The more we come to understand human biological systems, the more biomemesis, the study of imitating nature, is proving to be a powerful inspiration to roboticists. The research has potential as a human prosthetic and in robotics applications in which a machine needs visual input to do a job, such as in space or a dangerous environment. Much robotics research seeks ways to create machines that can go where humans can't go and do things human can't do safely. It seems the way to such discoveries increasingly means studying human biological systems for inspiration and tools for creating robustness and efficiency. The challenges biological systems present offer us new ways to look at organization and communication - as well as the very definitions of human and mechanical.
