can such a robot feed wire from a roll eg for soldering?
I really think about robotics, creating a position for soldering tiles in tools

Thank you for the answer, and do you think you would like to design such a wire feeder for example for soldering as in the movie 1.09 minute?
You should start with a 3d printer extruder for feeding the soldering wire. It's just another stepper on the arm. Add an arduino mini and a small stepper driver on the payload and make it extruder while a digital pin coming from the arm controller is on, plenty of how-to on youtbe, instructable, etc.
If you are asking if the robot could hold a soldering gun that is fed with a wire feeder. Absolutely. The only concern that i can think of is if the solder guns weight is less than the robots payload. And I'm pretty sure you are good for 99% of soldering irons.
