Anonymous leadership and stochastic resonance in collectives of self-propelled robots

"We investigate the influence of an anonymous leader on a collective of self-propelled robots using Kilobot experiments and numerical simulations. {Each robot possesses a binary internal state that determines the direction of its intrinsic rotational motion, leading to clockwise or counterclock...
