lets assume this non-flight scenario:
There is a street with supermarkets on the right and left.
I am walking down the street and into each supermarket, then down all the aisles and on to the next supermarket.
Obviously there is no GPS reception inside.
But I have a GPS lock when walking to the next supermarket.
Any chance to map the aisles inside the supermarkets using dead reckoning?
What hardware to use?
Ardu Pilot Mega with Oilpan?
I am a beginner with all things UAV and looking for advice what to look into.
To my knowledge commercial solutions start at 2000+ $US and are out of the question. Tell me when I am wrong.
If it helps I can roll a wheel to measure the exact distance traveled.
