That elliptical friction drive thing is called a harmonic drive, used to get very high gear reductions in a very small form factor. Google them, they're a ton of fun. (Warning, haven't seen the entire video at the time of this comment, maybe it was mentioned in the video itself.)
This video could be way more educational. Instead of pulling one part after another out of the bucket and blabbering some gibberish about that (as stated those arent friction drives but harmonic drive gears) it would be better to show everything working together and state out some of the fine details. Also for showcasing it you could saw out part of the frame elements of the wrist and assemble everything back together, so that the viewer can peak at the mechanism in assembled form.
*sigh* 7:21 Thinking back Im pretty sure the hotel cleaning ladies thought that it was some part to the bed that fell off. I had it on the dresser the day after I visited and I never could find it again. :'( I still have the other one on my dresser at home on the shelf with all my cool trinkets. Who knows maybe I'll find it in the bottom of the ski bag someday.
Saturn 5 never exploded thanks to over engineering. Please go to details what makes KUKA so good. From shape of the gear teeth to the shape of cast parts of the arm. What makes them low noise and stiff. Hopefully new generation of mechanical engineers will pay attention to this UA-cam channel. Universities are behind on practical education.
Jeeze this guy has no respect for engineering, NO respect I say! A piece of metal is not machined to microns and cost upwards of thousands of dollars. Have some respect.
What you are calling a friction drive, is a Harmonic Drive, two totally different things/ systems
That HUGE banner across the bottom of the video obscures what's trying to be shown.
Harmonic drive, NOT friction drive... !
no, no, it's a hyper drive!
Harmonic yes - called a "strain wave gear".

This is harmonic drive?
Yes.
Yes, its a Harmonic Drivers, or strain-wave gearing.
when is your machine shop series coming up again We are waiting for the return for forever.

If they were that clever they wouldn't be posting you tube videos... the paradox in this space.

Hanzhen harmonic gear drive , robot joint gear , over 30 years experience
Ditch the address watermark at the bottom. That is annoying as hell and blocks some of what you are showing us.
how does axis 4,5 and 6 function when axis 3 is smack in the middle of their path??
I think you meant the cage of the bearing, the race is not what holds the balls in place. They roll in between each the race
How about mounting it back?
What you are calling a "friction drive" should in fact be called a "harmonic drive". Wikipedia the 2 terms to see the difference.
Do you have any video about inside of 1,2,3 axis ?

hi Richard Piatek, please i want speak with you about robot arm for contact with me, send me your email by this mail: hoummani.mehdi@gmail.com Thanks
thanks, i want learn more about robot arm, any info??. Website, material to learn about, or any type of simulation software
Hi Fatmachiniste, me too i learn about robot arm we can help each other, if you want contact me sen me message by this email: hoummani.mehdi@gmail.com
cool
Friction drive? What?
So?
