Key Points

  • The paper studies embodied-AI hexacopter drones that jointly evolve their physical morphology and learn controllers, leveraging the synergy between evolution and learning.
  • It reports that the approach can produce “non-conventional” drone designs that outperform traditional fixed-structure hexacopters on more complex aerial tasks than prior work typically evaluated.
  • Beyond robotics results, the authors contribute new evaluation metrics and analyses to better understand how morphological evolution interacts with learning and reveal previously unidentified effects.
  • The methodology and analysis tools are presented as domain-agnostic, aiming to support general foundations for embodied AI systems that combine evolutionary search with learning-based control.

Abstract

Evolution and learning have historically been interrelated topics, and their interplay is attracting increased interest lately. The emerging new factor in this trend is morphological evolution, the evolution of physical forms within embodied AI systems such as robots. In this study, we investigate a system of hexacopter-type drones with evolvable morphologies and learnable controllers and make contributions to two fields. For aerial robotics, we demonstrate that the combination of evolution and learning can deliver non-conventional drones that significantly outperform the traditional hexacopter on several tasks that are more complex than previously considered in the literature. For the field of Evolutionary Computing, we introduce novel metrics and perform new analyses into the interaction of morphological evolution and learning, uncovering hitherto unidentified effects. Our analysis tools are domain-agnostic, making a methodological contribution towards building solid foundations for embodied AI systems that integrate evolution and learning.
