There was an old sci-fi story with a robomule.
We need a kind of Boston-like robohorse in case of a time portal gets unexpectedly opened during the ITER and LHA experiments, like in Stargate, but into the medieval or ancientry.
Also, there is another problem: what should be the time traveller's weapon, as the assault rifles are an obvious overkill.
(Except the red crowbar which is present by default.)
(Every self-respecting scientist always keeps it at hands, after the case happened to Gordon Freeman.)
