I'll only write some of the points where I see a need for improvement.

the robot needs a name. Its incongruous for the boy to have such an affection for the robot yet still has not given it an affectionate nickname.
the robot needs to learn to speak English other than a few words. Its supposed to be an extremely advanced AI, remember?
the show must give a convincing reason why the robots are so determined to retrieve the engine.
need to introduce some more humorous characters. The smuggler is doing a good job but he needs a female partner in humour.


Keep up the good work!
