Abstract
Within low Reynolds number (Re) environments, swimming robots need to perform non-reciprocal motions to propel themselves. The fundamental method to achieve this type of motion is by generating progressive waves (also known as traveling waves) that travel along the robot flagellum from the head to the free end. This work focuses on a simple way to generate progressive waves under low Re conditions that consists of the periodic oscillation of a passive flexible flagellum. For propulsion testing, a prototype of single-acting swimming robot based on the scotch-yoke-lever mechanism is presented, which allows to convert the rotational motion of a motor into an angular oscillation traveling along the flagellum. Also, an image-based algorithm is developed in MATLAB to identify the motion performed by the robot, i.e., to determine the characteristics of the swimmer in propulsion. Experimental results show that the robot is able to perform a non-reciprocal motion under low Re conditions.
