You mean the geologist rover robots?
Never send a rover to do a man's work.
Seriously, robots can do some things man can't or shouldn't, but improvising isn't one of them. It takes a human behind the machine to do that and if the man isn't clever enough, or the machine isn't capable enough, that isn't going to happen either.
Clementine detected water-ice at the Moon's south pole, because the men operating the orbiter improvised a radar experiment on the fly.
