Oratosquilla Oratoria-Like Amphibious Robot Based on Dielectric Elastomer.

A key challenge for biologically inspired Oratosquilla oratoria amphibious robots is large deformation and flexibility. We have developed a Squilla like soft robot based on dielectric elastic materials (DE). The robot is driven by high-power dielectric elastomer and uses the principle of friction difference and water resistance difference to realize amphibious multi-mode motion. The robot is 9 cm × 5 cm × 7 cm in length, width and height, and weighs 14 g. The fastest speed on land is 12.5 cm/s, and the fastest speed on water is 2.66 cm/s. The robot has high swimming efficiency and can detect the water surface. The experimental results show that the amphibious soft robot for mantis shrimp has high potential and practicability.
