Nice! A few things:
At some point, the game forgot how to merge resources.
It was not obvious to me that you had to manually select which resources the robot should collect and that most of them where deselected by default.
I do not think the chain update did anything.
Why build the nuclear power plant when you can build a solar panel? (Though at this point you practically won the game, right?)
It is also quite hard to eject the correct resource from the base.
