Using a one-dimensional damped and parametrically driven diatomic nonlinear coupled pendulum lattice ,we find for the first time in the macro-experiment that the amplitude of localized soliton is stable, quasiperiodic, periodic or random depending on the driven parameter. Theoretically, these experimental results can be explained by the solution of a quintic nonlinear Schr?dinger equation.
