CoG x , y ( t ) trajectory obtained with two different approaches. The shadowed gray represents the normal distribution pattern for the CoGx,y(t) trajectory, whose mean μ is represented by the dark green line. The red starred line stands for the CoGx,y(t) trajectory obtained with our physical model while the blue crossed line represents a trajectory computed from a classical pendulum model.
