本文报道了一种游动机器鳗在稳定游动和推力大于阻力的情况下的水动力学实验。机器人的运动是基于活的七鳃鳗的游泳，这由一个类似于Tytell和Lauder为美国鳗鱼开发的方程来描述(J Exp Biol 207：1825-1841,2004)。对于稳定的游泳，尾流结构非常类似于美国鳗鱼，在每个尾部跳动周期中，会有两对相同的符号涡流脱落，使尾流具有2P结构。推力估计表明，推力的主要部分是在尾部或接近尾部产生的。
Experiments are reported on the hydrodynamics of a swimming robotic lamprey under conditions of steady swimming and where the thrust exceeds the drag. The motion of the robot was based on the swimming of live lampreys, which is described by an equation similar to that developed for the American eel by Tytell and Lauder (J Exp Biol 207: 1825-1841, 2004). For steady swimming, the wake structure closely resembles that of the American eel, where two pairs of same sign vortices are shed each tail beat cycle, giving the wake a 2P structure. Force estimates suggest that the major part of the thrust is produced at or close to the end of the tail.
