Manta ray-inspired robot sets new speed record in swimming technology

Researchers have developed a new soft robot inspired by manta rays, achieving a swimming speed of 6.8 body lengths per second, surpassing their previous record of 3.74. The new design allows for movement throughout the water column, unlike the earlier model. The robot features fins that mimic manta rays and uses a flexible silicone body with an air chamber. This design enables efficient movement by inflating and deflating the chamber, allowing the fins to bend and return to their original position. The team has successfully demonstrated the robot's ability to navigate obstacles and carry a payload on the water's surface. They are now focusing on improving lateral movement and exploring additional actuation methods.
