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.
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.
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.

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?
