Abstract

Evolution has produced a wide variety of organisms that interact with their physical environment through musculoskeletal systems. Movements are often aided by passive characteristics of an organism's body and the inherent flexibility of muscles. Emulating these characteristics in a robot can potentially increase performance and maneuverability, but requires finding effective solutions among an infinite set of possible morphology and controller combinations. Evolutionary computation provides a means to explore this large search space. However, developing simulation models to account for these material properties presents challenges. In this paper, we present an overview of the challenges in implementing such an evolutionary approach. We also present preliminary results demonstrating the effectiveness of our proposed methods.
