All I can say is WOW! Your resume in robotics, I would guess, is fairly impressive. Thank you for posting and teaching. Your channel is very fascinating.
REALLY great work there Chris. My only "problem" (and it is not necessarily a problem for anyone else) is that the stability of such a (lets face it) "light" robot arm is not too good when you have a router spindle as an end effector. I would really like to have a robot arm that can act reliably and accurately as a multiple DOF CNC mill. But even though this robot will not be able to operate as one of those, the work you are doing and the innovations that you are implementing are actually jaw dropping especially as far as the control hardware and software goes. Possibly for your next robot arm you can team up with one of the aluminum foundry folk and machinists that are able to accurately finish-machine the castings and develop castings that will be an order of magnitude stiffer. But in the meantime I will keep watching. Thanks Chris
I've occasionally followed your project. Very impressive stuff. It must've taken quite a lot of time to get this far. Huge props btw for making license so that ie. one man business could build one for him/herself and use it for something. I absolutely understand the "no copying or building and selling robot" policy, but nice you've left this so-to-say poor mans business possibility open 👍👍
@@anninrobotics I have built two of these arm so far for my students. I want to get a third one for my own, is there any plan for a future version MK4? I'm thinking if it is possible to mount the stepper motor driver right on the back of the stepper motor such as the TMC2209 for a quieter operation. It should be able to handle the NEMA23 from the specification. An example would be the PD Stepper by ThingsbyJosh, it may not cost much more than the DM3XX we currently use.
I worked with 2 ton Kuka robots, but i still enjoy watching your videos. This is a very usable robot, many DIY ones are not, hence i do not bother watching them. Thank you. Question, how is the "singularity event" handled? On big ones i would have to reprogram the move that would cause that, to avoid having the option of 2 joints being able to do the same move.
This reminds me of what "toy computers" did to "real computers" in the mid to late 1970s. The company that made the toy computers was named after a fruit. The companies that made the real computers, such as DEC and Wang, are long gone; whereas, Apple is still around.
Hi, can you show us the backlass of your arms ?? Im trying to create a arm but im the process to calculate the best economic option to improve the backlass. Thanks and good channel, im seing you since spain =)
Hey Chris. I just put in a request to join your site/forum. (Devinda) Just putting a comment here in case a RUclips notification reaches you faster. 😁 I'm really excited to post. Sorry to bother u.
@@anninrobotics That does sound like a huge pain. Thanks for building a place for us to commune. I look forward to joining! Also, do you happen to have a Discord community?
@@anninrobotics In R&D, plan to implement a hivemind with local network AI.. This robotics can enhance my knowledge for managing industrial grade robotics with a hive mind..
The closest Kuka would be the KR4 agilus. I think the AR4-MK3 is pretty decent given the goal of making a low cost robot that anyone can build at a cost of just under $2k for a full aluminum version but its not going to be quite as good as a $20K industrial robot. I'll keep working on it though!

Again, great job! My students built two AR3 units. They play chess, They named the AR3 "ChessBot".
Thats awesome, I would love to see video of that. thank you.

buy another one
Hello Chris. Excellent video, very informative!! Thank you for all you do!!
Thanks!
Here in Brazil I am loving your projects
Thank you!

Dude, all your videos are gold. very informative. Thank you for your work and effort.
Thank you.
Great job Chris. you're a great man
Thank you!
Awesome work, and thank you for making this open source. I purchase the kit from your website.
Thank you so much!

Hi Chris, thanks for this amazing project. How heavy can this robot arm lift?
Wonderful Work 👍

Thank you.
Incredible job!
Thank you!
I’m about to retire as a machinist and I plan to build one of these
Un trabajo muy profesional
Thank you!
Thank you...

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

I have problem , i dont put switches and the software is giving me J1 J2 … with value of 1 why? Thank you
Muito bom!
Good 🎉
Will the AR4 exe run with WIN7 ? .............ok got it I see your running a minimum of WIN10

no problem I'll approve the requests tonight. Its unfortunate I have to approve all the users - otherwise spam bots take over the forum.

I don't work out, but my robot does 0:24
LOL
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?

@@SuperKnightwind sounds like a cool project. I look forward to seeing what you come up with.
How does this compare to the equivalent Kuka?
Their isn't an equivalent kuka

@@anninrobotics KR4 agilus costs $60K, I think!
