Chris, the time, effort, and choice to release this as an open source project is admirable! Your efforts will surely change the world! Thank you, sir, for your amazing work and sharing it with everyone! 🙏
Chris! My class of 7th and 8th graders just started building parts for the AR3 this week. Since we do some machining, we are doing all our own aluminum too. So far, their ideas include chess, sword fighting and a covid-safe concession stand. Looking forward to getting the electronics and hardware in and getting started. You've done an amazing job documenting this project.
Awesome, I look forward to seeing your students build and what applications they come up with. Keep me posted and please feel free to post the build on the forum. Thanks .
Amazing day we are living in of rapid pace. Companies still developing these arms in the tens of thousands while this awesome dude figures out how anyone on a budget can make one and gives out the info for free?! Bravo!
Thank you for the nice product, program, files, knowledge, perseverance AR2 completed, just upgrading now to AR3! I learn a lot with you Chris, thanks again!
Last night someone posted one of your videos on the LinuxCNC.org forum, i was pleasantly surprised, very nicely done and very reasonable prices for the parts, and all open source. Definitely deserves a lot of respect for being a usable robot, not just a gimmick. Thank you.
@@anninrobotics nothing in the specs about how much force it can push with. It would be nice to have data of force it can apply at different angles and extensions.
Your robots are the most advanced I have seen so far! I am following you for a long time and can’t wait to build one one day. Thank you so much for sharing! 😊
This is Amazing Chris! Love the way you are going about it, open sourcing everything, selling diy kits, & upgrading your passion project to benefit everyone! So Awesome! The world needs more of this! So Much Love Chris!
Amazing work here Chris, the world needs works like this to teach people and keep the younger generation interested in creating solutions rather than waiting for someone else to create them. Thank you for sharing tis with the world.
I might be the only other person selling an open source DIY 6dof robot arm. May I just say Well Done! Your arm is gorgeous and I wish you much success.
Chris very glad you have been as forth coming with your effort and hard work... its nice to know where the source for the Ar series originated. I have been watching from the beginning and look forward to seeing any new series. This time just dont give away free at least make china pay for a copy before they copy any new series as you deserve to get paid for the quality that you have built and people who have been inspired.
You good sir are amazing. I want to thank you for all your hard work and the willingness to open source it freely to the internet. I just came across this as I'm already looking towards my next project, I literally just finishing plugging in the test unit that will be going into my mini mill. This will go perfectly between 3D printers. Maybe 1 arm on tracks serving many printers would look far cooler then many at each printer....then again who wouldn't want an arm of robotic arms in their garage removing parts from printers at all hours of the night....
Great job on the video! I’m almost finished building my AR3 and I’ve learned so much from this experience, your instructions with all the pictures was super helpful and clear
Increíble este trabajo suyo y de gran aporte a la comunidad, de verdad impresionado, de todo lo que se puede hacer con la programación y la electrónica hoy en día, es fascinante esto y de admirar. FELICITACIONES de mi parte y sigue para adelante con estos proyectos

It takes a mountain of work to make this happen, and that’s not to overshadow your years of education, formal/informal. Thanks for helping the planet. YT doesn’t have a heart but just a thumbs up, so I did that, but here’s a ❤️ for you.
Hi Chris! I want to congrats you for your work and for all you did for the community. I am very happy to discovered people like you that develop this fantastic stuff and most important, you share it for free. Not because it’s free, because you are sharing knowledge that can be use for a lot of different things and can be improved and developed for a lot o different areas that probably you even think. I’m glad to see this and I wish you all the luck for your work!! Thanks 🙏🏽
Hey, im going to start building this right away! I'm a senior in high school and I am going to build this for my robotics class. I've been looking for an arm that is under 500$ and hopefully, I can use this to better understand the software control aspect and learn things like inverse kinematics! thanks :)
Stunning build with the AR3! The precision and versatility of a 6-axis robot are truly showcased here. Could you elaborate on the specific applications you see for this robot in a hobbyist or educational environment? Additionally, what programming languages and software tools did you use to control and customize its functions
When I'm watching your videos excited very much, Definitely I will build a small robotic arm after I saw your plenty of videos. Great work Chris Annin Sir, nice background music. Waiting for your upcoming videos. #TrueGenius one small suggestion When you are posting a video in description use #tags(#roboticarm #diyroboticarm #AR3roboticarm) then we will find your videos easily and easy to show others.
Incredible work. I totally need one in my life..... Not sure what for yet. But it can give me that 3rd arm and help me drink coffee while multi tasking :)
great video showcasing your project. i've been following for a while and im trying my darndest to come up with an excuse to lash out and start building one.
finally! a worthwhile project for my 3D printer instead of making drone parts. people are oblivious, the automation revolution is about to sweep over the planet like a tidal wave
@@paponchik You have very nice projects as well. Unfortunately most of your videos have commenting blocked and you don't share any material about your project :-/
@@victorfesto What do you mean that most of my videos are blocked? Are these videos not available in your country? I publish all the materials ( most of them ) on GRABCAD completely free of charge. Some I sell for a symbolic amount ( a few dollars). I use this money to make new projects. If you are interested in something - my mail is in the header of my channel-write, I will definitely share it with you.
Wow!!! Thank you so much sir! Would there be one day a bigger one available? I wish to have a robot on wheels, controllable from my phone through the internet
Really nice, I will think about getting a kit maybe someday. It's still a bit over my budget at the moment but if I maybe one day have a purpose for it I will definitely look into it. I'm wanting to know if it can do precision work? I don't plan on using loads heavier than 50~100grams. I see it can lift spool rolls and hold DSLR camera's, but that's not my intended use. What's important for me is repeatability and sub-mm precision.
Incredible Chris. Im following to you almost since 3 weeks. your projects are unbelievable. Im writing from Turkey. I love 6 axis robot arms and i want to make some kind of your arms but i dont know how can i code to robot arm? can you help me about how can code to arms? and i have question. why you don't build to your company and don't build your own 6 axis robot arms for industrial companies? :) thanks alot for what you teach to me. :)
Hello, thank you. I'd start with the kinematics and the videos I put out for that and then review all my source code, there's alot to go over but jump on the forum and feel free to ask questions and search the forum for answers. Thank you
Awesome , I can see all the effort going into this , firstly i'd like to thank you for starting an open platform where enthusiasts can work and collaborate to learn how robots work. Have you tried controlling this via a software such as RoboDK through which one can use the arm via serial , robodk postprocesses and talks with the microcontroller , this can be used for things like manufacturing and controlling the arm directly to 3d print ,etc,
Super cool, Chris. I remember the AR2 robot inspired me to write a whole program for forward and inverse kinematics. Then trying to figure out the Jacobian killed my progress! It's been really cool to watch the development of your robot. You mentioned you were a robotics systems engineer. Do you work on this type of robot fulltime?
Thank you, I work full time for House of Design Robotics where I program ABB robots and various automated systems. The AR2 and AR3 robot projects are what I do for fun in my spare time.
@@anninrobotics Hey Chris, thanks for the video, I'm a novice in Robotics, I have a ABB IRB 1600-5/1.45 Industrial robot, would this software work with this Robot?
Wow !!!! You had me at camera and filming this is amazing. Just have a few questions.(1) Only one size ? (2) Can the parts be upgradable like the motors/parts? (3) Does it have fast motion for high speed footage??
Hello, currently the robot is just the desktop size. the manual has some more specs on size as well as some other details. I do have a video that illustrates the different speed ranges the robot has but yes you can program it in percentage to go from very slow to its max speed.
Hi Chris! Great job man. I have a question. I saw the AR3 in aliexpress sold by several sellers from China. I know it's open source, and it's great to be able to build it at home, but sold by companies? Did you gave them the right to do so? What kind of license do you have?
It s way more complicated it s shown. A lot of work to build (see my recent Instagram updates). Work instruction is phenomenal, a lot of soldering. I m so excited to see how it s going to run. I am almost done.
Hi Chris, hope you going well i´ve got inspired by seeing your work and i want to design my own robot arm but i don´t know where to start, i think that i have to draw the robot arm as first step to know the weight and geometry and then do the cinematic and dynamic calculations to select the propper motor but i´m not really sure.
What an inspiring video, something really cool about seeing them move in sync - making the physical, squishy world precise and automated. I've learn so much in Cad, with programming and general design ideas when making a camera project for a friend. I find however soooooo much time has to be spent thinking, and re-doing ideas as you come across issues and more efficient ways of doing things. It's fun but takes a lot of time... I do love how by just lying in bed you can mentally improve a design. Do you have any ways that you shortcut straight to a good design first as I tend to find I over design things with high part counts and have to reduce them later. Do you have a workshop in the UK ? Would be cool to incorporate a short visit as part of a summer motorbike trip if Boris lets us out. Thank you, Ivan G-S
Hello, thank you for the comments. when I start with a new design I typically evaluate all the components that are off the shelf that I could possibly use and then start selecting the lowest cost versus the most practical and build my designs around those items and then test and redesign from there. No unfortunately I'm not in the UK, but if at some point in the future I am able to have a full size business and you are in the US I would love to have visitors.
Thank you! Great project! I wanted to start building this project, but when I saw some questions from guys who faced with some issues without answers, I afraid to start ). What is your next project?
Thank you for creating this robot Chris, I haven’t found a better design yet. I’m planning on building a bunch of AR3’s in a couple months to automate a goumet mushrooms production. Id be interested to know what the practical payload is. I need to lift up to 6kg, so I think I might have to make two of them cooperate. Is there a difference in strenth between 3D printed and alluminum? I‘ll write you a mail soon. Maybe you could help me out with some knowledge. Would be awesome!
Thank you, I look forward to your email, yes the payload for the printed version is reduced - I havnt actually pushed a printed one to its breaking point yet but I would estimate less than 1kg for a printed one.
Could you explain how to set a joint to a specific angel if the angle is not a multiple of the step angle or is there an Even smaller step than one singel step?
Currently I have arc moves and full circle moves. I'll have to think about spline moves, that would be cool to teach points along a spline and have the robot follow
Thank you but I'm not really that smart, just determined. It started with 3 motors taped to a board leaning how to control them, then an algorithm so all finish together, then made an arm and then worked on the math. Its overwhelming if you look at it as a whole but one step at a time builds up faster than you would think.
I’m not sure if you’ve implemented such a feature but it’d be sick if you had the walk through ability with your bot. It’s light enough and I think with your encoders it’s definitely viable. Just a thought!
super amazing, I am currently finishing mine. Do you have the link to the projects you are showing in your video? there are amazing examples of people controlling the robot through amazing interfaces such as tracking controllers, phones, joysticks. If you can provide info about those project it would be awesome so the community around this project can grow. keep up the good work!!
Hello, yes I have a playlist called ar2 user builds where I have a collection of videos from the other builds that I have found. There is also info and people posting on the forum which may help.
Awesome as usual my man. Thanks for doing this. Do have some kind of solid models available? I don't know of a way to machine aluminum parts from a mesh, and fusion360 does a poor job at converting meshes to solids ( haven't found anything that does it well).
@@anninrobotics Thanks. I have a hass mini mill. The dimensions x and y are 16x12. Before I run off and buy the models, off the top of your head, do you know if my mill is big enough to make these parts? I also have a 600mmx900mm router. Maybe I can make the arms from acrylic if they are too long for my mill.
They are planetary gears, they have a very small amount backlash but with the arm in compression it is vary accurate, a small amount of backlash to be expected with a low cost planetary option like this.
@@anninrobotics I see. Yeah, I can imagine that harmonic drives are not an option here. In any case it looks very solid, thanks for sharing all of this. Btw did you also calculated all the direct and inverse kinematics? that is a nightmare for 6dof robots!
cudos for making this open-source wow we will use this on our school building it will be a fun class project. Chris do u think ur arm could do CNC and 3d printing at some point in the future?
You sir. Oh my god. I dreamt about working with robots as a child. And now it is totally feasible. Thanks for your work.

I wonder what it’s like to be this smart
Thank you but I'm not really that smart, just determined. It started with 3 motors taped to a board leaning how to control them, then an algorithm so all finish together, then made an arm and then worked on the math. Its overwhelming if you look at it as a whole but one step at a time builds up faster than you would think.
Awesome!
Thank you
Thank you!

I’m not sure if you’ve implemented such a feature but it’d be sick if you had the walk through ability with your bot. It’s light enough and I think with your encoders it’s definitely viable. Just a thought!
?
super amazing, I am currently finishing mine. Do you have the link to the projects you are showing in your video? there are amazing examples of people controlling the robot through amazing interfaces such as tracking controllers, phones, joysticks. If you can provide info about those project it would be awesome so the community around this project can grow. keep up the good work!!
Hello, yes I have a playlist called ar2 user builds where I have a collection of videos from the other builds that I have found. There is also info and people posting on the forum which may help.
You should have waaaay more subscribers.
Thank you, im not sure how youtube recommends videos, i dont typically get as many views or subscribers for some reason.
Awesome as usual my man. Thanks for doing this.
Do have some kind of solid models available? I don't know of a way to machine aluminum parts from a mesh, and fusion360 does a poor job at converting meshes to solids ( haven't found anything that does it well).
Thank you very much. I do have the solidworks models on the robot kits page for a small fee that helps cover licensing and development stuff.
@@anninrobotics Thanks. I have a hass mini mill. The dimensions x and y are 16x12. Before I run off and buy the models, off the top of your head, do you know if my mill is big enough to make these parts?
I also have a 600mmx900mm router. Maybe I can make the arms from acrylic if they are too long for my mill.
Waw, I'm impressed ! Congratz with this awesome product !
Thanks!

you did a great job on this, i'm just looking at getting a 3d printer, what size bed would i need to build your robot?
Hello, thank you. a 200mm x 200mm bed will fit all the components for the robot.

Thanks soo much.
This is so cool!
Very nice project Chris. I was wondering, How did you solve the issue of gearbox backlash?
They are planetary gears, they have a very small amount backlash but with the arm in compression it is vary accurate, a small amount of backlash to be expected with a low cost planetary option like this.
@@anninrobotics I see. Yeah, I can imagine that harmonic drives are not an option here. In any case it looks very solid, thanks for sharing all of this. Btw did you also calculated all the direct and inverse kinematics? that is a nightmare for 6dof robots!
@@victorfesto yes I have done all those calculations, I have a series of videos on the kinematics on my channel that I put together on that.
nice work !
Awesome
Thank you
cudos for making this open-source wow we will use this on our school building it will be a fun class project.
Chris do u think ur arm could do CNC and 3d printing at some point in the future?
I am working on that. see the latest here czcams.com/video/KJFtruAHXoU/video.htmlsi=ZAIMZ1B3nSRURDdC
Uau
Show de bola!!!
