I found a small snag with my plan:
> I want to explore the raised floor in our office and search for mice.
What if the device breaks down or gets stuck while doing it? It would be unreachable for any conventional means.
And I can imagine quite a lot of reasons for it getting stuck. Especially during the beta test runs...
So it either must have really good (intelligent, self-driving) recovery features or at least a small leash to tow it back.
On the bright side: Others faced this problem too: I.e. Mars and asteroid exploration devices.
