This is a true labor of love. I've worked on a similar project for about a year, though I'm focused much more on the software side. I'd love to combine my software with your design when the software is ready. It's designed mostly for robots that are focused more on speed and strength than precision, but it is very adaptable to the machine. What I mean is, your robot is great - and it also inspires and informs other robots that have different goals. I'll send you more information as soon as it's ready. I think you'll like the result.

I work in a robotics lab and have seen a lot, but this blows me away! Great job!

This is amazing! Souch a great project! Been waiting for the kits. I am buying this to myself as a Christmas present now!

Chris, always great to see a notification from you. It's fantastic that you have documented all the progress you have made over the past couple of years. More power to you!

Thanks for sharing. Already downloaded your code and docs from Github. Thank you for an incredible amount of knowledge and work. I especially liked the parts list you put in the PDF, wow, nicely documented!!!

You’re an amazing practical human being and your robotic projects inspire me very much. Thanks man

Thanks for your time Chris, awesome work!

Just two words, awesome work and so grateful for the open source as so helpful for educational purposes, bravo!

Thank you for an amazing project. We appreciate your great work

This is such a professional and informative video. I appreciate your effort and thank you very much. Keep it up!

Awesome !! Thank you so much for sharing this wonderfull piece of ingenuity/technology/craftmanship !

Glad to see this project mature! I started looking about how to teach myself more in-depth robotics freshman year of college, after a year and some experience I'm gonna start working on this project as a 2nd Year, it's nice to have a sort of guided learning experience because it's hard to know where to start when you barley know anything haha. Thank you for this!

Hey Chris, After working on my first big robot I now have even more respect for your work. Furthermore, looking at your code, its beautifully set out for others to read and understand. Thank you for sharing your work.

Wow, wonderful work! Thank you for making it open source 👍

Beautiful. Thank you for your work :)

Great work Chris. it keeps getting better . I will let you know once I've built one

This looks amazing. Great work!

Amazing work. Please keep doing what you're doing. Truly Awesome

Dude, I'm so happy you uploaded this. I emailed you a looong time ago outta the blue just to say your shit was amazing, I was so impressed then, and I'm even more impressed now.

I really think your robot is the best in the world for the price, the air 2 is a game changer really appreciate the effort that you have made

This is awesome... I'm really going to have to take a detailed look at this. It would be incredible of I could get this to work with my PUMA 560 series robot arm... and replace the failing 40-ish year old controller. Although... this robot would certainly be much easier to haul around for demonstrations and such. Thanks for a great job!

Awesome work! Thank you for sharing it!

Very gorgeous design and a great project.

You are a very good master engineer teacher and a great man .... Thank you so much for everything....

I can't wait to build mine. It's nice you have these awesome kit's ready to be put together. My last arm took almost a year to source all of the parts. Bearings especially.

such a great work. Mine finally work, I just have to found a clamp.

You are my personal hero of robotics !!!

Fantastic work!

Super super super This Projekt...100% Best...Bravo my Friend...Thank you.

Wow thank you allot , this is the best one that i could find

You're awesome and this is very inspirational, thank you!

This is great , i will use it for shure in my first production line .

Thank you for making it opensource

huge improvements!

I am the Math, Science and STEM coordinator for a school district. We will base a course based purely off of your build and open source resources. Thank You!!!!

awesome work, thank you for your video.

This is awesome!

This is sweet! Thank you.

Great job, easily the best DIY robot I have seen.

Excellent work, thank you very much for sharing. Questions: the robot sort of vibrates occasionally. What is the reason and how can this be overcome? Do you have values for the accuracy and the repeatability at this stage of development?

Amazing work. Thanks a lot

Thank you. This is amazing. Top video!

Thank you SO MUCH

Very cool robot very nice video thank you very much for sharing looking forward to your next videos

Damn, had a look at the kits... I want one lol. Does it have a teach function where you guide the arm by hand and then it records and repeats? I see the SW files are available, are these the proper files with all the features still editable or have they been reduced to dumb bodies like the step files? What year and SP of SW are you using? I would love to develop this for doing some machining work or even better a diy Moley Robotic Kitchen for those Sunday morning still hung over fry ups lol.. I used to design robotic arms and tooling for subsea ROVs in Aberdeen, Scotland for the oil & gas industry. Have you heard of the TITAN 3 and 4 ROV arm and manipulators. Great pieces of kit. Always wanted to have go at an arm 6 or 7 axis based CNC machine with tool change and material feed system.

Very nice Robot 6 axis!

thanks so much for youe amazing hard and brilliant work

Good job bro.😊 thanks for vid.

Great job man! This is pretty remarkable. Are you using any feedback encoders on your steppers?

Amazing work... i have a question.... will same codes and application work if i place the motors without belts, but for same axis?

thank u very much, it was inspired.

Thank you so much.

@Chris Annin Watching this project develop over the last year and change has been awesome. I've been interested in the analytical side of things for a while, and your kinematics series was very helpful in understanding that. Do you have any plans to create a similar series for the path planning analysis of a 6 axis robotic arm (Jacobian, joint space to Cartesian space, velocities and accelerations, etc.)? Do you have a list of resources you used to develop this part of your software/theoretical model?

lookign foward to see footage with gopro mounting in this arm robot.. especialy with slider. i think it would be awesome

Nice intiative sir. All the best

Can servos be used? Did you did Linux CNC for the controller? Can I buy the controller fully built from you?

Can you change the grip for a drill setup? Oh by the way great work!

Hi Chris ! Im printing the ar2 right now , but im wondering if theres a possibiliti to run 2 or more ar2 robots together so the can work together ? Thank you

Chris , is it possible to mount a spindle on the arm to make it a cnc machine? Planning to make a 1.5kW cnc machine and I think this might do the job. Great work sir! Thanks in advance

Good luck, man.

awesome, great jobs

cool work

very good and functional, with this version that has circular interpolation, the sketch arduino _sketch is working now, thank you very much.

What a cool project! I was wondering; What is the lifting capacity when the parts are 3D printed? What is the weakest link in the chain? (Steppers, mechanical parts, belts,.. ? ) Also, do you have an approximation to the total cost of all the components?

That's an incredible piece of kit. What's the holding force like? Have you tried to use this as a machine tool with a router head? This would be great with a auto quick change head.

God bless you .

Hi, good job. BTW what is speed, load, range?

Great presentation Chris, in terms of the architecture for your next iteration, have you looked into the Mesa FPGA cards that are used a lot with linuxCNC? Thinking that maybe a lot of the groundwork would be there in terms of source code and interfacing with closed loop servos.

Wow so nice

awesome work /\

awsome bro thank you

hi just found your project from watching dHewlett video very cool, have you any ideas how to get a robot arm to pick up food like cookies and move it?

could the program control a lego mindstorm? because i have build a 6 axis robot with lego technic

your robots are crazy, one question it will change a lot if i put here rasberry pi 2B?

"Thank you for watching"?? No. Thank YOU for making the video!

Awesome!

oh this looks way more stable than the plastic version.

Bravo !

Very amazing work, really appreciate your hard work here. i do have one question though, can this be done without a relay ? why is it necessary? another question, can solid state relay be used in place of this relay ?

Price for a completed aluminum bot? Beautiful peace of kit!

Love this project, Chris, you've done a great job. Can you give me a hand in identifying the actuator (grabber / hand) @ 1:17 that picks up the thin piece of metal? I am trying to google it but no idea what to call it.

any plan to replace the steppers with servos? would make it a lot cooler imo

If I wanted the arm to be able to lift not 4 pounds but 400, and I didn’t want to go with massive gear boxes that would really reduce the speed, could simply getting much larger motors do the trick? I guess I could also thicken the robotic arms so that it could hold motors that are 100 times heavier.

Amazing work. Can you scale this down so that as many people can afford to have one? This should also be inexpensive and one of your goal but cheaper than cheaper would be much more accessible.

Love.

How can I buy something like this

This is a job well done. Would be possible to use this robot like a 3d printer? I mean to install a hotend at its hand and use It like a printer.

Hi Chris, The robot is awesome. Could you confirm the total reach? You mention at 1:53 both 23cms and 25inches.

for speed movement, is it possible to modify..? like speed ramp camera movement, i interesting for high speed camera movement recording..please kindly reply....thank's

This is great, I was thinking of getting the iGus robot (9000US$). But now I can build my own.. Thanks so very much for sharing your information to the rest of the world!

Any concerns with stability, durability or accuracy if the entire build is PLA 3D printed?

SUPER THANKS...

This is amazing. I think this work great for a personal project of mine, but I need to know a couple things. How loud is it? How smoothly does it move at low speeds? If it had a spoon with an egg on it, would the egg stay on? That's how smooth I need it to move.

The best sr. :)

Excellent work realy awsome can conect robot with robodk??

Could this be compatible with gcode for CNC?

How hard do you thing it would be to build a cnc robotic arm?

Good job , i will modify robot arm 6 axis retrofit , i will show you later

Hi, I'm still following, and it's awesome. Do you think it can handle a milling attachment? not for metal, actually for milling shapes on wood. eg sculptures.

С меня лайк, это КРУТО🔥 💪
