21HM_X01

Our model features four wood sticks attached to a series of 4 V shape arms via multiple strings similar to our first project. 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, thus creating compression force on the strings. The strings that connect the wood sticks to the arms then acts as the tensile force that pulls the sticks towards the arm.
