'Lifelike' Robot that can move, eat and die using Artificial Metabolism
Engineers create ‘lifelike’ material with artificial metabolism
This robot makes use of materials called DASH
(DNA-based Assembly and Synthesis of Hierarchical) that have in-built capabilities of metabolism (giving it that lifelike ‘eating’ ability) in addition with self-assembly and organization – three key traits of life.
This artificial metabolism helps the machine generate new cells, and sweep away the old ones, resulting in a dynamic and autonomous process of growth and decay.
