The most advanced 3D printer robot (refreshing my 4y old design)

- I have decided to redesigning my four years old project - 7DoF brushless robot arm. I really love this design so I would like to complete it (before I had only 5 axis out of 7).
The NVIDIA Jetson Nano Developer Kit raffle ended on August 28, 2023.

I don't know if this has been thought of or covered before, but an accelerometer to provide position feedback at the arm might allow it to compensate for all the compliance in the actuatror plus any flex in the beam.
So cool!
There's a lot of elegant design in this. Very impressive 👍
Can you recommend any beginner friendly mini/small robot arm projects to help understand the basics/foundation, thanks 🙏🏻
The name of the CAD software is Shapr3D.
Thank you. I listened 5 times and gave up 😅
It's a small thing but I like that belt tensioner. No need for an adjustable mechanism when you can just print a new part for next to nothing. There's probably a bunch of other design paradigms that need to be updated for new technology like this.
@Badspot : There is a temptation to use a sliding or eccentric tensioner... my experience is that they could be a weak spot, and probably become a source of annoyance.
wow, really nice structure overall. Maybe try to reinforce the top plate with a screwed or slotted profile...
By the way, what would be the total cost to have it fully operating, considering controller and claw?
Супер! Когда выйду на пенсию, надеюсь, так же буду проводить время.
I already was a subscriber since your over engineering of the eye, truly fun to see all these things you are making and giving back to the community.
If you have time please make a video on how you simulate your robots in Nvidia Isaac and how it differs from gazebo. Or the reason you jumped to shaprd CAD instead of fusion 360. What do you recommend us beginner Robotics fans to use. Personally I have used fusion 360, solidworks and inventor and sometimes shaprd on my ipad. But to be honest I like solidworks and inventor just a bit better. The other two work but just a bit different. Good luck with the raffle, I entered if I get it I will make youtube video on it and write blogs on how to run simple ros projects on it and also dip my toes into Isaac sim.
This is quite cool after the long wait :)
Nice build!
Any reason you switched out of Fusion? How did you migrate the design while keeping all the sketch and projections intact?
The Odrives can use Canbus and are able to be daisy changed together. I'm just wondering why you did not use Odrives this time?
Great Channel but... I can't think of many/ (any?) diy robots that are very useful and easy to program for different task on a day to day basis.
I made one simple one, but it's an easy task that i does and not critical. I think the hardware , though not easy, is easier than creating an interface for the user to accomplish useful tasks.
Nice. Can I know what motor you use?
Cool!
You switched from Fusion 360 to which 3D program?
Shapr3D
I know it will be a amazing video
Hello. I would like to know what kind of bearings are used in your design?
8:30 Looks like the top plate was bending, maybe that caused the misalignment?
Yes! You absolutely right!!! The grey parts are flat, and thus can be replaced with waterjet cutted aluminum parts (cheap), this can help.
Thank you. I have not notice this before!
He: "Why is it not breaking?"
Me: "because you want it to break"
if someone would like to replicate your designs at home, do you have it somewhere (github, etc.?) or only information is via your youtube videos ?
Компактненько.
Awesome ❤🇧🇷😊👍👏👏👏👏
What motor is that?
Awesome project, thanks for sharing 👍
Thanks for watching!
molten aluminum 👌
Time flies

kinda wild how odrive dropped the ball and now everyone uses mjbots now lol
what's funny about that
mhd true dc motor, ie radial current, two steel/metal surfaces, rolling ball bearings as the current pathway, vertical magnetic field below insulated, a thrust bearing socket on the bearings top side
also specialization means that you dont use your own parts, in something you would like to use yourself, ie specialization is without sense
there is no use for specialist, and trade, as diy is better, so that none does nonsense for others
science alone does not help anyone, do it like you would use it yourself, and not for selling in any way
then it might be useful actually somehow
forced trading is not useful
8:50 yeaaaaa now i bet you're thinking back to how you said "wow this is heavy" earlier in the video. You apparently designed it WAY over-spec, and it should have been lighter.
a comment!
