In the games
In the first game, Junkbot is simply searching through the factory he works in for the trash he loves to eat, while avoiding enemys and hazards.
In Junkbot Undercover, Junkbot is still attempting to find tasty trash to eat, but at the same time, he is investigating the mysterious "Project X".
In the games, Junkbot will simply move straight forward, until he either encounters an obstacle he cannot climb over (in which case he turns around), or encounters an enemy (any robot other than Junkbot himself), or a hazard (such as a laser, a dripping pipe, a fire block, etc). If he runs into an enemy, he will die (unless he is protected by an "S" (shield) block). The same goes for hazards.
