Manta Ray-Inspired Robot Sets New Speed Record for Soft-Bodied Swimmers

The soft robot, developed by researchers at NC State and UVA, achieves 6.8 body lengths per second using a simplified energy-efficient design.

The robot's design mimics the efficient, wing-like flapping motion of manta rays, enabling both speed and maneuverability in water.
It broke the previous record for soft-bodied swimming robots, reaching a speed of 6.8 body lengths per second, nearly double its earlier performance.
The innovative monostable snapping mechanism allows the robot's fins to passively return to their starting position, reducing energy use and mechanical complexity.
Researchers demonstrated the robot's ability to navigate underwater obstacle courses and carry payloads, showcasing its versatility for potential applications.
Future improvements aim to enhance lateral movement and explore broader uses, including deep-sea exploration, marine life surveys, and environmental monitoring.
