, are the exterior angles made by the center link and the two arms. The approximate rectangle (green) represents the distance optimizer of the moderate strokes of Tam and Hosoi. The (blue) dumbbell is a large stroke that outperforms the moderate stroke. The approximate (light-blue) circle in the center represents the efficiency optimizer of the moderate strokes found by Tam and Hosoi. The off-center (red) wobble oval is a large stroke with higher efficiency.Reuse & Permissions
