Article Correctness Is Author's Responsibility: Discovery of ray sperms’ unique swimming motion and demonstration with bio-inspired robot

(City University of Hong Kong) It is generally agreed that sperms 'swim' by beating or rotating their soft tails. However, a research team led by scientists from City University of Hong Kong (CityU) has discovered that ray sperms move by rotating both the tail and the head. The team further investigated the motion pattern and demonstrated it with a robot. Their study has expanded the knowledge on the microorganisms' motion and provided inspiration for robot engineering design.
