i have not a direct question about a GPS-Sensor, i have a question which sensor i should use.
I am modifying a vacuum cleaner robot. I already got it drive in directions i want etc.
But now I am thinking about how i get it back to the charging station. How can i tell it where the charging station is in the apartment?
Is the solution maybe a gps-sensor? Or is it to inexact and more for the rough use outside (not for an “centimetre exact” position in the apartment?)
Or is it centrimetre exact?
What could be a solution?
Linux raspberrypi 5.4.51-v7+
I am programming with python.
Thanks a lot!
