Figure 2


Fig. 2. Scatter plot showing the variation in velocity and acceleration of all collected bipedal strides (N=43). Only the trials with little or no acceleration (A=0±0.2 m s-2; white band on plot) are included in the statistical analysis. The triangles (at 1 m s-1, 1.5 m s-1 and 2.0 m s-1) indicate the example strides that are illustrated in Fig. 3.
