  We present in this fluid dynamics video a novel experimental setup with
self-propelled swimmers on a free surface. The swimmers, modeled as flexible
thin filaments, are subjected to external electromagnetic forcing driving a
propagating elastic wave that gives rise to self- propulsion. The
fluid-structure interaction problem of these passive anguilliform swimmers is
analyzed in:
