heh....the black case who's inside is shown in the movie, is a movie prop. It is not actually installed on a functional robot. The original 2004 Stinky used an IFI control system from a FIRST robot, with the robot controller in the black case, and the Operator Interface box on the shore control panel.

The movie versions of Stinky have another enclosure inside the black case, and the black case is flooded. They use small speed controllers and a vEx signal splitter.
In case you didn't know it already, movies contain a lot of fakery. Most folks don't notice most of it. Most folks have no clue what all the parts in the black case in the movie actually do....every thing electronic is just a typical jumble of stuff to them, so when you're making a movie prop, you can just throw a jumble of stuff in there, and 99.99% of folks watching the movie will be satisfied that it really is the functional electronics to make a robot work!
Art is fun
edit: As an example of this, look at WALL-E, study him for a while, and tell me where the actuators are, that make him move.
