This project is so amazing! It makes me so happy to see a talented engineer like you making such a big impact on students, kids, and even industry. Nice job!
Man this is the coolest thing I have seen. Thanks so much for sharing this with everyone. This project is actually very important. With AI getting better and better we will need open source robots for people to be able to start businesses so they can keep up and stay competitive.
I understand what you’ve done here. It’s extraordinary. For one guy to finish this as a DIY kit goes approaches genius on several levels. What a wonderful learning experience for those who are fortunate enough to be involved in assembling and then experimenting with this. Thank you.
Just a few days ago I was wondering why there wasn't an easier way to get dishes from the sink to the dishwasher and viola! I'm glad someone is working on that problem. Thanks for sharing your work. If I ever build a robot arm this looks like a perfect fit for the types of things I would do.
This is one of the best projects I’ve seen in a very long time. Thank you so much for doing all the work to create this. You really make a difference in a lot of our lives. Bravo!
Amazing! This is by far the best open source arm assembly I've ever seen. Your knowledge in the field clearly shows in how refined and solid this is. Can't wait to try and build one!
I've started programming Fanuc robots for work and after seeing how fun they are, I had the thought that somewhere somebody has to be making 3D printed desktop versions of these things. I didn't expect to find someone taking it to this level though, nice job!
I can remember when i was searching 5 years ago for this kind of robot arm... and the tolerances were not good enough or the prices too high... you did a really great job to give even private people the possibility to use it for their daily jobs or small companies.
I, as an engineer, really admire your work! I am also jealous because i used to work on kinematics and then i started to design a programming software but it was too difficult and i didn't have enough money to build a robot because of my unemployment. Now i have money and more knowledge but no time :D But i am so happy for that someone actually does this. Best wishes!
Chris I'm trying to build a parallel cable robot to 3D print houses. How do the kinematics get incorporated into the programing? In the firmware or the slicer? Will I need custom g code?
Just stumbled onto your channel and WOW!!!! Your robot arms are impressive to say the least. I have a project I am just starting that will be using an arm. Depending on how it goes I hope to build something like this robot arm. I am subscribed and will be watching for your future vids. Thanks so much for sharing this project.
Thank you. I do have a complete manual for the robot at www.anninrobotics.com/downloads and there is also a tutorials page with a number of videos. Let me know if you have any questions.
first of all congrats to you for building this wonderful project. Your projects are very helpful to learn. and thanks a lot for sharing your knowledge and ideas for free.
Very, very cool, Chris! I am still experimenting with your software on my non-AR4 robot. My biggest stumbling block was the Denavit-Hartenberg convention that differs from my robot to the AR4. Can you recommend a way to adjust the DH convention parameters? At 7:30 in the video, you mention the kinematics. Maybe it can be done on this tab? I tried making these DH changes in the C++ file that runs on the Teensy, but didn't have any luck. (Introduce other errors, like out of range etc) I am super looking forward to taking another look at this latest version. Also, the gcode feature is super important. This could really bridge the gap of CNC & robotics concepts, which are not all that dissimilar. THANKS!! so much for all you do!!! I know what I will be doing this weekend.
Thanks Chris, for your efforts. Hope to take your robot for other level such as increase size a little and increase payload at least 3 kg so can be used for a small industry application such welding
This is mind-blowing!! This is not just incredible, but is a legacy… that’s the best way to describe it. One question: in a modified form, is this accurate enough to replace a desktop CNC router?
Thank you. It may be capable of light milling but it's best for material handling operations. I still have some optimization to do on the gcode aspect as well.
@@anninrobotics Thank you so much for your response. I am looking at fairly light wood carving applications. I shall follow your progress. Best of luck!
Amazing work Chris! I have all the parts for the AR4 MK1 but I never got into building it as I got busy. Real soon i'll have more time on my hands so i'm wondering if you have a list of the different components used in the MK2 so I can get them individually to make the MK2 directly instead with the old Kits
Hello, The aluminum components and and hardware components are the same but the electrical kit changed slightly, it has most of the same parts but there are a few new parts. You will need some 20awg red/black wire, 90° USB keystone jack, Micro to C USB cable, 5.5mm DC socket, rocker switch, and a common 40mm fan. (see the MK2 manual BOM for details) These parts are all easily found on Amazon or If needed you can email me and I can put together an invoice for these parts. The AR4 MK1 motors will all work fine for the MK2, the biggest difference is the drivers. You will need to purchase (3) DM332T drivers and (3) DM320T drivers from Stepperonline as well as a 24vdc power brick. The drives as well as a 24vdc power brick can also be found on Amazon.
Wow, This is great!! I understand that the software can be downloaded and the stepper bought and some parts 3d printed but how would one get hands on all of the specific metal parts that are needed?
Hi Chris. I'm a farmer in Michigan using your robot for some machine vision tasks related to my conifer operation. Thank you for releasing this open-source project. I purchased the Hardware and Electrical kit back at the end of September but have not put things together yet. I see on the website the AR4 hardware and electrical kit are the same for the MK 2 version. Is the stepper motor package the same?

Hi Chris, it is an amazing project that I’ve been following for a number of years. I’m teaching digital Architecture in Brussels Uni, I would love to build one for the digital fabrication lab and using it for 3d printing, do you think it is suitable for this kind of operation. Thanks again for your wonderful project and the philosophy behind. David
This is awesome! I'm about to start a computer science degree and would love to build something like this. Are there any video guides/tutorials on how a total beginner can get started with this?
Hi Chris, I have a question hopefully you can answer. How many degrees of freedom an object can use simultaneously? An object in 3D space has 6DOF how many can it use simultaneously? Let’s say a cylinder is stationary and levitating in the air, it has the potential to move in any of 6DOF. We push a button and the cylinder moves forward- it’s using one DOF out of 6 available. Then we press another button and it starts to roll while it’s moving forward - it’s using 2 out of 6DOF. Then we press another button and it starts to go up while it’s rolling and moving forward- it’s using 3 out of 6DOF. Question: how many DOF an object can use simultaneously?
Hello Chris! I want to make a gantry welding robot (5 axis), according to my dimensions. Tell me, can it be programmed using your program? Sorry if this is a stupid question, I'm not good at this...
The software is written for 6 axis. I havnt tried adapting it to a 5 axis machine but you could likely use the software only jogging in joint mode and always keep joint 4 at zero and I think it would work but I would need to test.
I tried to post this comment yesterday but I think it might have been eaten by spam filters as it included web links: Do you have a list of changed parts anywhere to upgrade from the AR4 to MKII Chris? (I can see the EG series gearboxes are available separately from StepperOnline) My AR4 build is mechanically complete but I've been injured and unable to do the wiring. Finally recovered and was planning to do the electronics in the coming months. The new compact enclosure looks fantastic! It's been so interesting and exciting to follow your progress over the years. Having compared the stepperonline kits I can at least somewhat answer my own question for upgrade parts: J1 Gearbox - EG24-G10 J3 Gearbox - EG24-G50 I can't find the J4 one though, as their Nema11 gearboxes only have ratios listed of 10, 50 and 100:1 Also the new compact power supply - LYD240900- doesn't seem to be listed anywhere, but at 24V 9A with a barrel plug that shouldn't be too hard to find elsewhere You've also mentioned in another comment on this video that upgraded drivers are required, as well as some other electronics kit components: "You will need some 20awg red/black wire, USB keystone jack, Micro to C USB cable, 5.5mm DC socket, rocker switch, and 40mm fan.

@@anninroboticsThanks Chris. The last thing I couldn't figure out is if I was upgrading to the more accurate gearboxes, do you know if StepperOnline have the J4 16:1 available separately? I was able to find the ones for J1 and J3, but looking for J4 they only have 10:1 and 50:1, neither of which feel close enough to 16:1.
Awesome work! Does the Gcode only work in a 2-axis plane or will it work in 3D? I'm glad the physical robot hasn't changed much or I'd have to build another one from scratch!
Thank you. I haven't done alot in 3D as I was mostly messing with 2d drawings but it should work in 2.5D but I didn't do anything yet for handling changes in orientation - just xyz. I have tried to keep the design consistent so no one gets left out. Thanks again.
I look forward to experimenting with this gcode function. When I first got my "some other brand" SOB robot arm, my approach was from a CNC perspective, attempting send it gcode using UGS. It sort of worked for simple 2 axes only. But things got squirrely quickly when all the DH parameters came into play. That is when I started experimenting with Chris's AR4 software@@anninrobotics
Hi Chris, I want to build an AR4 MK2 and would like to start with the most basic parts. In your store, I will need the 'AR4 MK2 Robot Combo Kit', the 'Complete AR4 MK2 Stepper Motor, Driver & Power Supply Package - factory direct from StepperOnline' and the 3D prints you provide. Is that correct?
wow incredible iv been redirected to this vide via one of ur comments im just wondering if u wanna go the cnc/3d printer way where u would make a slicer/cnc gcode generator? I know that is an extremely hard field, but i can see ur product surpassing even industial machines!! Keep it up man :)
So cool, this looks like an engaging build 😮 I've been practicing some languages including the Arduino ide and Python for robotics fun and a career change.
Hey there! Can we get some solid data on its precision for repeating actions like taking some thing from somewhere and putting it to a specific point in space?
Hello, I worked in a foundry years ago and they bought an ABB robot so I asked if I could be involved and then got into programming it. after a few years I got all the robots in the plant. It was fun. I've been all self taught with some help from Google. I barely made it through high school but I love robots :)
Do you sell the linear rail as well? If not - could you link which parts would work? My project requires the robot to be able to traverse around 1.5 meters linearly. Once again, incredible job by a single person.
Thank you very much. I don't have a kit for the rail but the manual does have a bill of materials for it. The software is configurable so that you can make a rail any length you need. If you have any specific questions please shoot me an email at info@anninrobotics.com
Chris you have done an incredible job. This is a life’s work to be proud of.
Thank you!
Its so inspiring that you dedicate so much time to give this for free so others can use, and still adding updates. Thanks so much.
My pleasure, thank you.
Yeah!!! Another AR4 video! Thank you Chris! It's nice to see you refining and simplifying the design so that it's easier to build.
This project is so amazing! It makes me so happy to see a talented engineer like you making such a big impact on students, kids, and even industry. Nice job!

Hello, The aluminum components and and hardware components are the same but the electrical kit changed slightly, it has most of the same parts but there are a few new parts.

The AR4 MK1 motors will all work fine for the MK2, the biggest difference is the drivers. You will need to purchase (3) DM332T drivers and (3) DM320T drivers from Stepperonline as well as a 24vdc power brick. The drives as well as a 24vdc power brick can also be found on Amazon.

Thank you, you can find all the information including robot kits at www.anninribotics.com
There aren't any thermal issues with stacking the drivers together like that?
No I have had no issues, there is air spacing between the drives and the 40mm fan keep air flowing around them.
Hi Chris, sorry for many comments, please inform how will adjust the joints steps in V4 without "Jog Joints in Steps" option same as V2
Congrats man!
woooo! I think your work is very meaningful! Thank you very much!
I appreciate that, thanks.
Thanks so much buddy! I dream of building something that complex :) GOOOD JOB! :)
Thanks!
Really awsome work Chris, would there be any way for me to install more powerful stepper motors to increase payload?
I have seen people modify the design to add a nema 23 stepper motor for joint 3 to increase the payload.
You're awesome bro

Also the new compact power supply - LYD240900- doesn't seem to be listed anywhere, but at 24V 9A with a barrel plug that shouldn't be too hard to find elsewhere

It sort of worked for simple 2 axes only. But things got squirrely quickly when all the DH parameters came into play. That is when I started experimenting with Chris's AR4 software@@anninrobotics
Hi Chris, I want to build an AR4 MK2 and would like to start with the most basic parts. In your store, I will need the 'AR4 MK2 Robot Combo Kit', the 'Complete AR4 MK2 Stepper Motor, Driver & Power Supply Package - factory direct from StepperOnline' and the 3D prints you provide. Is that correct?
Yep that's correct, message me with any questions you have on the project and I'm happy to help.
wow incredible iv been redirected to this vide via one of ur comments im just wondering if u wanna go the cnc/3d printer way where u would make a slicer/cnc gcode generator?
I know that is an extremely hard field, but i can see ur product surpassing even industial machines!!
Keep it up man :)
Just to make sure, the new 4.0 software version be used with the AR4 MK1, correct?
Yes it can. On the kinematics tab just make sure you load the MK1 defaults.
So cool, this looks like an engaging build 😮 I've been practicing some languages including the Arduino ide and Python for robotics fun and a career change.
Hey there! Can we get some solid data on its precision for repeating actions like taking some thing from somewhere and putting it to a specific point in space?
Yes there is a specification section in the manual. Send me a message if you have any questions or trouble finding it. Thank you.
Wow. This is awesome! What did you study/ what work has led you to have the required ammount of information to do something like this?
Hello, I worked in a foundry years ago and they bought an ABB robot so I asked if I could be involved and then got into programming it. after a few years I got all the robots in the plant. It was fun. I've been all self taught with some help from Google. I barely made it through high school but I love robots :)
@@anninroboticsthat's absolutely awesome man. Giving me confidence I can build my own too!
@@anninroboticswhat did you use the robots for in the foundry?
(love robots) Me too. Ever since I was a kid. Now I am 50+ y/o and the robotics world is as fascinating now as it was in the 80s.@@anninrobotics
I had wax assembly robots, investing robots, grinding robots and waterblasting robots.@@legobuildingsrewiew7538
Do you sell the linear rail as well? If not - could you link which parts would work?
My project requires the robot to be able to traverse around 1.5 meters linearly.
Once again, incredible job by a single person.
Thank you very much. I don't have a kit for the rail but the manual does have a bill of materials for it. The software is configurable so that you can make a rail any length you need. If you have any specific questions please shoot me an email at info@anninrobotics.com
Great build! What is the max payload for the bot?
@@end_of_reel_film it's 4lbs or just under 2kg
This is so awesome man. Thank you. New subscriber ✌🏻
appreciate it, thanks!
@@anninrobotics I’m going to build one, one day for sure!
