Old Old:
Wow. Mars Rover. Older than I thought. So, with the moon, when you say Lava Tubes, does that mean there is lava on the moon? I don't mind having people keep robots together but I would prefer using people as a last resort if at all possible.
Humans + Androids
For example, ideally, I would send people to the moon with robots. I would have the robots do the repairs. The astronauts would give the bots, drones, machines, tasks. I would try to make sure that the robots could repair each other upon command.
Last Resort
But for anything that goes wrong, the humans could come in and fix whatever goes wrong. And I understand that.
Flexibility Like Trees
I just want to try my best, if I were them, to minimize the need to repair. For example, in architecture, some of the stronger skyscrapers which withheld earthquakes were made to be flexible like trees as opposed to rigid. I know robots are a lot more complex than buildings. So, I know my analogy here is not perfect.
Robot Body Guards
Yes. We should have robot body guards to protect ourselves from future robot police, robotic terrorism, etc.
