This model features four wood sticks attached to a series of 4 V-shaped arms via multiple strings. The movements of the arms will be locked as a pair due to the gear structure at the bottom of the arm. The arms have the tendency to fall down, creating tension in the strings. The strings that connect the wood sticks to the arms then act as the tensile force that pulls the sticks towards the arm. At the same time, the strings connected to either end of two sticks would pull the sticks together while regulating the direction of the force.
