Extra-Terrestrial Navigation with Particle Swarm Optimization (ET SwarmCats) The ET SwarmCats were awarded funds for the design and construction of laboratory robots. They will design robots to harness particle swarm optimization, based on the animal habit of utilizing the advantages of traveling in swarms. The goal is to devise small robots that work in unison to achieve a common goal, yet think and act individually when necessary. Eventually, they could be used for searching operations on extraterrestrial planets and asteroids. The project is multidisciplinary.
