According to one source, Robby was the nickname given to a mobile robot which Emil Lang attempted to use to go in ahead of the human personal. The robot stopped responding outside the hatch on the side of the ship, but ran inside after the others had went on without him. He was later found completely rewired with advanced alien technology.
