Pardon if this topic was fully covered in the past. I have the ultrasonic sensor up and running and just ordered a Digital 3-Axis compass (Seedstudio).
A - My algorithm will first measure the room with the Ultrasonic sensor.
Then knowing what the center is, find its way to it using a combination of the compass and Ultrasound.
B - Once in the center, it could go to a waypoint (on my virtual map of the room) and again return to the home (Center) position.
Obviously, this is a precursor to autonomous maze navigation but I first need to get ‘A’ and ‘B’ fully working.
Any ideas or suggestions? I will share when it is working.
