My personal experience with two different robotic arms (< $500) and some additional research is the lack of high level software and libraries, which is quite crippling as it’s very complex to control.
If you’re not used to control theory and inverse dynamics it’s quite tricky to control it (especially at 0.25mm) and you’ll never get to actually use it to perform what you want.
You might have better luck with low-end industrial robots but the cheapest are $2500 and more.
(I’m similarly in the market if a product can prove me wrong, especially interested in something with some computer vision integration)
- lokl 5y agoThank you, this seems like a very important point. Which arms did you use (if you're comfortable sharing)?
- omneity 5y agoJust random brands. I think it was something like Yehboom and Sunfounder or something.
- ianai 5y agoSo I’m very far out of my depth here. But it seems like we humans learn how to use our limbs through something like trial and error. Ie in other areas, babies vocalize a lot of odd sounds that vaguely, eventually sound like words. It “looks like” what random variation on inputs and weighting based on outputs might “look like” third person. Is that way far off the realm of possible with motors/etc?
- omneity 5y agoIt’s a very interesting thought. I personally am not a robotics expert, but it seems to me there are two obstacles: loading the arm with enough sensors and encoders to detect outside feedback reliably, and the speed of learning iteration (limited in the real world by physical laws etc).
