The robots are all original, created specifically for the project, representing 14 species classified by distinct behavior strategies and body morphologies. Obstacle avoidance, movement or sunlight detection and interaction with the public are some of the robots skills.

Robotarium X, the first zoo for artificial life, approaches robots very much in the way as we are used to look at natural life. We, humans, enjoy watching and studying other life forms behavior and, sadly, also to capture them. However, in this case, although the robots are confined to a cage it can be said that, not like animals, they enjoy it. In fact the Robotarium is their ideal environment with plenty of sun, smoothness, tranquility and attention. There are no fights or aggression and the only competition is to assure a place under the sunlight.
