I want to improve my programing skills and I thought that to start using physical programing(if that's even a thing) could possible be a great way to do improve it. But I don't know where to start.
I want to be able to build and control a robotic arm. and program it to do specifc task, my ultimate goal is to make it paint something.
Where can I start? Should I build my own robotic arm or it's too hard for a newb and I should buy one insted?
