No harmonic drive, only shitty servos, 3d printed plastic... Amazingly accurate

I'm impressed you managed to do this with servos. From my experience they aren't accurate to within a degree.

[WaynesStrangeBrain]

Nice!! I love squeezing out extra performance from not expensive hardware.

[YouMakeTech]

Impressive. Ultra stable, no oscillations! Thanks for sharing

[edoardoschnell]

Man, this is heavy flexing. Nice job.

Many pencil leads were harmed in the making of this video :)

The robot did what I tried to do for a whole hour as a kid in the 3rd grade

i am having a hard time understanding why someone would downvote this

Congratulations! I'm sure that took countless hours, blood, sweat and tears.

[Nandox]

Wow, really good accuracy if we look at the material used.
Great work done improving the hardware.

[ziad_jkhan]

Wow...I'm wondering what the maximum load is while maintaining that same amazing precision

[mheermance]

Really impressive achievement. Much better than my stock servo robots.

[executer]

Unbelievable. I´m deeply impressed. Great work. 👍👍👍

[morkovija]

That beat is perfectly matching for the upcoming robot uprising

[FB]

getting this precision with cheap servos, very impressive

[romwaite]

Great work! Would be awesome to see it make something using a 3d printing pen! Could be a freeform 3d printer

Impressively TRUE DIY and intuitive ☺️👌🏻👍🏻
