Fig. 5. Percentage differences against leg angle for (A) horizontal position
x, (B) vertical position y, (C) horizontal velocity
Vx, (D) vertical velocity Vy, (E)
horizontal acceleration Ax, (F) vertical acceleration
Ay, (G) resultant leg force F and (H) total
mechanical energy ME. Note the y-axis scale varies for each
subplot. The grey bars represent solutions within the leg angles used by
animals.
