A New Theory of Micro-Robots: multiple scales & distinguished limits

Friday 28th June 2013 - 16:25 to 16:50
INI Seminar Room 1
This paper is devoted to the theory of three types of micro-robots consisting of rigid spheres connected by rods or springs of oscillating lengths:

1. N-sphere linear micro-robot;

2. Dumbbell micro-robot driven by flow oscillations;

3. Triangular micro-robot;

In all three cases the velocities of self-propulsion and the angular velocity of self-rotations have been calculated analytically with the use of the two-timing asymptotic procedure. The results are discussed and compared with the known experiments and with the results of other authors.
