An impractical use would be to have a few of them replace monitor arms in a multi monitor setup. You could then rapidly switch between a few configurations. Also, have one to stir pasta in the kitchen.

Pasta is one of the few things you’re not supposed to stir while cooking?

I think you should stir it occasionally. It might depend on the pasta, though.

The geek in me is drooling, but are there any practical home uses others have found for robotic arms? Hacking is always more fun with a good project

Multi monitor robot arm stands would do some cool things. An automated rotating sequence when you boot up would feel like a scifi movie.

Nice. What do you use it for?

Reproducible test scenarios for barcode scanning with a smartphone.

Unless it has to do something with the print quality itself, can't this be achieved using a stationary phone with its camera towards a monitor displaying 3D transformed barcode images ?

That's it, isn't it. The question is not, how far away from that are we , but when can you and I actually afford it? Because, as the other commenter snarkily replies, human maids already exist. The lifestyle of the singularity is already here for the rich. It's trickling down that kind of lifestyle to the rest of us that AI robots will enable. (with some amount of social upheaval.) Lets say the robot that can do that…

I think even more difficult than making it affordable will be making it reliable . OK-Robot says it has has a 1/3 failure rate, and takes ~20x as long as a human, at which point you might as well do the task yourself. I'd want the error rate and speed improved by an order of magnitude before I'd consider it anything other than a fun novelty.

AI technology is advancing at an exponential rate currently. The inquiry remains whether there's a limit to these technologies' potential.

Holding a water pistol to shoot at foxes in my garden might be useful. They other humane deterrents (ultrasonics etc) don't work.

Yes, possibly. But reading from the screen is quite different from reading actual barcode prints, for instance you have to deal with Moirè patterns and such. And frankly it was just a good excuse to buy an arm. Sue me! ;-)

I'm surprised (or perhaps very unaware) that there doesn't seem to exist a company yet that mass produces cheap, high quality, reasonably standardized robot arms. So many things like 3D printers or CNC machines have entered the consumer/amateur level price realm, but this seems to be something still largely unexplored. Seems to have Arduino/Raspberry Pi scale potential, but I haven't heard of a name/ecosystem that popular yet

On the topic of automatically stirring pasta, I saw this the other day!
