Abstract
A new study on robotics is now available. According to news reporting originating from Nanjing, People’s Republic of China, by NewsRx correspondents, research stated, “Three different hovering modes, namely, the caudal fin, pectoral fins, and multi fins, were utilized to achieve the standingand- hovering behavior in robotic dolphins.” Financial supporters for this research include National Natural Science Foundation of China; State Key Laboratory of Robotics And System. The news reporters obtained a quote from the research from Southeast University: “A three-dimensional dolphin model, consisting of body, caudal fin, and symmetric pectoral fins, was used as the virtual swimmer to implement three hovering modes. A novel paddling motion was proposed, and a symmetric shape was designed of the pectoral fins. The hovering mechanisms of different modes were revealed, and the mapping relationships between different motion and performance parameters such as hovering height, efficiency, stability, and rapidity were established. The respective advantages of the three hovering modes were compared. The results showed that the caudal fin mode had the best hovering stability, while the pectoral fins mode had the best hovering rapidity. Moreover, it is worth noting that the multi fins mode had both the good hovering stability and rapidity.”
