Unfortunately, for now, we still have to rely on humans to perform that sort of dangerous reconnaissance work. New technology being developed by MIT, however, kind of splits the difference. It’s a wearable device that creates a digital map in real time, as the person who’s wearing it walks through a building. Link to Original Source

simple heuristics you have to remember...
Yes, don't fall out, and don't hit rocks.
