HTML-код
- Опубликовано: 17 авг 2024
- I tested my 3D printed DIY robot arm. And it has outstanding capabilities, comparable with some industrial robotic arms!
1. The precision of the robot is around 0.1mm.
2. The maximum speed is around 5.9cm/sec.
3. The maximum payload is around 150-200g.
All the files necessary for the build of this robot is on GitHub. Here is the link github.com/Sky...

5 years on and this is still REALLY impressive precision. Fabulous work Sir!
Thank you for such kind words.
I woke up this morning thinking I was a smart person.
Then I watched your video and now I feel like Forest Gump...lol...
Well done.
You are a creative genius.
Thank you for sharing your beautiful mind.
Oh my god, this is the best DIY robotic arm! its movement and design are fascinating!
Thank you very much. I love your comment!
Wow! This is one of the best DIY robotic arms I have seen! The accuracy is fantastic! I am looking forward to your build video!
Thank you! I am gathering parts for the build video :)
Yea it is
Самое интересное, что такой акцент я лучше воспринимаю на слух))) но в любом случае отличные видео, спасибо автору
Огромнейшее спасибо за публикацию всего этого дела на гитхабе!
Спасибо за положительный комментарий!
outstanding work on that arm, all the hardware you design is a level above and beyond every body elses
your channels deserves so much more recognition
The movement looks so stable and smooth! Very nice
I really like the look and how smooth it moves. Awesome accuracy
You did a really great job on this one. I haven't seen all of your robots yet, but this is my favorite one so far. I am considering trying to make this one.
Congratulations!!! fantastic job, incredible movements and nice accuracy, after more than one year to decide what robot to assembly, finally I decided your robot arm, when you plan to publish stl's files and assembly videos?
Thank you very much for the this kind comment! I've already published the STL files on my GitHub page (github.com/SkyentificGit/SmallRobotArm). Also on my channel you can find two build videos of this robot. This week I will publish the video about GitHub page (now I have all the necessary files for building on this page). And in the next couple of weeks I will continue with the assembly videos.
Thank you, I will add after reviewing the information you have provided I will say you have done an outstanding job. Best of luck to you. Cheers!
robots with good music :)

Great work! Thank you for publishing. I would like to build if you publish the STL and other documentation as an open source.
I will do this. I plan to do this before Christmas. I am going to revise the plans and make a build video. As soon as I will do this I will publish all STL. I just need to order some parts for this.
@@Skyentific I look forward to it. I wish you success !
@@privatconcul911 How did it go? : )
this is best open sourced robotic arm in the world.
Thank you!
Great job, I liked it, keep on.
Thank you!
Жесткая... Отличная работа!
Всем добра!
the best robotic arm i have ever seen Great
you are a gem...!
ya estoy armando el mio propio muchas gracias
Proper robotics YtB channel 👍🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
thank you, this just can make a diy fabrication revolution with continuous fiber 3d printing and RFWT robot filament winding technique ....
thanks again
Extremely impressive to be getting accuracies down to a few tenths, It would be interesting to see if the first test having higher comparable variance has something to do with the arm being just turned on and experiencing thermal expansion and if it would be better after having already warmed up.
Тесен мир, Геннадий :-))) Привет от мифиста!
неожиданно! :) привет!
@@Skyentific не знаю, есть ли тут личка, если что - приходи в телеграм @Neonyn, пообщаемся :-)
Отличная работа!!
Looks very nice
Awesome!
Thanks!
I really like this design, it does have a lot of exposure for industrial use (belts and such) still amazing. Let's see it scaled up 50%
Excellent video!!!!!!!!
I'm impressed by your work Sir, and I enjoy your humor. How would you compare your own robot arm with the "inexpensive" ones you are testing. I ask because I'm thinking of duplicating your design as a way of learning what matters.
Awesome, thanks.
Фантастика! Огромная работа!
Good work. Keep it up.
excellent job
Thank you!
Stunning project, and very satisfying results. In your conclusion, at 10:54, you mention "5th axis skipping" is this the belt skipping teeth, or the stepper skipping steps? Many thanks, liked and subscribed.
Thank you for your support. It was stepper motor skipping steps. It has small Nema 11, which is not very powerful.
Nice arm bro!
How to connect and control the robot with ROBODK? I've built the robot, but I can't program it.
What materials did you use for this robotic arms ? The move looks incredibly smooth , and I can’t even sound a motor (which usually loud on any robotic arm) . Outstanding work !!
Подписался. Смотрю видео дальше)
Thank you!
Incredible. Can you make a DIY tutorial on how to build one? Does it use any kind of encoder? Is it DC stepper or AC servo driven?
simply awesome
Fantástico. Muito bem concebido, bem desenhado. Parabéns!!!
What small 6 axis robot arm will hook hook up to the Intel Compute Stick 2 the USB flash drive stick. A affordable one for home use though. I had a 6 axis robot before but want one that all have to do is plug this flash drive in and all I have to do is program it.
Very impressive 👍
Cool engineering!!
Very nice robot you've built. Regarding accuracy of industrial robot arms such as Kuka, ABB, Fanuc etc isn't that great anyways, at 2m movement they can be off by several mm. With absolute accuracy they generally specify 0.5mm. They have very good repeatability though especially considering the payloads they handle. Your's seem to have great repeatability too.
That NEMA 23 with 1Nm of torque and a lever of 30cm should be able to lift a few kilos on it's own without the gear reduction
Yeah, but thats not the stepper that was losing steps, he uses nema 11 and 8 steppers in other axis
How?! 1Nm = 0.1 kg.m. On 30cm arm it can lift only 300grams, and this is at maximum torque. This means that the motor will heat up fast, and would not be able to work continuously.
@@Skyentific sorry my mistake, but with your belt reduction it should be able to lift about 1kg much more than you've demonstrated in the video, anyway how is the backlash on that robot arm?
does this arm inverse knematics model? could be controlled with ROS or moveit?
You are very very the best awesome boy who i ever seen. Your contribution is fundamental for the next future. Is this a bubble market? I don't know. But, remember Apple.
Thank you...
Terrific!
How to use this arm as a 3D printer? eagerly waiting for such video.. @Skyentific
Same, I'm reluctant to buy a 3D printer if I can also use something more general
Is there a way to have access to the drawings and designs, I would like to duplicate that arm that is just the most amazing I´ve ever seen
Check the description; all files seem to be on the linked github page.
Ciao, complimenti per il progetto, mi ha affascinato da subito, sto terminando la stampa di tutti i pezzi, solo che trovo una grande difficoltà nel reperire tutte le cinghie, pulegge e cuscinetti necessari. Non sarebbe una cattiva idea se mettessi a disposizione un kit pronto per l'acquisto di tutte le parti meccaniche. O magari dei link diretti per l'acquisto....spero tu possa aiutarmi, complimenti ancora, Sabino.
I'm thinking about building this, is there a video of you wiring it up?
do you think it would be possible to mount a hot end extruder on this and make it a 3D printer?
I would like to buy it, would you consider selling robot arms as some point. If the price is affordable I am sure you will have lot of customers
Возможно у Вас приобрести комплект под самостоятельную сборку?
Is there a way to increase the payload in this robotic arm without bigger changes? I would love to have around 1kg = 5x higher. Do you think there is a way to make it with your model? And i dont know if i missed it, but can you tell how much the robotic arm would costs around? And how much infill do you use on the 3d printed parts?
I think the maximum, what is possible to do with current design, is to add active cooling and increase the current on the motors. But this is not going to increase the payload 5 times. A think it could increase the payload by 50% maximum.
I have an idea for the next robot arm. I plan to use brushless motors. And I hope to have the payload around 2kg. I plan to start building it this month, but I cannot tell exactly how long it will take to develop it. I hope to finish it by July.
For the plastic parts I use 50% infill. About the cost it is around 400 dollars, and this price does not include 3D printed parts, does not include bolts and nuts, and other small components and it does not include the shipping costs. I have GitHub page for this project and there you can find a bill of material with approximate prices. github.com/SkyentificGit/SmallRobotArm
@@Skyentifici i know exactly what you mean with "you cant tell how long it will take to develope" :-) I am in the team of werbewunder here on youtube and we also have the same way to think :-) Maybe one question more, why do you plan to go only for 2kg payload if you calculated before the needed motors for the 7kg KUCA model? Too high costs or what is the reason, because in your video i think you talked something around 200 euros or dollars for the motors. Thanks a lot for your answers!
@@Skyentific so the costs are near only for the motors? Thanks for your answer for the infill! Its ABS or?
This is cost for motors, drivers, belts, carbon fibre parts, bearings and electronics. My first robot (yellow one) made out of PLA. And the last one (orange one) is made out of PETG. I tried to use ABS before, but I had bad experience with it, and now I try to avoid it.
ок, я подсел)
Does anyone know what the name of the test stand with the button is called at 2:41? Any help would be appreciated, thanks!
Hello,
I am trying to build my own robotic arm, the design is different but I am using almoat the same motors and planing to use the TMC 2209. Could you please recommend a genuine place to buy them? Also, if you think there is a better driver for me, your suggestion will be really appreciated.
Great build! How much could you build another now that you know exactly what you need?
Great job! What is current on those steppers? Btw looked into github for electronics, any reason TMC2208 is not an option?
will you post the files to this project/make a tutorial on how to make it?
It is already done. All the video on my channel and also I put all the files on the GitHub page. This is the first build video: ruclips.net/video/oFCUw1pXlnA/видео.html . In description to this video you can find the link to GitHub page.
Skyentific you’re a saint. Hands down.
Anyone have a “clean” CNC file for carbon fiber pieces cutting ? I can’t use project DXF files. I really appreciate. Many thanks
8:48 Can you fix the auto-generated captions here? Seems like RUclips missed some speech.
Hello again! I have a few questions if you don't mind... Have you made a robotic arm that is strong enough to hold the weight of a DSLR digital camera? And have you used any ODrive components on an arm? Thanks!
please skyentific. I want to learn to create the code to move 6 axis at same time. I want to use ac servomotors. pulse direction. please please can you recommend me a book to create the code to send pulses to 6 motors at same time. please.I have the inverse kinematics. but the problem is how to create the code for motion control please.
Could this machine perform gcode? I would like to build it but mostly have mechanical knowledge.
Does it do joint moves or can it move the tool linearly?
Excellent project, unfortunately sourcing parts seems to be more difficult than expected, aborting to get one!! very sad! belts are not available, bearings also difficult
Good project but it seems to me that the motors are taken with 5 exceeding. Would be enough in two smaller. I have these stand on the CNC machine weighing 200 kilograms.
Очень очень круто, какая себестоимость этого робота ? Я бы хотел купить такую игрушку 😁. Не думали о производстве и продажи ???
I interested to make one 😁
Great! Thank you for your comment. I ordered the parts for the second robotic arm. As soon as I will get the parts I will make video about how to assemble this robot and I will publish the STL files.
@@Skyentific and me too, please)
Hi, I am a electronics enthusiast and I was wondering if you sell your robot arm. I have ALS, I need a robot arm that I can program to feed me...
Awesome robot. Do you plan to make the plans and STL available?
Yes. I would like to modify some parts (there are some bugs). And after I will made it open source. May be I will do this in one of the next videos.
I'd be interested to know if you could put an extruder on the arm and see if you can make it do some basic 3d prints ;)
This is super good idea to try!
@@Skyentificgreat!!!!!
@Skyentific Hello, I'm from Argentina, it's an incredible job, I'd like to do it !!, I'm consulting you use to control it? What plate and drivers? in my channel you can see one that I did but I can not control 5/6 engines ... thanks for such a spectacular project, I will wait for you to live the parts to print them.
Русский акцент)
И по-этому не нужны титры и паузы, всё здорово для меня, как русака - понятно)))
What programming used in robotics
Take into respect an accumulated accuracy for all three axis
can you give the list of all the motors that you used
Как то не очень возвращаемость проверял. Надо бы после каждого замера, чтоб рука по всем осям подвигалась с максимальной амплитудой, наглядней было бы.
I think you are right. It should be also interesting to test this under the load. Maybe this is for the next time.
Very nice. How much time did it take to develop?
Good question. I think It took me two or three full months, spread over half year period. This is my most complicated project yet.
Considering how much effort is required for this kind of projects, I think that's pretty fast! Can you recommend some sources of information that would help me to get into robot design, especially for 3D printing and mechanics? Perhaps some books or tutorials?
Would it be possible to increase the speed in github? Say, double the speed? 10cm/sec?
OMG best robotic arm !! What you use to pilot the arm ?
I wrote the program for Arduino. It is not very optimised, but it works. I am going to make my next video about this program.
You should just put something capacitive on the end and have it hit the button on the ipad LOL
So how to build me one?
Please create video with create robot R2D2 1:1
Should you perform test of accuracy/repeatability UNDER load, please...
Nice idea. I defiantly should do this, especially for repeatability.
Also, using different paths and acceleration curves to the same destination point in 3D may be interesting. Honestly, it should be no big expectations with open loop control, even with this big steppers and carbon stiffeners...
thelittlebigoneru, what do you mean by this? 3D printers works just fine in open loop control. And with Trinamic drivers it is possible to detect collisions and skipped steps. So, with the Trinamic drivers this is not completely open loop.
This robotic arm is designed to be affordable in price. And it was not designed to have all the possible features.
You are welcome to take my design and improve it. :)
3D printers have limited and constant 'payload' for its drives. With Trinamic, it will be a way better. But, now even BLDC servo is not rocket science. Enabling technology is single-chip hall-based rotary encoders with absolute angle readout and 16-bit resolution.
thelittlebigoneru, please, just do it. I will be truly happy to see the result. ;) But do not forget to open source your project.
true soviet engineering comrade
Yes!
good!
Thank you!
9:30 subtitles
Where to purchase this?
I thought to robot was massive untill i noticed your leg at 1:40 shoot
Why does it skip steps when you increase the speed ?
It is pretty common for stepper motors - they cannot apply the same torque at high speeds. Also there can be problems with pulse generators - for high speed you need very high frequency pulse with low jitter.
Also Arduino sketch on github may have some problems. Although Arduino can produce low jitter pulse, it requires some special programming methods, which 3d printer firmware like Marlin uses (not just Arduino delays everywhere).
