Fig. 6. Mean angular positions of the (A,C) head (triangles) and (B,D) trunk (circles) segments in the pitch plane during walks and gallops by (A,B) hanumans and (C,D) bonnets (N=10 cycles/gait/species). Within each graph, the clusters of symbols to the left (lower velocities) are for walks, whereas the clusters to the right (higher velocities) are for gallops. Note that in both species, the range of mean positions for each segment is very similar during both walks and gallops.
