ERAIASON - Evolve robotic animats in a simulation of nature
A downloadable evolutionary sandbox for Windows, macOS, Linux, and Android
[EARLY ACCESS]
Project ERAIASON – Evolving Robotic Animats in a Simulation of Nature
EVOLVE YOUR OWN AI ROBOT!
You are The (zoo)Keeper overseeing a population of evolving AI robots in a dynamic voxel landscape. These robotic animats walk, jump, eat, mate, fight, and adapt to their surroundings as they strive to survive and reproduce. In theory, the capacity for their intelligence is limitless, as their brains can evolve to any shape and complexity. Will you choose to passively observe their evolution, letting nature take its course? Or will you intervene, shaping their world and influencing their evolutionary path?
Design your own animal robots, build custom terrains, manipulate the environment, interact with the animals, and watch as each generation learns, adapts, and competes in a simulated ecosystem that’s as unpredictable as nature itself. The fate of their evolution is in your hands.
---------
Introducing a new god game and evolutionary simulation, where you evolve the brains of artificial animals to make them more intelligent, to better achieve survival and reproduction. The animals are AI robots controlled by classic neural networks and other types of AI such as non-axiomatic reasoning system. They have a simple form of vision sense, touch sensation, and internal sensations, and they can move each individual body segment. They can eat, mate, and fight, all while learning and evolving in a sandbox voxel environment.
You can create custom robots in the Animat Creator and import them into your simulation.

Note: this project is free and open-source, though the version here includes a compiled .exe, is more advanced, includes GUI and additional features.
