Servobot

Servobots were robots created to assist the human residents of Podworld, following the Laws of Robotics. However, when the Tenth Doctor and Heather McCrimmon and the Tenth Doctor visited Podworld, they discovered that thousands of the planet's human residents had been living malnourished lives for 20 years without the assistance of their Servobots. They journeyed to Podworld's mayor, Maya De La Grotzka, and convinced her to help the starving residents of Podworld. (COMIC: Glum Culture)
