9A....so lets see here....the Robo-Chopper does it thing all day long over a very hot radioactive area...gets lit up doing so...then who is supposed to service the thing....a Robo-Engineer?
Come to think about it....there's the deal...no spanner twisters to deal with! Just type a few commands into the computer....shove a work card through a card reader....and zingo....work done...no tea breaks...no fag breaks...no surly attitudes....and if one decides to lay out on you...you just hit the kill switch and that it sorted.
