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

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.

I doubt this is strong enough to carry a screen

I have a dobot mg400 but there are quite a few others: uFactory, elephant robotics, annin, dorna, epson (vt6L and their scaras), and lynxmotion is releasing their ses-v2.

Wow, thanks for the list of resources. My problem with most robot arms are either they have small payloads, accuracy isn't very high, are too slow, or software support is terrible. Do you have any specific suggestions for 6DoF? The MG400 looks to have 4.

Mg400 is great for the price no issues. Very smooth! Check out this review video: https://youtu.be/6nGexb_i0aM?si=IP0E76MCGxrTrQEH

What payload are you looking for? Cartesian Gantry’s are your next bet if you want to handle higher loads. Eg. Epson vt6l is ~14k but I’m sure you can build a gantry system to handle higher loads for a bit less!

Dobot software sucks though, I ended up programming it in python. It’s definitely not on the same level as say a Kuka or Yaskawa. Epson seems like the best value out of all the higher end arms. Software looks good, the arms are built well, has a long history in industry, and price is decent

Does anyone have any suggestions on something that's a little higher quality, i.e. more torque and larger, like the size of a UR5 but cheaper than $30k? There's always seems to be a gap between "robot arm with dynamixels/off the shelf servos" and "research-grade arms".

I‘m not sure as far as your technical requirements go, maybe Igus.eu would fit your needs? They do have a fairly good robot automation portfolio that seems to be very price competitive as far as I can tell

Their rebel cobot looks really neat, and price seems great!

It has been here for several millennia... it even has two legs to walk around and two rotating cameras connected to a very powerful LLM...

Nah, that model is expensive and buggy, not to mention closed source.

but it work. I can't believe that we choose from different robots.

I’d use it to pick through and sort the massive pile of Lego my children leave behind after an Easter long weekend. Seems trivial to do identification based on the high quality corpus of block databases. Wouldn’t have to be super quick - you could just leave it running overnight.

I’m sure someone’s written an interesting paper on the ideal sorting algorithm too (i.e. large things > small things vs. ‘just pick up and place the nearest thing’.) I would personally just get it to sort them into basic sets before placing the trays back in their goddamn drawers.
