alt Hacker NewsVery interesting article. I'm looking to get my first robot arm soon-ish, probably something in the SO-101 category. Can someone get reasonably far using recorded sessions compared to training in a simulated environment¹? Do you have any experience with third-party or DIY attachments for robot arms? I assume it's going to be more difficult for something like the Ufactory arm vs. the open models.
I'm only starting down this road but my sense is that ACT and Diffusion Policy both make it pretty feasible to start on real data only. LeRobot also makes it easier to train these. But that's the next step that I'm working on, so I don't know yet.
On attachments: during this project I really wanted a 3D printer several times. So that's probably next on the shopping list.
The Ufactory arm is actually quite extensible: it exposes digital input/output and you have a standard wrist mount where you can mount different end effectors or attachments.
