I’m not sure what the “fill out form if you are interested in building” link is all about on github, but at a glace, this looks like a solid project to build IMO.
Yeah it’s neat but I never know what to do with this stuff if you made it. Like, I’m not going to go full on “stuff made here”. Hard to see the practical value.
Jiggling your mouse to keep your status from going to Idle
Nah but ever since I learned how to program industrial robots at my job, I’ve dreamt of a 100% automated coffee making system that has a scientifically perfect cup of coffee waiting for me when I come down the stairs in the morning
I have not built such a device. The programming skill is a big first step to understanding the potential applications. Assuming the accuracy shown is replicable, the example joinery and mechanics is invaluable. I have tried making low lash joints with 3d printed parts. This was not an easy problem for me to solve from scratch. From my experience mostly making functional prints and mechanisms, a project with the results claimed here looks like an enormous project with a ton of engineering. It is the kind of thing where I would pick up a lot of design ideas and principles.
Lastly, assuming the final product is durable enough, it changes the time/value balance for repeatable tasks; so anything can become cheap. The first thing that I think of is sawing. With a basic hacksaw blade you can cut through almost anything just by repetitive motion. It becomes possible to cut through almost anything that would be impractical normally due to effort and time. This kind of machine really benefits from getting paired with other machines. It could even be used with a 3d printer to replace build plates or remove prints.
Amazing, thx for sharing.
Manipulating with objects or serving 3D printer sounds like perfect task for robotoc arm, but cutting or machining not really. Its heavy work and it would be more suitable for cartesian XYZ machine. I have no real experience with robots in production, but Ive seen super expensive robots serving other machines and failing quite often.
That arm could wipe nozzle just before print starts, open/close cabinet door when needed, move camera in space for some crazy timelapse, maybe 3D scan model on build plate, photo session shooting of every model you printed or if you really get mad it could also switch extruders for multi material setup. It would be awesome to have that at home, shame I dont have knowledge, time and money to accomplish that 🥺 maybe in the future
Oooo this looks cool as hell! I’ve always wanted to design my own robotic arm but the electronics part always intimidated me.
The link that OP mentioned looks like they are trying to sell you various components. Also the gripper is a separate item altogether. While it says it is Open, if yiu have to buy that PCB, it seems less interesting. I figured it would be running off a raspberry Pi or something like that.
It isn’t a bait scam or anything. The full Gerbers and schematics are present. It uses a STM32F446 and TMC2209’s. This is really standard stuff. No raspberry pi or anything like that is capable of running steppers. This is like standard printer hardware. Offering the completed boards just saves the user a ton of time and money compared to ordering your own or etching something.

I didn’t think it was a scam, but I figured it was a way for them to make some money while still stating it is Open.
How many others are considering building one?
No one is making money off of small run hardware like this. The time invested in such a project will never be recuperated. This is a passion and/or university graduate project. The boards available are likely just extras from a small run they did with a prototyping service and were close to a minimum order quantity. If you order the same type of thing from somewhere like PCBway, you’ll be stuck with extras too.
I’m too busy learning AI for a project like this ATM, but I would like to build this at some point in the future.
What would be your use for it? I agree it’s super cool, I just struggle to think of how to use it if I’m not manufacturing something.
That’s always the thing, right?!
In my younger days,I was so quick to say “cool,I want one” and before I even came up with a need for it, i’d zlready have one on order. Bought so much useless junk that way. I stopped doing that years back.
I think in this case, I might make an exception. I design stuff for a living, but it’s all (or mostly) mechanical. Just to mess around more with the electronics side of things, I might build one eventually.
If only for holding the antenna during a satellite pass.
I wish I could get a hold of an antenna rotator either fully assembled, or at least a complete kit, without significant number of parts missing.
I don’t want to tinker with stepper motors and automation integration while tinkering with radios. Damn missing dependencies all the way down!
Seems like a great project for a robotics club at a school or something, thanks!
I love projects like this if only for the learning opportunity.
The process of building this, especially for someone thinking about entering a robotics/automation career, would be priceless. I’m sure this is an industry that will continue to see a ton of growth in the next few decades.
I’m not saying this kind of project will future proof your career or anything, but people who do projects like this for fun have future proof skills.
Someone is totally going to turn this into a reprap 3D printer, and I’m absolutely here for it. I can’t wait to toss on a 1mm nozzle and start printing some massive 3D printed bog planters for my savage garden hahaha.
