The easiest way to make a robot arm base
Вставка
- Опубліковано 14 жов 2024
- I'm designing and 3d printing a robotic arm to hold a camera and make graceful camera movements - like those Bolt Motion Control robot arms that everyone seems to use these days.
In this video I 3d print the base using eccentrically cycloidal gears!
These are the supplies I used:
NEMA 17 stepper: amzn.to/3gtK3Qd
Arduino Mega: amzn.to/3nx3Oui
5mm steel rod: amzn.to/3HMBGeV
Thin wall bearings: amzn.to/3gtYLqG
and: amzn.to/3H7JPZY
1.75mm PLA+ filament: amzn.to/3HvzVT5
The PTFE grease came from eBay - search for "50g silicone PTFE grease"
The accuracy and smoothness of these gears are so satisfying! Always a treat to see another mechanism of yours
Yeah, I love these gears - I knew I had to include them in the arm somewhere!
very interesting work. Thanks for sharing your knowledge
I did want to 😉👍
And I did also want to tell you that this is the smoothest low cost gear assembly for robot arms I have seen.
So well done. And beautifylly presented too.
thank you very much 😎
This is one of the smoothest DIY arms I’ve seen. Thanks for sharing the knowledge!
This one is turning out to be very interesting. Thanks for sharing 👍🏼
Thank you Mickael!
The production quality is amazing, great work! Love the pacing and content but would also fully support longer videos with more detail too. Cheers!
You make this all seem so easy. I've been shying away from attempting a 3D printed robot arm, but recently the urge is coming back to me and then I landed on your channel. Can't resist any longer!
Absolutely brilliant! More.
amazing work on stability
This is looking really good. One of the smoothest I've seen so far. Can't wait to build my own!
Thank you!
Absolutely wonderful!! I intend on using some of your principles in my own design!
Thank you! I'd love to see your design when it's ready!
@@roTechnic okay!!! I will reply to this thread with my video
@@constantinehelen9935 brilliant! Can’t wait!
Very interesting, congratulations. Definitly subscribing and waiting for the final result ;)
Thank you! Much appreciated.
Ur channel is top notch! Instant sub... beautiful engineering
Its turning out better and better as you go!! 😁
Thank you. And thanks for all the encouragement along the way!
Mate this is amazing, can't wait to see the next part!
Thanks Leo!
Brilliant video, as per usual!
Thank you! Cheers!
Keep it up mate, Love how simple thou supper helpful those videos of yours are
What a satisfying video. Am I crazy just for wanting to build one of these for no specific reason haha subscribed, looking forward to checking out the rest of your content!
haha, thank you. I have to admit that I wanted to build one and then had to work out a reason to make it!
Those bb's werent having any of it! I'd be interested in a video on how resilient those 3d printed bearings are.
Funny you should say that! I've already done one here: ua-cam.com/video/5YIZaJnER_k/v-deo.html
Indeed very smooth movement. At the same time a nice overview of your workshop ! Great !
Thanks Philip! I just wish I'd remembered to empty the bin!
Great job. I love your videos
And the obligatory comment.. Are you sharing your design? STL or OBJ files so we can print one for ourselves? Great project, have been following along with the cycloidal variants.. But, have you thought about ball bearing cycloidal drive?
thanks, yes the design will be shared once I have finished it - it’s a a constant state of flux at the moment!
maybe I should try out the ball bearing cycloid drive and do a video on it?
Nice and smooth!
Thanks!
Very nice!
Thanks!
Very cool, awesome work
Thank you very much!
Nice, I guess you could put some grease on the bearing balls to stop them from escaping
that’s a brilliant idea. I don’t know why I never thought of that!
@@roTechnic The bike shop teached me this trick when I needed a temporary solution for when my steering head bearing broke, just put a bunch of grease around it and place induvidual balls in the grease all around the tube head and they'll stay in place until assembling back the topcap!
That's a great tip! And I'll use it next time I strip down one of my bikes (which is WAY to frequently)
Do you do online training course if so I’d sign up 😭😭 aside from that amazing work I’m still trying to picture and understand more about the actuators and gears and how well they would need to be together in some cases and situations.
mMoooore DOF's!🤤
and there’s even more coming soon!
nice job thanks
nice
Thanks
How will we handle the software part, which is the most important part?
I have a giant favor to ask for myself and perhaps on behalf of all the new subscribers landing on your videos from over the pond. Quite a good number of the amazon links are no longer available. How possible is it to regenerate the links for the non-3d-printed accessories?
In terms of algorithmic design ie. Inverse Kinematics, what are the best places to get started?
If it's for robot arms, then I'd probably start by reading some of the guides for the MoveIt project moveit.ros.org/
@@roTechnic Nice, I'll take a look at that now - it would be for robot arms. Is this what you have used / planning on using for your robot as well?
@@aiyushg1769 yep. At the moment it's just using some quick and dirty arduino code and inverse kinematics I figured out in a previous video. But when I've got the hardware done I want to get it running ROS and MoveIt.
I want to make this robot arm, but I cannot divide the Step assembly parts in Solidwork. Could you please share the step file of this robot arm in parts?
tres beau la denture hélicoidale . en chevron l efffort axiale est réduit
Nice video !
Thanks!
Any reason you use a blowtorch for the heat set inserts and not just a soldering iron?
yes, both my soldering irons decided to die at the same time!
@@roTechnic That is really unlucky, make sure you buy three next time incase two fail again.
Can you please share the files?
I would love to give it some thought and try to improve it 😜
files are linked in the next video's description!
Would you be willing to share the step or stl files for this base?

@@roTechnic ty so much
i am chutiya
yes you are
ok thank you
welcome boss
