We steal one of the robots, program it to be on our side, send him back in time to kill the person who invented robots and protect the person who figured out how to program a robot to go back in time.
Monkey wrench time! The robots have to invent the time machine, because we will be to busy sipping on our "Big and Large" drinks!
