# Self-propulsion of V-shape micro-robot

@article{Vladimirov2012SelfpropulsionOV, title={Self-propulsion of V-shape micro-robot}, author={Vladimir A. Vladimirov}, journal={arXiv: Fluid Dynamics}, year={2012} }

In this paper we study the self-propulsion of a symmetric V-shape micro-robot (or V-robot) which consists of three spheres connected by two arms with an angle between them; the arms' lengths and the angle are changing periodically. Using an asymptotic procedure containing two-timing method and a distinguished limit, we obtain analytic expressions for the self-propulsion velocity and Lighthill's efficiency. The calculations show that a version of V-robot, aligned perpendicularly to the direction…

It is shown how to cast the problem of swimming in the language of control theory, prove global controllability (which implies that the three-sphere swimmer can indeed swim), and propose a numerical algorithm to compute optimal strokes (which turn out to be suitably defined sub-Riemannian geodesics).
