Robots are automated workers that can work in Factories or can produce Agriculture and Resources. A Planet can support a maximum of 2 robots per Population. Since factories require workers, if there is not enough population to run your factories, robots can be substituted in place for population.
Robots that do not work in factories will produce 1 agriculture and 1 resource per turn.
Robots require no maintenance once they are purchased. Robots can not be used to colonize a planet.
Robots can be transported via freighters to other Planets.
