Rupert is an English truncation of Latin Rupertus, which derives from Old High German Hruodoperht/Hruodoberht which are also the source of the name Robert. Thus, "Rupert" and "Robert" are different modern forms of the same name. The Old High German form of the name evolved from Germanic Hrothi, "fame, glory, renown, honour, godlike" + Berht, "bright"; thus, Rupert and Robert mean "fame bright".
