Abstract
By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Data detailed on Robotics have been pr esented. According to news reporting originating in Xi'an, People's Republic of China, by NewsRx journalists, research stated, "Bionic manta underwater vehicles will play an essential role in future oceans and can perform tasks, such as lon g-duration reconnaissance and exploration, due to their efficient propulsion. Th e manta wings' deformation is evident during the swimming process." Funders for this research include the National Key Research and Development Prog ram, National Key Research and Development Program, National Natural Science Fou ndation of China (NSFC), Ningbo Natural Science Foundation. The news reporters obtained a quote from the research from Northwestern Polytech nic University, "To improve the propulsion performance of the unmanned submersib le, the study of the deformation into the bionic pectoral fin is necessary. In t his research, we designed and fabricated a flexible bionic pectoral fin, which i s based on the Fin Ray ®effect with active and passive deformation (APD) capabi lity. The APD fin was actively controlled by two servo motors and could be passi vely deformed to variable degrees. The APD fin was moved at 0.5 Hz beat frequenc y, and the propulsive performance was experimentally verified of the bionic pect oral fins equipped with different extents of deformation. These results showed t hat the pectoral fin with active-passive deformed capabilities could achieve sim ilar natural biological deformation in the wingspan direction. The average thrus t (T) under the optimal wingspan deformation is 61.5% higher than the traditional passive deformed pectoral fins."
