Sister of Murphy was a competitor from the 2002 series of Techno Games. It was a natural rope climbing robot and it lost its only bound against Twine Traveller. The name was a pun on Sisters of Mercy Ironically Sister of Murphy was hyped by the BBC and by the Techno Games producers as a "magnificent work of engineering" despite its poor performance.
Sister of Murphy was up against Twine Traveller in its challenge. From the start, Sister of Murphy was a clear loser, sluggishly climbing the rope whereas Twine Traveller was almost three quarters of the way. Fortunately for Sister of Murphy, Twine Traveller stopped at the top meaning that Sister of Murphy could now slowly get ahead, only for it to get stuck straight almost immediately. None of the robots succeeded in winning the challenge
- There's a band called Sisters of Murphy that came into being after the Techno Games.
