Grammatical Encodings

Definition

Grammatical encodings are systematic representations used to describe the structure and components of evolving robot morphology through a set of rules or grammar. These encodings allow for the generation of various robotic forms and functionalities by specifying how parts can connect and interact, enabling the evolution of more complex and adaptable robotic systems over generations.
