These are correctly named prototypes, but they're not production prototypes, the type ervin007 apparently is thinking of; they're R&D/engineering prototypes, to test different designs and paths to achieving the same goals. CSA joint tests them with NASA, just like they did the Canadarms, and NASA has the means to put these on the moon, on Mars or in space.
