Swimming force characterizations of multistaged bi-helical microswimmer and 3D vortex trap manipulation [PDF]

Microelectronic Engineering, 2021
Abstract Vortex trap manipulation of microscopic objects in three-dimensions by helical microswimmers has a great potential towards non-contact biological cell manipulation or microassembly. However, in the current state-of-the-art, it has been limited in 2D manipulation due to the conflicting characteristics of optimizing the trapping force and ...

Image-Based Visual Servoing of Helical Microswimmers for Planar Path Following

IEEE Transactions on Automation Science and Engineering, 2020
Magnetically actuated microswimmers have attracted researchers to investigate their swimming characteristics and controlled actuation. Although plenty of studies on actuating helical microswimmers have been carried out, robust closed-loop controls should be still explored for practical applications.

3-D Autonomous Manipulation System of Helical Microswimmers With Online Compensation Update

IEEE Transactions on Automation Science and Engineering, 2021
Steering microswimmers toward 3-D autonomous manipulation tasks has received extensive attention. Our previous works have accomplished autonomously manipulating microswimmers in the 2-D space. This article aims to extend the 2-D autonomous manipulation to 3-D autonomous manipulation.

Magnetic Actuated Shape-memory Helical Microswimmers with Programmable Recovery Behaviors

Journal of Bionic Engineering, 2021
Inspired by bacterial flagella in nature, magnetic helical microswimmer is an ideal model to perform complex task in a low Reynolds number environments. Shape Memory Polymers (SMPs) with desirable properties are considered as one of the most preferred options for the development of small-scale robots. However, fabricating and programming strategies are

Magnetic Helical Microswimmers Made by Spirulina through Electroless Nickel Plating

2018 IEEE 13th Annual International Conference on Nano/Micro Engineered and Molecular Systems (NEMS), 2018
We present a simple technique to fabricate magnetic helical microswimmers with excellent surface quality and swimming performance. These were obtained through depositing a nickel film on the Spirulina biotemplates by electroless nickel plating. The morphology and coating composition of the as-prepared microswimmers were analyzed.

Closed-loop 3D path following of scaled-up helical microswimmers

2016 IEEE International Conference on Robotics and Automation (ICRA), 2016
This paper addresses the problem of 3D path following of magnetic helical microswimmers in closed-loop. An error kinematic model in a local frame with sideslip and attack angles is used to express the motion of the helical microswimmer. A new derivation of the chained form with three inputs and five states is used to linearize the kinematic model in ...
