This paper introduces an entire development trend of the bio-inspired robots, details of the single locomotive robots, and multimodal robots. Unlike general robots that utilize rigid structures and complex control techniques, creatures have compliant and soft body structures and survive in a simpler way. Inspired by the creatures’ standout performances, bioinspired robotic research has been started by implementing the single locomotion modes of insects such as crawling, jumping, and climbing. Recently, to expand locomotion domain, multimodal robots are actively being studied by integrating more than two locomotion modes of the insects such as jumping-crawling, jumping-gliding, and flying-climbing. Based on the reviews, we carefully suggest how the bio-inspired robotic research will proceed.
