| Swimming microrobots are miniature machines which can be designed and fabricated using microelectromechanical systems (MEMS) technology. They can play a key role in many biomedical applications, such as controlled drug delivery, microsurgery, and diseases monitoring. Many researches have been carried out on micro swimming methodologies. Also, different propulsion mechanisms have been introduced for 1-DOF microswimmers. The objective of this work is to study a flagellar microswimmer with controlled maneuvers. The propulsion mechanism used in our design contains two prokaryotic flagella, rotating into the fluid media, leading to microrobot movement. In this study, we have tried to focus on dynamic modeling of the motion proposed for the swimming microrobot. Then, an appropriate control law was developed in order to control the microrobot maneuvers. The resistive-force theory was used in order to determine the hydrodynamic force created by the rotary motion of each flagellum into the fluid media. Feedback linearization method was used to control the motion of microrobot for tracking performance. The results obtained revealed that microrobot can be controlled in such a way that the desired maneuver can be performed by applying the designed controller. | ||
