Visual signaling from biologically - inspired robots has been used to investigate the behavior of birds [27]--[31],
dogs [32], lizards [33], fish [22], [34]--[42], and rats [43]; salient chemical cues have been implemented on a miniature mobile robot to investigate social behavior of cockroaches [44]; audio feedback has been integrated in a model of a
robotic squirrel to influence squirrels» behavior [45]; pulsing air currents
created by
robotic honeybees have been used to investigate honeybees» dance [46]; and hydrodynamic cues from a swimming
robotic fish have been considered in [20] to modulate fish behavior in a water tunnel.
