Well guys, it is not that complicated.
I have a very small powerful vacuum cleaner, I just have to design a stand for it and wheels and program it with a microcontroller to go a certain route as a first step.
Then I will add sensors to it and so on.
My first challing is how to handle the 220VAC power cord so that it doesn't get in the way of motion.
I'm thinking of making it on a pully hanging from the ceiling controlled by a dc motor to sensing the tension of the cord.
Does anybody have a better idea?
