AR4 robot - External Axis
ฝัง
- เผยแพร่เมื่อ 3 ก.พ. 2023
- Software version 3.0 adds 3 additional external axis to the robots capability. The AR4 is a 6 axis robot arm anyone can build which uses an Arduino based controller and Python interface programming as well as RoboDK. The AR3 & AR4 have been used in hundreds of hobby, educational and STEM programs to teach mechatronics, machining, 3D printing as well as programming. This desktop robot arm has also been used for a wide variety of industrial tasks such as welding, sorting, stacking and machine tending and has also been used in many filming and videography applications.
You can download all the 3D print files, software, manuals and source code for free here: www.anninrobotics.com/downloads

The factory direct motors package is available from Stepperonline here: www.omc-stepperonline.com/ar4... - วิทยาศาสตร์และเทคโนโลยี

Amazing what you have done for robotics past 4 years Chris. And especially the progress in the AR versions
Thanks Chris for that great updates. I sadly still havent had the chance to complete my cnc mill so that I could produce the robot parts in aluminium. But this summer it will surely happen and then I will build one AR4 to play around with. Cause I really love your project!
Chris - anytime you're in southeast Florida I'm buying your drinks!
I appreciate that. I'll have to plan a trip.
@@anninrobotics Same for me if you come over to visit the original Oktoberfest in munich :)
I really hope yourself and everyone else in the mechatronics realize how fundamental you are Chris in the base line of our future! Bravo ! Thank you for all the hard work and for sharing your extensive knowledge. oh, to be even a quarter of your cleverness would make me smile. And remember the answer is 42. Cheers.
Thank you so much, I really appreciate it.
@@anninrobotics Your hard work is fully appreciated Chris!
Thanks!!! I have been trying to write arduino code for my part feeder to feed the robot. This will make interfacing everything much easier!
Thanks Chris!
Muito bom 👏👏👏🇧🇷
Very cool Chris, I admire your work
I have aún AR4 can you make a video Connecting with robodk?
Thank you Chris ! Can axis 8 and 9 be used to drive left and right wheel of a wheelchar to give the robot independent chassis . Will software be completable to do it in real time with bearable latency ?
Congrats for the good work Chris, love it, still building my AR3 :)
i have a question about the 7, 8, 9 axis - can it be defined a s a synchronous rotary axis?
Yes I believe you can calibrate and use 7, 8 and 9 for anything you need.
does it have a timeline & keyframe based editor for programming precise, repeatable movements?
Chris,
Interrupts
Can you send an interrupt to the program when the robot has an error moving? The interrupt should pass details that can be used to try to recover the absolute position.
GUI Organization
It's probably a good idea to group your GUI into API calls. Each GUI group provides all the inputs for the specific call.
The way the GUI is currently, you have hidden knowledge, eg incremental jog applies to each axis.
Love your work!
I would also like a toggle in the GUI to enable/disable hoverable tooltips. I imagine each tooltip would also include a link to the relevant section of the documentation. For examples of what I mean, please see... www.google.com/search?q=hoverable+tooltip+with+a+link+to+the+relevant+section+of+the+documentation&tbm=isch&ved=2ahUKEwjYz8-Knof9AhVDOkQIHVSUAdEQ2-cCegQIABAA&oq=hoverable+tooltip+with+a+link+to+the+relevant+section+of+the+documentation&gs_lcp=CgNpbWcQAzoECCMQJ1C4CljeFWCiGWgAcAB4AIABYYgBogSSAQE3mAEAoAEBqgELZ3dzLXdpei1pbWfAAQE&sclient=img&ei=OkXkY9jKDsP0kPIP1KiGiA0&bih=405&biw=911&client=firefox-b-1-lmBrQGSAQEymAEAoAEBqgELZ3dzLXdpei1pbWfAAQE&sclient=img&ei=t0TkY7-FOIGTkPIP6JOcgAQ&bih=405&biw=911&client=firefox-b-1-lm
Hi, love the video. I wanted to ask what is the best way to control closed loop stepper nema motors with an Arduino. I am making a large scale arm for a project and would love your help
There are a lot of ways it can be done. I'm using the encoder library to monitor the actual steps and compare commanded vs achieved at the end of a move. All the code is free to download at anninrobotics.com
Chris, amazing work. Im from Chile, and im about to purchase the AR4 Robot arm kit . I want to make highspeed videos (slow motion) with my CHRONOS HD 2.1 camera. Do you think this is possible? How fast can this robot can move? Thanks!
Hello, Many people use the robot for cinematography applications. Here is a video illustrating the robot speed. th-cam.com/video/qjtNjkFL3us/w-d-xo.html Please email me if I can help with any other questions.
@@anninrobotics thanks!! Can this robot movements ir positions be teached by hand ?
Hello, the robot can't be physically drag to position due to some of the mechanics and gearboxes. It's more like an industrial robot where you jog the robot and teach positions but you can also use offsets and vision control and things like that
@@anninrobotics thanks!! it is possible to move the robot with a PS2/3/4 control? if so, wll that work also to teach the positions?
@@anninrobotics HI Chris! Do you have or perhaps know a youtube channel of someone using this robot for camera motion control? i would love to talk with someone that has taked the same road im about to start with this, thanks!
Do you have any debounce circuit on limit switches or just do debounce in a software?
It's handled in the software. The switch is wired with the NO contact to ground to eliminate floating voltage issues and then when it's high during the routine it overdrive a few motor steps and then verifies the signal is high.
Hello sir, i have a question regarding the driver. Is it possible to just use the tb6600 driver instead?
Yes no problem you can use any driver
Sir cad files are missing in ar4 version plz check it
Can this arm be used with teleoperation?
The PC control software does need to maintain a USB connection to the robots control board. I'm sure the PC could be operated remotely, probably a few different ways.
Hi Imagine someone build a auto Gripper tool changer !
