Noob questions warning. I want to make a welding robot arm for our family company and I've been looking for inspiration. I found your video and github page, and it's just pure GOLD. Thanks for all this. I'l be buying the CADs at the very least.
1) Do you think this robot will be enough for welding?
2) I want to teach it its moves by example. I don't know how exactly I'll be doing it, but maybe the simplest method would be making a second identical arm with encoders instead of motors. Or use a SpaceMouse as a force control for teaching. I don't know yet. I'll figure things out in due time, after I first played with the robot as it is. But in general, do you think it's feasible? (I have no idea about any of this yet, but I'm generally quite good with computers, technology, and figuring things out)
3) Aren't servos better than stepper motors (something about losing steps and knowing current position)? If I wanted to use servos, would it be possible without major changes?
