This is fantastic. I have built 3d Printers from scratch and want to see if I can learn how to build and program this beast! I want to see if the end attachment can be set up to laser cut holes in ø100-200NB pipe.
Thank for the tutorial I have a question. If I just change the DH parameters for the bigger or other types of robot. Is this calculation are suitable? eg. I would like to use the Yaskawa GP12 and I have change the dh parameter of Gp12 robot?
I think there is something wrong with AR4 Denavit table. (Minute:Second = 46:00)
DUDE!!! May ask for your permission to do R&D on these?
For the most part other than selling for profit its an open project thats free to all. What did you have in mind?

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
I have problem , i dont put switches and the software is giving me J1 J2 … with value of 1 why? Thank you
merhaba bundan yapmak istiyorum motor olarak step motor uygunmudur sence ve servo motor kullansam servoyu ardinyo yazilim çalistirirmi tesekkur ederim
Nice robot. it looks like you're using Fanuc style programming. The problem i see is the programmer UI is a absolute mess. everything is displayed all at once making it very confusing and intimidating for beginners. which happens to be your target audience since your aiming for STEM/education. i like how doosan organizes their commands by having you go to a command input tab, insert the command into the program then edit it in properties tab. it only displays what you need to see for that specific command making it simple and more intuitive to use. problem with doosan controllers is switching between programing and JOG or other screen is slow as a frozen turtle. For Fanuc their pendant controller is an absolute mess having 80 buttons you dont know if you can press, but on the screen they still only display what you need to see for editing a command. their menu layout was seemingly developed in the 1800s on a napkin and never updated. But you can jog the robot on any screen just using the buttons and menus load very fast. those are the only two systems i'm familiar enough with to comment on. could be a better one out there but i haven't had the chance to see and use it yet.
This is awesome!
I would like to know how ABB or Fanuc robots are programmed. Could you point me to some tutorial or software?
Hello Mr.Chris Annin. May I know that i can use TB6600 driver instead of your ? Because when i upload AR2 2.0 into my arduino mega then The motor did not move at all. could you please help me with this problem? and one more thing is about power supply 5vdc. Is it optional. I do have only power supply with 5V 3A. Can we use it instead of ur? Thank you

I need to develop some kind of fruit harvesting arm. AR4 seems very suitable for software development. What do you think about whether I can do the necessary AI development on Arduino so that it can distinguish the ripe fruit from the others and harvest it?
hi chris
مرحبا كريس ....انا معجب بمشروعك وانا اعمل مشروع مماثل واريد مساعدتك في بعض المشاكل ..عند تشغيل النضام انا جربت واحد من الاستيبرات علا التويل الذي في الخطط حقك ولم يشتغل
super video !
Cris do you have kits to buy de robot ? It's a big job what you have done my friend
Hi sir, the motor step per revolution you set 400,why is that for a step angle 1.8 steppper motor? Why not 200?
hi mr Chris Annin ,thx for your efforts first,i got a question about steps per motor revolution 400, the step angle of 1.8 degrees, we should have a steps per motor revolution 400,why did I see it on the excel sheet as "400"?where did I get wrong?please tell me ,thx
we should have a steps per motor revolution 200
Voce tem o projeto do robo para fornecer porque seu trabalho e incrível
Thank you very much. You can find all the software and manuals at www.anninrobotics.com/
Recommendation: get some stepper motor dampers or something, that thing is NOISY!
@@flyerminer the video is quite a few years old, those are analog drivers that were extremely noisy. If you check out the latest version of the AR4-MK3 that's almost silent
Hello just in the process of calculating J2 and J3, shouldn't the denominator and nominator inside the theta B calculation be flipped? Altitude/base rather than base(adjacent)/Altitude? Also appreciate your insight on the elbow singularity part, overall great video!
Is it possible to mill all the structural Aluminium parts on a 3 Axis CNC?
@@oithetresen609 I believe my machinist currently makes a couple of the parts on a 5-axis but I believe if you do the setups right you should be able to make them all on a three-axis
As I walk thru the video, I notice another inconsistency, between stick diagram on sheet 3 and DH table on sheet 1, for joint 6, which is just a pure translational offset from Joint 5 (considering joint 0 is the first joint) , both theta and alpha should be 180 degrees, instead of 0, as some of the cosine will be affecting the total result, e.g. -1 instead of 1. Also sign of X6 and Y6 should be flipped, cheers
Also I think direction of Z3 is reverted, on spreadsheet3, as it was constructed by a LH Rule
Hello what software you use to importing all the robots as xml files? is it roboDK thank you!
This is awesome! thank you! I was able to script this in python in half a day while I knew nothing of matrices before I watched this video. One thing I can't get my head around though. When calculating IK, aren't the α and Θ compensation values of J4,J5 and J6 from the DH table used at all?
I was watching the "Made with Layers" Channel where he built an AR4 but at the end he mentions how much wobble the arm had. czcams.com/video/4xD9QCBkxAs/video.html Was there something in his build that he did differently because the results from your version and his look very different. (perhaps a parameter was set wrong or where he set the tool center offset 300mm from the Arm at the 14 minute mark ?) I'm just starting out so I don't know enough to comment so just looking for some insight. Thanks
I did see his video. I sent him this response in the comments: @Thomas, Thank you for building the AR4 and highlighting some of its features. I did want to touch on a few of the comments you made. In the overview section of the manual I do mention pre-applying solder to wires being joined together - I find it easier to pre-apply solder or tinning the ends - and then bring them together with the iron rather than trying to hold the wire ends together and hold the solder and hold iron at the same time, not having 3 hands - it helps to pre apply the solder. None of the wires going to the breakout board call for tinning so I'm not sure about your comments on that? On page 143 I do have some groups of wires soldered together to help group them going to the 3 screw terminals as its a tight fit and difficult to maneuver them into position without them being connected but you could certainly use ferrules in this step if needed. At one point in the past the design did utilize plug connectors and building a wiring harness. Given different applications, motions and articulations all the low cost plugs I sampled proved to fail over time. With this small arm and the limited cable routing and cable arc lengths, direct solder with the solder joints in strategic locations using heat shrink proved to be more reliable, less bulky, less costly and not as time consuming as crimping and inserting numerous plug pins. The primary goal of this project from day one has been to realize a usable robot and at a very particular price point. I've worked with industrial robots my entire career and its always been a frustration that any usable robot was out of reach. There is an absolute threshold on the price as most educators have a budgetary limit so I have made it priority number one to stay under that limit. This drives many of the design aspects, The motors for example are off the shelf variants and cannot be fully customized without adversely affecting the price. There is a limit as to what OMC can customize on these coming from the factory. The machined components are kept to an absolute minimum and as many as possible are cut from flat sheet material. This also drives the bearing designs and tensioning designs as custom machined threads and spindles for locknuts for example is not in the cards at this price point. It also drives some of the belt selections. I did notice the belt tension on your build was far too loose resulting in a good amount of play. Here is a quick video of the forced deflection on my build. czcams.com/users/shortslf_KFFiCdJA - Making the statement that "This robot arm is neither accurate nor precise, rigid or smooth" seems a bit harsh considering. A great deal of effort has gone into this project, I know you have a great deal of experience and a wealth of knowledge in all manner of machines and mechatronics and your design suggestions are certainly well founded but I wanted to explain these aspects of the project, and hope you will convey these points to your audience. Thank you.
Chris, are you familiar with JMC servos? Packaged in stepper form, with a built in driver on the motor. They accept step/direction signals just as a normal stepper would. They are fairly competitive price wise.
Is there a switch or lever to change from gasoline to Natural Gas?
@@classicskatespots1 if there's gasoline in the carburetor it'll run off the carburetor otherwise you just run it out of gas and then switch it over to propane or natural gas.

Great job Chris. you're a great man
Thank you!
Thank you sooooo much. I might finally be able to understand it!
happy to help. Thanks!
Wonderful Work 👍
Thank you!
good
what is the estimate cost on this project, before i start it :)
Total cost is just over $1900 to build the robot, let me know if you have any other questions.
@@anninrobotics i wanna build it, but im in Europe, can i buy the whole kit here?
@@Tjup Yes I ship UPS worldwide.
Here in Brazil I am loving your projects
Thank you!
how much can we save if we 3d print some of the parts, and how much will the rest cost(the parts that can not be 3d printed)? Anyone tried this?
so to build the whole thing how much would it cost for all the parts?
You will need the AR4 motors kit from Stepperonline and the robot combo kit from Annin Robotics. Have a look at the robot kits page which covers everything needed. Total cost to build the AR4 is approx $1900
Theoretically, can I make the arm longer?
Yes you could
Great job! Can the robot be replaced with other motors such as servo motors or brushless motors ?
It would take some mechanical changes but yes as long as they accept pulse and dir inputs
what the actual ...
You're so awesome! Thx Chris.
Amazing work keep doing it ^^
Thank you!
Hey Chris, I was wondering if it’s possible to scale up the robot arm? Maybe to something that was 2 meters long?
