Abstract
A robotic fish includes a front body, a rear body that includes a first segment and a second segment, and a driving unit. The first segment has a front engaging portion projecting toward and pivotally connected to the front body, and a rear engaging portion formed with a recess that recedes toward the front body and pivotally connected to the second segment. The driving unit includes a motor disposed in the front engaging portion, and a shaft extending along a dorsoventral axis and connecting the motor and the rear connecting portion. A ratio of a distance between the shaft and a foremost edge of the front engaging portion to a distance between the foremost edge and an extreme point of the recess ranges from 0.075 to 0.75.
