re: We don't even need AI
Shape recognition:
I don't think shape recognition requires AI.
If a robot moves very fast, it would be interesting to avoid obstacles.
Now, behind the screens on Earth, there are many brains and eyes studying the landscape. If a human were on Mars in stead, he'd also miss some scientific or technical opportinities (he can't be trained for everything); like dropping a sample bag and not noticing it, while those on Earth do (remember Apollo ?).
If the purpose is to move fast, then the robot will miss targets, but that will be the same with humans anyway.
Matter of priorities.
