Another mechanism that the developed device utilizes is the cam cleat. This is the same concept sail boats already use to hold the ropes on the boat itself. If a rope is pulled in tension one direction as seen in Figure 2, the internal torsional springs of the cam cleat create a rotation compression force to grip the rope. As more tension is applied to the rope, the torsional springs are able to apply more gripping force to the rope itself. This enables powerful rope holding ability without the need for external, powered force generation.
