The Bioinspiration Design Paradigm: A Perspective for Soft Robotics

Abstract

Abstract Biological inspiration is a key design approach for the development of innovative robots. Flapping wings, sensitized robotic skins, insect-inspired compound eyes, and artificial muscles are examples of nature acting as a source of inspiration for the design of novel artificial systems. The heart of successful bioinspired design is the abstraction of the underlying design principles found in biology and their implementation in robotics using state-of-the-art technology. In this article, I introduce the notion of the inspire–abstract–implement (IAI) design flow as a paradigm for biological inspiration in robotics. The article develops the key aspects of the IAI approach and illustrates it on several examples in technology and on a case study of a miniature soft jumping robot. Using a locust-inspired jumping mechanism and a soft exoskeleton allows the robot to jump repetitively with minimal control and only one single actuator. Further, the article discusses how biological inspiration can be a promising perspective for advanced design in the novel field of soft robotics, and it outlines its main design challenges and opportunities.
