I don't think Curiosity and its cousins can tighten down leaky bolts on pipe connections, which is what I think of when the term "maintenance" comes up. The closest we have right now in that vicinity is Spot from Boston Dynamics, and it basically only acts as a universal monitoring tool to go yell at a human to fix things. I guess what I'm saying is that robots can identify problem points, but at the current time can't actually troubleshoot or resolve those problems. Those are really difficult problems to solve.
