"Sprog" is a term given to a range of small household, commercial and light industrial robot assistants. Differences between the models are usually only due to their Personality Profile, something that was felt made them more relatable to by the humans they came into contact with. While all are programmed to achieve their tasks, differences in personality strongly affect how they go about doing this.
Renold, Rigel and Radcliffe are minor class maintenance robots, tasked with carrying out basic repairs and routine upkeep on a wide variety of systems. As general purpose robots go, they don't get much more general than this model of Sprog.
Single mindedness comes easily to Renold, give him something to do and he won't even respond to orders until he's achieved it to his full satisfaction. Considered rather self-righteous by most, this no-nonsense unit is requisitioned by those sorts of companies that have their work schedules planned out months in advance. Uninterested in the acts of those around him, Renold can often be found optomising filing cupboards without permission or pushing other robots out of the way so the job can be done properly!
Wide eyed and enthusiastic, Rigel is an inquisitive little chap that will explore everything if not given a task to achieve. Often distracted from his work, he is normally ordered by those looking for a friendly robot to work in a family environment. Great with pets and keen to help, Rigel can often be found under the dining table retying your shoelaces or in the garden checking your daisies for oil leaks.
