Abstract
We propose a two dimensional model swimmer consists of spheres linked by elastic springs which can be stretched and bent. This swimmer performs nonreciprocal periodic motions that breaks time reversality and it can swim in low Reynold’s number. We show that the velocity increases as the stretch constant increases. In the second part we place two of these swimmers in a viscous fluid and calculate the effect of hydrodynamic interactions on the average velocity.
