Oct 2025: New paper at IROS 2025! "BlueKoi: Combining a Tuna-inspired Tail with Koi-inspired Body Bending for Maneuverability”. Led by Irene Sha, this paper presents the design, experimental characterization, and low-order model of a new untethered fish-inspired robot for future coral reef exploration. Check out the awesome Video on our SSR channel, including new experiments at the Jersey Shore! Inspired by the koi’s bilateral body flexibility and the tuna’s high-performance but stiff caudal fin, the BlueKoi achieves 2D maneuvers by integrating a turning “head” that acts as a yaw control surface, combined with an efficient Tunabot Flex tail for strong locomotion. Fish-inspired robots have the potential to monitor complex and fragile natural environments like coral reefs, while being less invasive than noisy and unsafe propeller-based designs or permanently deployed sensors.
