It is sort of funny that when shortening it in English, we ended up with “bot,” dropping the “ro,” which looks like the more important part of the word.
Wouldn't be the first time. The English word "bus" is derived from a neologism "omnibus", "for all" (as in, "carriage for all") invented to describe the first attempts at mass transportation using horse carriages. In that word, "omni-" corresponds to "all", and "-bus" is just a suffix indicating dative declension of a plural noun.
