Correct me if I'm wrong but in the movie the main character due to relativity spends 60+ years away from the rest of the world.

When thay start the journey they take the robots with them.

60 years later that same model and type of robot is able to interface with a new and improved Ranger craft??

Seems to me that the only reason that the spacecraft isn't smaller/sleeker is so that it can accommodate a robot of that particular make and model.

Is this a deliberate hole in the plot by the writers ( so that our hero doesn't go off into the sunset alone ) or is it an oops moment?

EDIT:

What I'm asking is: 1 Is this a deliberate hole in the plot by the writers? 2 How can a robot that is 70+ years interact with a new craft?

for 1 I'm interested in RL answer if any exist (post-movie interviews, script edits etc.). For 2 I would like to in universe if possible.
