This article presents verifying the initial and final states and motion capabilities of the cube fidget toy model from the perspective of the parallel robot structure model. A cube-shaped fidget toy that can change its state from space to semi-expanded. This is a combination of entertainment toys and the Japanese art of Origami. Whether this cube can achieve the desired design state is beyond our imagination because the spatial motion of one face dictates the motion of the other face and there exist follow-on motions of certain faces. Therefore, mathematical verification is necessary to ensure that the box can move and achieve the required state before it is manufactured. The method of modelling the structure in the form of a parallel robot has been applied in this article and gives the exact results as the desired design structure. This modelling technique can also be applied to resolve other complex structural problems.
