Abstract
Eukaryotic flagella possess two singlet microtubules and nine outer doublet microtubules. Protuberances of protein named as dyneins, are placed along doublet microtubules. Dyneins produce the sliding force of doublet micrutubules. Bending of flagella is generated by the active sliding doublet microtubules. We have made artificial propulsion mechanisms in water modeled on the active sliding between two doublet microtubules. Electromagnetic actuators corresponding to the function of dyneins were placed along two flexible beams. To ensure larger active sliding, we modified the arrangement of electromagnets for the electromagnetic actuators.. The thrust force of the propulsion mechanism in water was discussed.
