New build with flight path

Hey folks. Completely new to this so I’d appreciate any help I can get from you here.Im looking to build a small indoor drone that I can set a flight path on.
Flight path needs to be precise as I will want to go from room to room on a detailed course.
Looking at a budget around 200 to 400 euros.
Once again. Any help Is appreciated.

Another topic. Is it possible to have batteries for drones that can be charged wirelessly(Like in the Samsung phones).
