight of one shoulder? And how are you going to control the motors and joint position? And have you thought about using brashless motors?

@AndysMachines

4 ай бұрын

Thanks! Each shoulder unit weighs around 5kg. The motors or joints will have encoders attached for feedback of the position. Yes, I initially wanted to use brushless motors due to their better power/size ratio, unfortunately though they are much higher speed and lower torque than brushed motors meaning they need a bigger gear reduction so the advantage is lost.

Awesome

WHOA !!!!!!!!!!

brilliant work as always! fundraiser for CNC, waterjet or tool of choice? would serve you well.

Any milling machine you use.Do you use CAD sofware.

If you can completely automate this process, Skynet will be that much closer to ending the world

can you do a video clarifying the goal of this project please? Is this just a animatronic or will it be a full blown humanoid robot that will be capable of doing tasks and walking around etc?

@AndysMachines

Жыл бұрын

The goal hasn't changed since the start, though perhaps it will be time for an overview soon when I start putting all the individual pieces together. Yes it will be an autonomous robot, but it won't be able to 'walk' (refer to ep.1).

What's the backlash you managed to achieve on the cycloidal gearbox? Very curious how good a DIY cycloidal can be.

@AndysMachines

Жыл бұрын

I did measure the backlash and it came out to around 0.5°, though I deliberately cut the discs with some clearance to avoid binding as I was aiming for smooth running rather than low backlash. I'm sure it's possible to do better with DIY equipment, even some of the 3D printed ones I have seen have been pretty good.

I actually really wanted to use a brushless motor for this, but even the low KV ones have a much higher max. speed and much lower torque at low rpm, meaning I would need more gear reduction, since I want low speed and high torque. Brushed motors are more 80s anyway!

Супер !!! :)

Gday Andy, Have you done a video on you rolling machine used in this video?

What was the weight for whilst pouring the molten metal Andy?

@AndysMachines

To keep the top half of the mould in place. Aluminium is denser than sand so sometimes the top box can float on it and the metal will leak out of the sides.

It's a naturally occurring sand but it's actually a mixture of sand and clay (Bromsgrove greensand).

Id say grab a 3kw brushless motor and go into actual terminator strength territory. Though I think Cameron said it was actuated by high speed hydraulic servos in "real life".

I actually bought them, they weren't free, and this was many years ago (more than 10). There are many more better models available now and the ones I originally purchased may no longer be there. There are also many free models available on Thingiverse, but most of them seem to be copies of each other and all seem to have deliberate alterations made, perhaps to get around licensing/copyright laws.
