You can repair the auxiliary generator -twice-

You can first repair it yourself, and then have the robot fix it. You do get the "you have repaired..." notice again, though there doesn't seem to be any ill effects. I do not know if this works the other way around, and if it does, what happens.

A quick and simple fix: deactivate the ability to use the robot if you fix it manually (and visa versa, if applicable)
