This is awesome! As a quadriplegic I struggle with workholding and part swapping in my mill and lathe, I have been eyeing the AR2 for awhile in your videos and the AR3 interests me even more. This video just convinced me I need to get building one! Thanks for putting this out in the world for others to benefit from.
Im in the same situation, got injured in car accident late 90's (quadraplegic, broke my neck 6th vertabrae), im full of ideas but frustrated since I cant do everything I would like. Fingers are not functioning at all but my arms ok'ish. Really torture to watch all these nice videos. I might be able to do some of the build with a lot of time and nerves.
Chris, that is best automation invention that I've seen in a very long time. Congratulations on getting it all up and running. Totally gobsmacked. Sincerely Aaron (Melb, Aust).
Though, a really cool set up, it really shows the skill of the man who put the whole set up procedure together, pnuematic clamps, clamps, code and the AR2/AR3. With the robot, itself, with just having a simple menial job.
You should team up with youtuber Skyentific to implement a differential gear setup for joints 5 & 6. He’s good with these, and your robot would be totally next level with this feature. 👍🏼👍🏼👍🏼
with all the failure and successes in your journey with this project, the final sesned result is success. i was very excitied when you started this project and i'm very happy with the total outcome, be it learning, business experience, making cool machines..etc
This video just popped upon the home page, I'm glad I watched it except now I can't find my Jaw... it dropped when I saw all the homemade robotics and WOW you got a Sub!
Pretty cool. The only thing I don't get is after all the work to automate this job, which is awesome BTW, that zip tie holding the air line by the mill head wasn't snipped. You must have done that on purpose to drive people like me nuts.
hi sir very happy to see work I am a young Cameroonian who likes robotics please I would like to have all the details of the video to realize the robotic arm
Sir,How do you integrated this robotic arm with CNC means after holding the workpiece by robotic arm the CNC open the chuck .what communication Used there to integrated both.please help me in details. Thanking you sir
Chris, this is an exemplary example of how the robot can be used. Well done. I would like to mount it next to my mill and have it do the tool changes for me. Like an arm reaching around and putting them into the spindle. what are your thoughts on this. Does that sound feasible or just stupid.
How has this littlest stood up over time in this application? I have some lightweight CNC tending applications in mind for a ar4. Not to mention a few other things like a small scale anodizing line that I run in 5 gallon pails. Having a robot tend it would melt bettered results/repeatability. I’m not always on time swapping to the next bucket process
As far as I know the robot and process has been fine. This particular tending process was setup by Werner Berry who also has a channel here on RU-vid. I believe he was also building an aluminum AR4 robot as well.
Man this is so amazing. I am trying to learn inverse kinematics specifically for robotic arms and I am finding it really hard to get my head around it. Its really impressive that you've made an entire robot plus its control box and software on your own. Any tips for beginners like me on where to get started?
as far as the kinematics I made a series of videos that explains it, I want to remake the vids with more detail soon but here is the first one - I hope this helps ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-FIx6olybAeQ.html
This is really cool! I watched through your videos about forward and inverse kinematics, are you using jacobians for the linear end-effector motion or just using very small steps while using inverse kinematics?
This is an interesting and at the same time difficult job - to precisely synchronize all processes. It looks like art! But the question is not about that. Chris, I ran into a little problem and don’t know where to go next. I don’t understand how linear movement occurs along an arbitrary vector. Is it a point cloud or a real-time parametric equation for all axes at the same time?
are you asking about the robot kinematics as far as the robot running a linear path? shoot me an email info@anninrobotics.com sometimes I miss questions on the youtube comments stream.
You're doing allv that nice work on the electronics and wiring, and then you 3d print the arm structural parts? You already have the mill. Aluminum is cheap!
🤪Can you recommend a book(s) to supplement the building of robotic systems? I know maths and programming, weak in electronics and system design. Btw, those geared motors from stepper online are sold in a 5pack so I am making planetary gear boxes to go on the stepper motors, and a third of the way through the process of making 50:1. Though I have no clue how to source the encoders yet the stepper motor drivers do come with closed loop. Anyway, take care and look forward to making AR3.1 :)
I'm wondering how you are able to turn a profit with a system like this? It seems like it's fairly complecated and time consuming to make it worth the effort for a few hundred parts. Don't get me wrong it's mesmerizing to watch but just curious.
It probably makes sense if he has a lot of jobs on a similar scale (reprogramming the same setup for different jobs would be reasonable simple) It could also make sense if he has multiple machines, but only himself to operate them. He can make 2 operators worth of parts, with only one operator.
Hi Chris, thank you so much for making this. I'm very excited about this robot arm and is ordering stuff to build one myself. I have one question though, the stepper motor kits ordering from stepperonline cost $110 for shipping. do you know why it is so expensive? Thanks.
@@anninrobotics Thanks, I will try to build this robot arm. Hopefully if I can get it working, I will try to contribute in writing a mobile application that can be used to operate it.
Hello, just getting back to working on some ideas for my next software development. I moved 6 months ago so ive been pretty busy getting things setup and of course working my day job. Should be some new stuff in the next few months.
The motors package is $480 and the hardware is $370 - misc and electronics are approx $350 - you can find all the info at www.anninrobotics.com on the robot kits page. thanks - Chris
@@anninrobotics that is an amazing work mate.. I have downloaded the manual.. It was detailed.. an amazing amount of work.. I thought to build it for my final study project.. and try to simulate a flexible palletising system.. to cut the cost I might 3D print it or simplify it to a SCARA robot.. Whatever I do, I wanted to thank for this amazing amount of work.
Hi! I love this and I aim to buy one and build, however when I go to download the free open source files, it seems to not be free at all. Where can I download them for free to test different use cases and implementations?
All the software, arduino sketches, 3d print files and manuals are free on the website on the downloads page. Let me know if you have issues downloading. The CAD models for the arm itself are $99 on the robot kits page
@@olorf yes it's free for education, hobby and personal use, I just ask that people not resell the project for profit and I make a little off the cad models to fund development and pay for solidworks licenses. This video was actually sent to me by the gentleman that built it to feed his CNC machine, it shouldn't say totally open source but it was a really cool video that I wanted to share so I apologize for the confusion.
@@anninrobotics it isn't weird or unfair that you want money for your amazing work. And I will definitely let some of my money go your way. To claim it's open source and free isn't correct if you're charging for the source, of course. Perhaps consider sharing an STL of the assembly, or a simplified STEP dummy with a single body. It really helps to measure if the robot will fit within an existing project :)
The robot software is very similar to an industrial robot program where you can jog the robot and teach points as well as offsets period you can download the software at the website in the description
