Biography
SV7 was the Super-Voc which supervised the other robots aboard a Sandminer. Taren Capel took control of SV7 and he led the robots in killing the crew. Leela released helium into the air so that SV7 did not recognise Capel's voice and so killed him. The Fourth Doctor then deactivated it. (TV: The Robots of Death)
