The team's first functional prototype is shown in the images below.
Movement
In the two videos, the full revolution of the mechanism is shown. When the crank is rotated, there is a distinct "flicking" motion as estimated by our kinematic analysis. The flicking motion occurs at the bottom of the revolution of the joint 6.
